Hello and welcome to I Know Dino. Keep
0:38
up with the latest dinosaur discoveries and science
0:40
with us. I'm Garrett. And
0:42
I'm Sabrina. And today in our
0:44
519th episode… We're
0:47
celebrating a hundred years of
0:49
velociraptor! Ah, nice. Also, it's Dino-vember.
0:52
And with velociraptor, you kind of have
0:55
to talk about Henry Fairfield Osborn, who
0:57
named velociraptor. So, we'll talk
0:59
about him a little bit. There's a lot going
1:01
on. There is. Velociraptor
1:03
is definitely a top ten, maybe
1:05
top five most popular dinosaur. Yes,
1:08
and very famous thanks to Jurassic Park.
1:11
We could have done the hundred year anniversary
1:13
of… I forget what the other dinosaur
1:15
was named in the same paper. Sittacosaurus,
1:18
I want to say? Sauronathoides?
1:21
It's Sauronathoides. There we
1:23
go. Second tries the charm. Sauronathoides
1:25
is named in that paper. But
1:28
there's also oviraptor. Oh,
1:30
yeah. Oviraptor is another pretty
1:32
popular one. It's a big day. This
1:35
paper came out November 7th of 1924. It's
1:38
pretty good. We don't always know the exact date.
1:40
Sometimes it's just the month. We
1:43
also have a fun fact,
1:45
which is that paleobiologist Zofia
1:48
Kielin Yavarosky not only found
1:50
the fighting dinosaurs, which includes
1:52
Velociraptor and Protoceratops, she
1:55
also discovered Dinocyrus and Galomimus.
1:58
Yeah, she's got a lot of greatest hits there. Yes,
2:00
and if you want to learn more about her, don't
2:02
worry. We'll have an upcoming episode all about her soon.
2:06
Which reminds me, I know that because
2:08
we're on parental leave. We're
2:11
expecting our second baby any day now, so
2:13
it seemed like a good idea to record
2:15
some episodes ahead of time. And
2:17
with a toddler and now a baby on
2:19
the way, it was a little bit too
2:22
difficult for us to prep weekly episodes ahead
2:24
of time, like we did last parental
2:26
leave. So we're going to
2:29
be experimenting with a biweekly format while
2:31
we're away. I hope you
2:33
enjoy our first parental leave episode. Yes.
2:36
Yeah, we did a survey last year, or at
2:39
some point, asking what people thought about
2:41
if we switched to biweekly. And
2:44
a lot of people, most people, said they would
2:46
be OK with it. So we're
2:48
going to see just how true that is. But
2:51
also, like Sabrina was saying, it
2:54
just wasn't practical for us to
2:56
prerecord months worth of weekly episodes.
2:59
Biweekly is still hard to prerecord because
3:01
we're basically recording two or three episodes
3:03
a week right now. Yes. Because we
3:05
are doing the I Know Paleo episodes,
3:08
getting ahead on the episodes as well as the
3:10
currently, in our time, weekly
3:15
episodes that are coming out. But if
3:17
you want dinosaur content
3:19
every week, make sure you sign up
3:21
for our newsletter because we were able
3:23
to write some stuff to fill in
3:25
the weeks in between. And
3:28
you can do that at inodino.com.
3:30
If you go to inodino.com/bonus, you'll
3:32
also get access to our bonus
3:35
I Know Paleo episode all
3:37
about terror birds. Yeah. And if
3:39
you want more I Know Paleo episodes and you're not
3:41
already a patron, you can sign up there and you'll
3:43
have plenty of episodes to fill in
3:45
those missing weeks. As
3:48
well as extended interviews, which I sometimes go back
3:50
and listen to because I forget what all people
3:52
told me. And it's kind of
3:54
fun to go back years and see what the
3:56
state of the science was when we were talking
3:58
to an expert on something. and also
4:01
just fun to revisit
4:03
those conversations. Yeah. So
4:06
that's all at patreon.com/ino dino.
4:09
And speaking of Patreon, we have some
4:11
patrons to thank this week. And
4:13
they are Toon Rex, Dr.
4:15
Eric Nefarious, Big Sheep, Daniel
4:18
McGill, Joao, Sti
4:20
Jackasaurus, Ryan the Biochemist,
4:23
Sorapod Susan, Sonia,
4:25
and Katie. Thank you
4:27
so much for being a dino at all in
4:29
our community. Seriously, your support is why
4:31
we're able to keep the show going, especially when
4:33
we need to take time off because we're having
4:35
a baby. Yes. Yes,
4:38
thank you all very much. All
4:40
right, jumping in, it's the beginning
4:42
of November, which means
4:44
it's dino-vember. I think we
4:47
usually talk about dino-vember, but kind of dove in
4:49
for this year. Basically an
4:51
art month, right? Drawing dinosaurs is the
4:53
idea. It's kind of like Elf on
4:55
a Shelf, but with dinosaurs? Oh,
4:58
that's right, I forgot. Yeah, it
5:00
started in 2012 with Susan
5:02
and Rafe Tuma. They made
5:05
their toy dinosaurs come to life and be up
5:07
to no good. So there's your Elf
5:09
on a Shelf thing. And they did
5:11
it for their kids so that they'd have
5:13
a sense of wonder and imagination, and so
5:16
they could all have fun together. Their website
5:18
says it's a month-long imagination invasion. It
5:20
kind of started because their youngest kid didn't
5:23
sleep through the night, so Susan started setting
5:25
up scenes with the dino toys to pass
5:27
the time, and they wanted something fun
5:29
for their older kids because they were too
5:31
tired to take the older kids out every day. In
5:33
the first year that they did it, the kids woke up
5:35
to find dinosaurs that got into some cereal and made a
5:37
mess in the kitchen, and they really liked it, so kind
5:40
of snowballed from there. Now they even have a book about
5:42
it that came out a few years ago. There's
5:44
one scene that involved 600 pounds
5:47
of ice cubes strewn across the
5:49
kitchen floor. So it got pretty
5:52
intense, it sounds like. Yeah,
5:54
that sounds like a mess. Those are brave
5:56
parents making that big of a mess for
5:58
themselves to clean up. Yeah, maybe their
6:01
kids helped maybe yeah, you
6:03
gotta clean up the mess after the dinos So
6:07
now a lot of people celebrate dinovember, I
6:10
know libraries schools and museums often make
6:12
announcements about it Am
6:14
I just completely mixing it up with something else
6:16
where a lot of people draw a dinosaur a
6:18
day? Yes for dinovember That's a
6:21
different month. I believe April. Okay Which
6:24
the name is escaping me Apparently
6:27
there's national draw dinosaur day, which
6:29
is January 30th Hmm,
6:31
it's just any excuse to draw dinosaurs.
6:33
You could draw dinosaurs all year.
6:35
It's only fine. Yeah So
6:38
if anyone celebrates dinovember, let us
6:40
know we would love to hear
6:42
some details You can send
6:45
that along via our feedback format
6:47
bit.ly slash dino questions Bonus
6:49
points if you also use 600 pounds of ice cubes
6:53
Was it 600 pounds I
6:55
was thinking it was 600 individual ice cubes
6:57
600 pounds of ice cubes Yes,
7:00
I read something about they used up 600
7:02
pounds of ice cubes Maybe it took them
7:04
a few tries to get what they were going
7:06
for so much ice There's
7:09
a lot of ice. So now that
7:11
we've covered dinovember. Let's talk about Henry
7:15
Fairfield Osborn Because
7:17
again on November 7th of 1924
7:19
so almost exactly a hundred years
7:21
ago from when this episodes airing
7:24
He named velociraptor and sworn
7:27
authorities and over raptor. But again, we're
7:29
focusing on velociraptor So
7:31
Henry Fairfield Osborn senior was
7:34
known for a lot of things He
7:36
was the president of the American Museum of
7:38
Natural History in New York for 25 years
7:40
and he named a number of dinosaurs He
7:43
became president of the American Museum of Natural History's Board of
7:45
Trustees in 1908 and served until 1933 He
7:49
also served as president of the New York Zoological Society
7:51
from 1909 to 1925 He
7:55
had a lot of paleontology awards and
7:57
he described and named multiple dinosaurs including
8:00
Ornitholestes in 1903, Tyrannosaurus rex in 1905, Albertosaurus
8:05
in 1905, Pentiseratops in 1923, and
8:10
then of course Velociraptor in 1924. And
8:13
Overraptor and Sornithoides. We can say that
8:15
every time? Maybe. I
8:18
don't know. I just
8:20
think it's so cool that especially Overraptor and Velociraptor
8:22
are both very common dinosaurs and the fact that
8:25
they were both named in the same paper, which
8:27
is only a few pages long is
8:29
pretty interesting. Yeah, they're just a few paragraphs apart.
8:32
As a curator, he worked with a
8:34
lot of fossil hunters and preparators, including
8:36
William King Gregory, Roy Chapman Andrews, Barnum
8:39
Brown, and Charles Knight. I
8:41
think we've talked about most of those people on our show.
8:43
Oh, definitely, yeah. He was
8:45
also senior vertebrate paleontologist of the US
8:47
Geological Survey in 1924. His
8:50
focus was on exhibits at the
8:53
American Museum of Natural History, murals,
8:55
dioramas, dinosaur mounts, and
8:58
he got a lot of visitors to the museum,
9:00
but not all scientists and researchers appreciated it at
9:02
the time. Yeah, some
9:04
people thought that the scientific study
9:07
wasn't meant for the public, and
9:09
it should be reserved for people that are
9:11
studying the science. They didn't want it to
9:13
be a big spectacle, which I
9:16
thought was really funny because Barnum Brown was
9:18
part of it, and he's literally named after
9:20
a guy who created the
9:22
circus. Yes. But
9:25
that's not why he got into it. Yeah.
9:28
Now, Osborne did have
9:30
racist and eugenic beliefs, which
9:33
did appear in the museum's exhibits and
9:36
educational programs. It's worth noting many of
9:38
his peers or contemporaries disagreed with his
9:40
beliefs, so that's nice. It is, yeah.
9:43
Usually people sort of do a wide
9:45
paintbrush and say, you know, everybody was
9:47
doing it at the time, but I
9:49
guess it wasn't everyone at the time.
9:52
It was common because they
9:54
even did a convention
9:56
on basically eugenics at AMNH while
9:58
he was doing it. was the
10:00
director there. He
10:03
was also the co-founder of the American Eugenics Society
10:05
in 1922, and he said that heredity
10:09
was superior to influences from the
10:11
environment. He
10:14
believed in progressive evolution and didn't think
10:16
that mutations and natural selection played a
10:18
role in evolution. He was a little
10:20
behind the time, and those a lot
10:23
behind the time in some ways, a little behind the
10:25
time in others. Yes. He
10:28
also had a theory on human origins called
10:30
the Dawn Man theory. It's based
10:32
on the discovery of the Piltdown Man, a bone
10:35
fragment said to be a previously unknown
10:37
early human before it was exposed as
10:39
a hoax. It took 41
10:41
years to be exposed as a forgery that
10:43
it came from three different species. Yeah, that's
10:45
a really famous case of critical
10:48
thinking missing. Yeah. They
10:51
got there. He also
10:53
argued that humans had a common ancestor
10:55
with apes, and all apes evolved parallel
10:57
to ancestors of humans. He
10:59
denied that the common ancestor was ape-like
11:01
and said it was more like a
11:03
human. Yeah, it doesn't work well with
11:06
eugenics if you descended from an
11:08
ape and you're trying to talk about how
11:10
superior people are or certain
11:12
people are. Yes. So
11:15
there are definitely things to be
11:17
aware of when studying Henry Fairfield
11:19
Osborne. Yeah, and unfortunately, the exhibits
11:23
that he created while he was there had
11:25
a lasting impact. Mm-hmm. For
11:27
example, part of the reason that a lot of
11:29
the early ape dioramas have
11:31
dark skin is because of his eugenics
11:33
beliefs. Yes. But
11:36
going back to his life in
11:38
general, he was born in 1857 in
11:40
Fairfield, Connecticut, four
11:43
years before the Civil War, which
11:45
sometimes I forget about putting it
11:47
in these historical perspectives. Yeah. Being
11:50
born during the time of slavery, I'm sure,
11:53
did not help with his
11:55
few different races. Yes.
11:58
He lived until 1935. and he
12:00
came from a wealthy family. He
12:02
was the eldest son of shipping
12:04
magnet and railroad tycoon William Henry Osborne
12:07
and Virginia Reed Sturgis. His
12:09
younger brother was William Church Osborne who
12:11
was president of the Metropolitan Museum of
12:14
Art. He had another brother
12:16
who drowned in the Hudson River when they were young.
12:19
That brother had a collection of local birds which were
12:21
later presented to the AMNH. Osborne
12:24
studied at Princeton University. He got a
12:26
BA in geology and archaeology. He
12:28
was mentored by Edward Drinker Cope, so you can imagine
12:31
which side of the Bone Wars he was on. He
12:35
also studied embryology and comparative anatomy
12:37
under Thomas Huxley and Francis Maylin
12:40
Balfour. It's interesting though because he
12:42
is from Connecticut. So you'd think maybe he was
12:44
a Marsh guy since that's where Marsh was from.
12:48
Well, he and Marsh had some clashes. He
12:51
married his wife Lucretia Thatcher Perry in 1881.
12:53
They had five children including
12:56
Henry Fairfield Osborne Jr. who was
12:59
a naturalist and conservationist. And
13:01
then of course Henry Osborne Sr.
13:03
was professor of zoology at Columbia
13:05
University in 1891 and
13:08
curator of the Department of Vertebrate Paleontology at
13:10
the AMNH the same year. He's
13:12
also the author of over 12,000 printed
13:15
pages in his lifetime. Is that
13:17
a lot? I don't know. That's
13:19
a lot, especially for his lifetime,
13:21
I think. Yeah, I guess
13:23
that if you what's a typical book like 400, 500?
13:29
200? Okay. Yeah, that's a lot of books. Osborne
13:34
died suddenly in 1935. His
13:37
wife had died in 1930 after a
13:39
nearly year long illness. So
13:41
that's just to give you some background of his life. There's
13:44
several animals named after him. Serolophus
13:47
Osbornei, for example, was named by Barnum
13:49
Brown in 1912. Then
13:52
there's the crocodile Osteolamus
13:55
Osbornei, named by Carl
13:57
Patterson Schmidt in 1919. In
14:00
1937, so a couple years after
14:02
he died, William Gregory presented a
14:04
biographical memoir of Osborne, and
14:07
it's full of praise. There's
14:09
also some interesting tidbits about his life and
14:11
how he became a paleontologist. For
14:13
example, as a child, he didn't really collect things.
14:16
His father encouraged him to do scientific work and even
14:18
built him a lodge for his work. While
14:21
a student at Princeton, Osborne and
14:23
two other students, including W.B. Scott
14:25
and Francis Spear Jr. decided they
14:27
didn't want Yale University to, quote,
14:29
have a monopoly in fossil hunting
14:31
expeditions in the West, end
14:33
quote. That sounds like it might be
14:35
referencing Marsh. A little bit. But
14:39
I think, yeah, I think it all kind of came together.
14:41
So when he was 20, they went on an expedition. This
14:43
is in 1877. They
14:45
collected fossil fish and plants in Colorado and
14:48
fossil mammals in Wyoming. They
14:50
studied the fossils and made drawings
14:52
and wrote descriptions and expressed gratitude
14:54
to Lady and Cope. Both
14:56
helped him a lot throughout his early career.
14:59
And then the next summer, they led a second
15:01
Princeton expedition to Wyoming and they found mammals. Osborne
15:04
wrote, quote, in any event, the discovery
15:07
of new principles is the chief end
15:09
of research. As Darwin observed, the true
15:11
naturalist is not content with merely assembling
15:14
facts. His chief desire is to seek
15:16
interpretations and explanations. In other words, to
15:18
discover new principles. I
15:20
have myself always found the mere assemblage
15:22
of facts an extremely painful and self
15:24
denying process. And I've always been
15:26
animated by the hope that such dry work would
15:29
finally be rewarded by an interpretation or the discovery
15:31
of a new principle, end quote. That
15:33
might explain why he was into the exhibits. Yeah.
15:35
And possibly why he was sort of
15:38
rejecting some of the main scientific
15:40
theories of the time, because he's always
15:42
trying to find, sounds a little bit
15:44
contrarian in a way where it's like,
15:47
I'm looking for something new. I'm bored
15:49
with just collecting data and the status
15:51
quo. Yeah. So like
15:53
he said, he was on Cope's side of the bone wars.
15:56
When he described a new
15:58
animal, lurocephalus. He said, quote,
16:01
this may eventually prove to be a
16:03
species of telematherium, marsh, but the description
16:05
given by him is so brief and
16:07
uncharacteristic that it might apply to any
16:09
of the allied genera, end quote. A
16:12
little bit of shade there. A little
16:14
bit. Marsh did such a bad job
16:16
describing this animal that I might as
16:18
well just rename it anyway. Yeah. Yes.
16:22
He also implied that marsh followed Lady
16:24
in exploring the Bridger beds in Wyoming,
16:26
which marsh denied. So
16:28
Osborn and Marsh clashed over Mesozoic mammals and
16:30
they ended up writing mean reviews of each
16:33
other's work. I don't know how Marsh found
16:35
the time when he was writing all these
16:37
mean reviews of Cope's work, but there
16:39
you go. Maybe he hired ghostwriters to
16:41
throw shade for him because he was
16:43
so busy. Maybe. Or
16:46
he just spent a lot of his time on Grudges. It
16:49
could be. It sounds like he did. I
16:51
think everybody involved intimately
16:54
in the Bone Wars spent a lot of time
16:56
on Grudges. Yes. Which speaking of,
16:58
well, I don't know if this is probably
17:00
not because of a grudge, but the American
17:03
Museum of Natural History did purchase Cope's collection
17:05
of fossils, partly because of Osborn. Oh
17:08
yeah. He was very much on Cope's side.
17:10
Yeah. And Cope needed money late in life,
17:12
so that would have helped. And
17:14
that really worked out for AMNH. Some of
17:16
those fossils are hugely important. Oh yeah. I
17:19
mean, a lot of things worked out for a
17:21
lot of people because of Cope and Marsh. Yeah.
17:25
Yeah, Osborn, usually when
17:27
I hear his name, I think
17:30
of the eugenics, unfortunately. Me too.
17:32
Just because he had
17:34
such a big impact on it and really
17:37
emphasizing it with such a high
17:39
position in paleontology,
17:42
which is a real bummer because, like you
17:45
said, velociraptor, sore anathotes,
17:47
and oviraptor. Plus
17:50
Tyrannosaurus rex. Yeah. So
17:53
in dinosaur science, he is a really big name. And
17:56
I'm sure he helped popularize
17:58
dinosaurs. But yeah,
18:00
it's just so tainted. It's unfortunate. Mm-hmm.
18:03
Yeah, that happens sometimes with these
18:05
big figures in paleontology. But
18:08
we do have them to thank for Velociraptor. So
18:10
at least there's that. Yes.
18:12
And speaking of, we will get to our
18:14
Dinosaur of the Day Velociraptor in just a
18:16
moment, but first we're going to take a
18:18
quick break for our sponsors. This
18:22
episode is brought to you by Princeton University
18:24
Press. Their fantastic new book,
18:27
Uncovering Dinosaur Behavior by Dave Hone,
18:29
was just released. It's
18:31
a comprehensive explanation of what we
18:33
know about dinosaur behavior and which
18:35
scientific studies got us here. We'll
18:38
be doing a book club episode
18:40
discussing uncovering dinosaur behavior on December
18:42
4th, so get your copy now.
18:45
We are really enjoying the book so far. Oh
18:48
yes, it's really approachable and easy to
18:50
read and understand, and makes it clear
18:52
too how far the science has come
18:55
since people first started studying dinosaurs. I
18:58
love the Spinosaurus and Baryonyx
19:00
analyses. They both have absolutely
19:03
gorgeous illustrations by Gabriel Ugueto.
19:06

19:13
And while you're there, check out their
19:15
other excellent recent dinosaur books. There's Birds
19:18
of the Mesozoic, which is formatted like
19:20
a field guide for birdwatching in the
19:22
Mesozoic, and it also includes the evolution
19:24
to modern birds. There's also
19:27
the Princeton Field Guide to Predatory Dinosaurs,
19:29
which includes 300 theropods with
19:31
length and weight estimates, as well
19:34
as detailed illustrations, skeletons, and some
19:36
illustrations that show off the muscles.
19:39
And the Little Book of Dinosaurs, which is a
19:41
pocket-sized book that really lives up to its name.
19:44
It's like having a mini-encyclopedia of dinosaurs
19:46
with some really cool illustrations. The
19:49
promo code PUP30 will work
19:51
on all those books, too. The
19:53
most important thing, though, is to make sure you get

20:47
speaking of Velociraptor, we'll
20:49
now get onto our Dinosaur of the Day. I'm
20:52
going to say it's Velociraptor Revisited because it was
20:54
our Dinosaur of the Day in episode
20:56
83. It's
20:59
weird to hear a two-digit episode. It
21:02
is. We also discuss Velociraptor
21:04
quite a bit as part of our
21:06
Raptor Renaissance episode, episode 500. But
21:10
it's such a famous and cool dinosaur. It's kind
21:12
of like how could we not talk about it
21:14
on the 100-year anniversary? Sorry,
21:17
Sorenathoidis and overraptor. Yeah.
21:23
Velociraptor was a Dromaeosaurid theropod that
21:26
lived in the Late Cretaceous in
21:28
what is now Mongolia and China,
21:30
found in the Jadokda Formation and Bayan-Mandahu
21:33
Formation. Again, it was named
21:36
November 7, 1924 by Henry Fairfield Osborn. 100-year
21:40
anniversary. Dromaeosaurs were
21:42
closely related to birds, their sister
21:44
group. They're small to
21:46
medium in size and feathered. They
21:48
lived in the Cretaceous, though some isolated teeth had
21:51
been found from the Middle Jurassic and
21:53
they lived all over the world. They
21:55
were very bird-like and smart. They
21:57
had long arms with sharp claws, which were good
21:59
for birds. grasping their best known
22:01
though for those sickle like claws on their
22:03
second toes, which they would
22:06
hold their second toes off the ground while walking and
22:09
only their third and fourth toe bones
22:11
would bear their weight. So they were
22:13
functionally didactyl. Yes, because the first toe
22:15
also is way up off
22:17
the ground. Mm hmm. Barely even.
22:19
Small, very small. Kind of like
22:22
a duclon, a dog or something. So
22:24
if you see a track of a velociraptor, it's literally
22:26
just two toes and a little tiny
22:28
bump at the base for where that
22:30
like kind of first foot bone
22:32
is. Yeah. And
22:35
they might have used those second toe claws for
22:37
going after prey and climbing trees. So it was
22:39
important to keep them sharp. Yeah. And
22:41
not necessarily the same throughout their whole life too. When they were
22:44
younger, maybe it was more important to be able to climb a
22:46
tree or something. And when they're older, might've been more for attacking
22:49
things. Mm hmm. Of
22:51
course, velociraptor is iconic in Jurassic
22:53
Park and Jurassic World, but we'll
22:55
start with Jurassic Park because that's
22:57
what made it iconic. Yeah. Because
23:00
you've got Timmy and Lex, then you've got Blue.
23:03
It's a toss up, I guess. Because, yeah, Jurassic
23:05
World, it's definitely more of a character. It
23:07
depends on your age. I think
23:09
for people that were alive and
23:12
watching movies when Jurassic Park came
23:14
out, it's definitely a Jurassic Park
23:16
dinosaur. But for the
23:18
younger generations. It's all about
23:20
Blue. I think so. It's more of a Jurassic World
23:23
phenomenon. Yeah. Plus
23:25
Jurassic Park focused, I think, a little bit more on
23:27
T-Rex and a little bit less on the raptors. I
23:30
think you're right. But then they kept popping up.
23:32
They did. Subsequent films.
23:34
Yeah. Well, we talk about this a
23:36
lot on the show. Velociraptor in Jurassic Park was modeled
23:38
after Deinonychus, but then they also
23:41
made it the size of Utahraptor. And
23:43
Utahraptor was discovered right around the time the
23:45
movie was coming out. So it worked out.
23:48
It was quite a coincidence. Yes. There's
23:51
two paleontologists, Jim Kirkland, about this in episode 34.
23:54
And the way he puts it, Utahraptor is the star of
23:57
the movie. So he's on team raptor is where
23:59
the importance of the movie is. part of Jurassic Park,
24:01
not T-Rex. Well, he found Utah
24:03
Raptor, so that makes sense. I
24:06
remember he pointed out too that the
24:08
claw of Utah Raptor is way bigger
24:10
than the Velociraptor claw is in the
24:12
movie. It's one of the few cases
24:14
of things in Jurassic Park that look
24:16
kind of puny and not scary compared
24:18
to the real life animal. Yeah. So
24:22
Velociraptor looked bird-like, but it had a
24:24
very long tail and very big claws
24:26
and teeth. Well, regular size teeth, big
24:29
claws and sharp teeth. Yeah.
24:31
Big teeth for a bird. Yeah.
24:34
Birds don't have teeth. Yeah. Velociraptor
24:37
has been compared to eagles. You could
24:39
think of it like a land eagle.
24:42
It walked on two legs. It
24:44
had a long, low skull. It
24:46
was estimated to be up to almost seven feet
24:48
or over two meters long and weight up to
24:51
a 43 pounds or almost
24:53
20 kilograms. It had an upturned
24:55
snout and a triangular
24:57
jawbone. Its skull grew up
25:00
to over nine inches or about 23 centimeters
25:02
long. Its snout
25:04
was about 60% the length of the skull
25:06
and it was narrow. I feel like
25:08
I should mention too, even though it's
25:10
seven feet or about two meters long,
25:13
that means it's about a third of
25:15
that in height. So right
25:18
around two feet tall, maybe
25:20
two thirds of a meter tall. So
25:22
that's why I think dog sized is
25:24
a good way to describe it. Sometimes
25:27
they say turkey sized if
25:29
you're talking about it by weight because 43 pounds
25:31
is sort of the upper estimate of what it might
25:33
weigh. The long tail really
25:35
makes a difference for length. Yeah.
25:38
There's no good modern animal to compare these
25:40
animals to because they're so lightweight for their
25:42
size and they're also really long and skinny.
25:44
So they're sort of weird. They're almost like
25:47
a snake with legs or something in terms
25:49
of proportions, super weird, but sort
25:52
of dog or turkey. Like you're
25:55
saying the lightweight too, it's because it had
25:57
hollow bones. It also had a
25:59
wishbone. It had large hands with
26:01
three fingers on each hand and
26:03
claws on the hands. The tail
26:05
was stiff. The one specimen was
26:08
found with tail bones that curved sideways, so there's
26:10
some flexibility to move side to side. Not
26:12
too much though, because the vertebrae
26:15
on the tail really interlocked with
26:17
these extremely long processes sticking off
26:19
them that would link a dozen
26:21
vertebrae together. Right. And
26:24
again, it had the sickle-shaped claw on each of its
26:26
second toes. The sickle claws could
26:28
grow to over six and a half centimeters or
26:30
2.6 inches long. And
26:32
that's just the fossilized part. That's
26:35
just the bone, not the keratin sheath over
26:37
the top. Yeah. Yeah. So
26:40
you are really talking about like eagle talons
26:42
on this turkey. Eagle
26:44
talons on it too. Like
26:47
we said, it had four toes, but it only walked
26:49
on its third and fourth toes because that first toe
26:52
had a small dew claw and was a
26:54
small toe. And then the second one, it
26:56
held off the ground because it had that
26:58
large sickle-shaped claw. Want to keep
27:00
it sharp? Mm-hmm. Can't be dragging it on
27:02
the ground. Yes. It had a large
27:05
brain in proportion to its body size, so it's
27:07
probably intelligent. It was agile,
27:09
probably a fast runner. And
27:11
based on the scleral rings in the eyes, it
27:14
might have been nocturnal. Yeah,
27:16
maybe. Maybe. There
27:18
was a study from 2024 earlier this year by Yuan
27:21
Tingtze and others that found velociraptor
27:23
may be in between modern
27:25
diurnal and nocturnal animals. So somewhere
27:27
in between night and day. Yeah.
27:30
And it's also possible that all dinosaurs had the
27:32
scleral rings, which would mean the ones
27:36
that were nocturnal and diurnal. Yeah, they both
27:38
had them. There was
27:40
a study from 2023 by Sichiro
27:42
Tada and others that reconstructed the
27:44
nasal cavity of velociraptor mongoliensis and
27:47
compared it to modern endotherms and
27:49
ectotherms. And they found
27:51
that velociraptor probably couldn't cool its brain like
27:53
modern birds. It's possible
27:56
non-aving dinosaurs without a large nasal cavity didn't
27:58
need them because weren't as developed as birds
28:00
and didn't need to be as cooled down.
28:03
But the nasal cavity of Velociraptor was
28:05
not large enough to regulate heat for
28:07
a bird-like large brain. It
28:10
didn't need energy to hunt. It was warm-blooded
28:12
to some extent, but based on raptor growth
28:14
rates, it may have had a more moderate
28:17
metabolism. Quill knobs
28:19
have been found on Velociraptor arms,
28:22
their attachment points for feathers, which means
28:24
that Velociraptor had feathers. Its
28:26
arms, though, were too short to fly or glide,
28:29
so it may have used feathers to attract mates,
28:31
or help for brooding, or help it run faster
28:33
up slopes. Six quill knobs
28:35
have been found on a specimen, this was
28:37
in 2007, from the Jadokde Formation,
28:40
but it may have had 14 quill knobs on its arms. However,
28:43
that specimen with the quill knobs
28:45
may need to be reevaluated and
28:47
confirmed that it is actually Velociraptor.
28:50
Yeah, quill knobs are so cool
28:52
because they show that it had
28:54
large primary feathers attaching directly to
28:56
the bone, which still every time
28:58
I think about it, it sort
29:00
of makes me cringe a little
29:03
bit that they had feathers that went through
29:05
their skin and connected to the bone. But
29:09
it shows you how strong those feathers were
29:11
and that potentially they were using them for
29:13
flight. Yes, or brooding. Yeah,
29:15
or something more than
29:17
just insulation. So the reason
29:19
they need to confirm and reevaluate is
29:21
because there was another Dromaeosaur that was
29:23
found in that locality, Soggin, so
29:26
they just need to make sure that this one
29:28
with the quill knobs is Velociraptor. But
29:31
based on other Dromaeosaurs with feathers
29:34
like Genuanlong, Velociraptor probably did have
29:36
feathers. There's two
29:38
valid species of Velociraptor. There's Mongoliancis,
29:40
which is the type species, and
29:42
Osmulske, which was named in 2008.
29:46
There was a skull found in Inner Mongolia. The
29:49
genus named Velociraptor means swift Caesar,
29:51
and the species named
29:53
Mongoliancis refers to Mongolia where the fossils were
29:55
found. I've also heard it
29:57
called like rapid thief set of
29:59
spiders. Swift Caesar. Oh, yes. Yeah,
30:03
raptors often, it means thief or something
30:05
like that, so it just depends. The
30:08
species name Mongoliancis refers to Mongolia,
30:10
where the fossils were found, and
30:12
the species name Osmulske is in
30:14
honor of Polish paleontologist Halska Osmulske.
30:17
The first fossil of Velociraptor was found
30:19
in 1923 as part of an American
30:21
Museum of Natural History expedition to the
30:24
Gobi Desert in Mongolia. They
30:26
were found at the Flaming Cliff Site,
30:28
which is where Roy Chapman anders went
30:30
and we talked all about his expeditions
30:32
in episode 402, the indirect
30:35
inspiration to Indiana Jones. Yep, and
30:37
then Osborne, I guess, followed him
30:39
there a few years later.
30:42
Osborne did not follow him. Roy Chapman anders
30:44
was exploring for Osborne and would ship the
30:46
fossils back. Oh, I see. Okay.
30:48
And that's how Osborne ended up naming all
30:50
these dinosaurs, including Sauronathoidi is an oviraptor, because
30:52
we have to keep bringing that up. So
30:56
he named it, but he did not discover it.
30:59
Yes. All three of those dinosaurs he named in 1924
31:01
had skulls. Yeah.
31:04
They have really nice drawings to accompany the paper. As
31:07
Osborne put it, quote, the skulls
31:10
are entirely dissimilar and extraordinarily interesting.
31:12
True. It's kind of
31:14
hard to think of dinosaurs that
31:16
are more different than oviraptor and
31:18
Velociraptor. Yes. The
31:22
Velociraptor skull was found in
31:24
soft sandstone lying alongside a
31:26
protoceratops skull. It's
31:28
like a precursor to the fighting dinosaurs. Oh,
31:30
there was a protoceratops there, although I think
31:32
I said cetacosaurus earlier. You did. Osborne
31:35
described Velociraptor as a, quote, typical megalosaurian type,
31:37
because a lot of dinosaurs were thought to
31:40
be megalosaurs for a while. I didn't realize
31:42
that was still going on in the 1920s.
31:45
Yeah. It took a while.
31:47
Osborne also thought that the claw, the
31:49
sickle-like claw on the foot was on
31:51
its hand at first. But
31:54
then, John Ostrom recognized in
31:56
1969 that Velociraptor was closely
31:58
related to Dromaeosaurus Anacos and
32:01
assigned it to Dromaeosauridae. So
32:03
that's how it's known as a raptor. Well,
32:05
I guess it always had raptor in its name.
32:07
Yeah, because it was seizing whether or not it
32:09
was with its foot or its hands. It's
32:12
usually a good guess that if you have big
32:14
claws, they're on hands. There aren't
32:17
that many animals that have bigger, more impressive
32:19
claws on their feet. Right. Although,
32:21
was it Megaraptor where the opposite happened? Yeah, exactly. They
32:23
thought the big claw was on the foot, but it
32:25
was actually on the hand. Yeah, because it's got a
32:27
little bit of a similar shape to what Velociraptor has
32:30
going on. Yeah. In 2008, Pascal,
32:33
Godfroy, and others named
32:35
bones found in 1999 by the Sino-Belgian Dinosaur
32:39
Expeditions, they named
32:41
Velociraptor alsmolsky based on
32:43
a jawbone and part of the eye socket. Velociraptor
32:46
alsmolsky had robust teeth, a
32:49
tear drop shaped finestra or opening
32:51
near the snout, the
32:54
pro-maxillary finestra, that
32:56
was as large as the opening in the
32:58
maxillary finestra. But a 2013 study
33:01
found that the shape of the
33:03
jawbone was more similar to Linnharaptor,
33:06
so maybe Velociraptor alsmolsky isn't
33:08
Velociraptor and needs to be
33:10
reassessed. Yeah, that's always the
33:12
thing. When you have two different species
33:14
within a genus, there's a good chance
33:16
that as more dinosaurs get named, you're
33:19
going to find some that squeeze between
33:21
them that have different genus names. And
33:23
then one of those, I guess
33:26
the newer name for the species in the existing
33:28
genus is going to have to get split out,
33:30
which is what would happen here. Alsmolsky
33:32
would get split out into a new genus
33:35
and you'd just be left with Velociraptor mongoliensis.
33:37
Yes. You'd probably
33:39
still have something, alsmolsky. It
33:42
could be like Halskiraptor. Oh no, it
33:44
can't be. That already exists. That's
33:47
some other raptor. Lelsmolsky.
33:51
Well, we'll see what happens if it ever gets reassessed.
33:54
Multiple Velociraptor skeletons have been
33:56
found. One was found in 1995 at the
34:00
the flaming cliffs and it has a well-preserved
34:02
skull and body with limbs, missing only part
34:04
of the tail and ends of the long
34:06
bones, and there's some small elements
34:09
that probably happen from being scavenged. There
34:12
was a skeleton found in 1993, found in
34:14
a death pose with its legs tucked up
34:16
under the body. The skeleton
34:18
was eroded but parts of the skull, arms, ribs,
34:20
and vertebrae were found. And
34:22
based on this specimen, scientists found that
34:25
the big toe, the hallux, wasn't
34:27
reversed in raptors so we only see
34:29
this full reversal in archeopteryx and
34:32
some birds, including in antiornithines.
34:35
Dromaeosaur skeletons previously thought to belong
34:37
to Velociraptor have been renamed. One
34:40
was Ichabod Crayosaurus. It's
34:43
a skeleton without a
34:45
skull. That's how you got that nickname.
34:48
It was found in a 1990 joint Mongolian-American
34:50
expedition in the Gobi Desert. But
34:53
now that one is known as Sri Devai. It was named
34:55
in 2021. If
34:57
it sounds familiar, we talked about that in episode 328. It's
35:00
a cool one. I think I
35:03
was saying it's Sri Devai but
35:05
I'm not sure exactly. And I
35:07
think Ichabod Cray-nionsaurus was an
35:10
informal name, right? That's like in quotes. Oh
35:12
yeah, the nickname. Yeah. It's a
35:14
fun nickname. It would be pretty funny
35:17
if somebody officially named a dinosaur Ichabod
35:19
Cray-niosaurus because it was basically a skull.
35:21
Yeah. That would be pretty enjoyable.
35:23
That would be. In
35:26
2020, Mark Powers described a Velociraptor
35:28
specimen in his master's thesis, which
35:31
he found was a third new species
35:33
of Velociraptor based on having a shallow
35:35
jawbone. And later studies found
35:37
it to be distinct as well, but it
35:39
hasn't been named yet. So
35:42
we'll see how that goes. There might be some new
35:45
Velociraptor news. Yeah. Velociraptor
35:47
is, in addition to Jurassic
35:49
Park, famous for battling a
35:51
protoceratops in the fighting dinosaurs.
35:53
And that was found in
35:55
1971 by Zofia Kielin Javerowski
35:57
and a Polish-Mongolian team. One
36:00
of the coolest finds of all time by
36:02
far. Yes. Although, Dinachiras
36:04
is up there for me too.
36:06
Yeah. The fighting dinosaurs
36:09
probably were quickly buried in sand
36:11
from a sandstorm or collapsing dune.
36:14
The Velociraptor has a sickle-like claw on
36:16
the Protoceratops throat, and then the Protoceratops
36:18
beak is clamped onto the raptor's right
36:20
arm. So we don't know who was
36:22
winning. They both lost. Well, yes.
36:25
In the end, they both ended up fossils in the
36:28
middle of a fight. And
36:30
in the fighting dinosaurs, the Protoceratops was
36:32
much bulkier than Velociraptor, but
36:34
it was relatively small. It may have been a
36:37
juvenile. So it could be that there was an
36:39
adult Velociraptor trying to prey
36:41
on a juvenile Protoceratops. But
36:43
it's unclear if this happened a lot. The
36:45
fighting dinosaurs is the only direct fossil
36:48
evidence we have of two dinosaurs interacting,
36:50
at least so far. Well,
36:52
there's the dueling dinosaurs now.
36:56
That's currently being prepared, so we
36:58
don't know what to expect yet.
37:00
Yeah. How directly interacting they are.
37:02
Yes. I guess it depends how
37:04
you phrase it too, because we
37:06
have tooth marks that have healed
37:08
on dinosaurs and thagomizer holes that
37:11
seem to have healed slightly too.
37:13
So that's evidence of them interacting
37:15
too. Yeah, but not right in
37:17
the middle of a battle. It
37:20
might not count as direct fossil
37:22
evidence, like two animals literally interacting,
37:24
fossilized interacting together. Yes. Unless you
37:26
include a dinosaur sitting on a
37:29
clutch of eggs or
37:31
a dinosaur hanging out with others
37:33
of its same species fossilizing
37:36
together. Yeah. I'm not sure
37:38
how you define that. Yeah. If
37:40
you're a fan of the fighting dinosaurs, you probably
37:43
brush those to the side. Well,
37:45
with the fighting dinosaurs, it could have been
37:47
a chance encounter between the two of them
37:50
rather than a predator-prey interaction too. We
37:53
don't know. It's hard to say. We'll
37:56
get more into Velociraptor and how it
37:59
went out. after pray, so that
38:01
includes a sickle claw, in just a moment.
38:03

39:33
So at one point the sickle claw and
39:35
blast raptor was thought to disembowel prey, but
39:38
with the fighting dinosaurs, the
39:41
claws is on the throat of
39:43
protoceratops. So rather than going
39:45
for the bowels, like
39:48
stomach area, it seemed to go for
39:51
the jugular. Yeah. So
39:53
maybe velociraptor pierced vital parts of
39:55
the throat like the jugular or
39:57
windpipe. Oh yeah, that's true. windpipe
40:00
would also probably get the job
40:02
done. Yeah. A 2011
40:05
study by Denver Fowler and others suggested
40:07
the raptor prey restraint or the RPR
40:09
model. And that's what modern birds
40:11
of prey do. They proposed
40:13
this model after comparing raptor
40:15
feet and legs to modern birds of prey
40:17
like eagles and hawks. So
40:20
maybe Velociraptor used
40:23
the RPR where it leapt onto prey, pinned
40:25
it and held it with the sickle claws,
40:27
then would eat the prey and the prey
40:29
would die from organ failure and blood loss,
40:31
which sounds terrible. Yeah.
40:34
Yeah, animals aren't usually super interested in
40:36
killing their prey quickly as much as
40:38
they are in immobilizing it. Yeah.
40:41
This stabbing is also supported by how
40:43
Velociraptor was found with the fighting dinosaurs.
40:46
Velociraptor may have used its arms to help flap
40:48
and balance while on top of the struggling prey
40:50
and then the tail would have helped
40:52
with counterbalancing as well. You do
40:55
see that a lot with things like eagles
40:57
and hawks and other raptors as they use
40:59
their wings for that balance, sometimes like pressing
41:01
down to get better grip and things like
41:03
that. You can definitely see how that'd
41:05
be useful on Velociraptor even if it couldn't use its
41:07
wings to actually fly. Yes. Help
41:10
flap, keep it in place. It
41:12
also helped too because its jaws were relatively weak so
41:14
it had a weak bite. It
41:16
was estimated to have a bite force of 304 newtons and
41:19
that's lower than other Dromaeosaurids. Deinonychus
41:21
as an example had over 700
41:23
newtons. For the
41:25
record, 304 newtons is about 68 pounds
41:27
force if you need a comparison. Not
41:30
as strong as weak and bite but not
41:32
far off. Yeah. They had sharper teeth.
41:35
There was a study from 2024 earlier this
41:37
year that did find Velociraptor had a high
41:39
bite force compared to other raptors like Dromaeosaurus
41:42
and Deinonychus though. Seems
41:45
like bite force is a hard thing to estimate. That's
41:47
true. It's not a good thing to put
41:49
a lot of assumptions into your models when you're estimating bite forces.
41:52
Mm-hmm. In 2020, there
41:54
was a study that reconstructed the
41:56
endocranium of Velociraptor and
41:59
they compared it to non-85. Therapods, modern
42:01
birds, and other modern Arca-sores. They
42:04
found that Velociraptor Mongoliances could detect a
42:06
wide and high range of sound frequencies,
42:08
so it had good hearing. And it
42:10
was also agile and could probably track
42:12
its prey easily. So that
42:14
suggests that Velociraptor was an active predator that
42:17
would scavenge if the prey was older and
42:19
bad health, or maybe
42:21
during droughts or other prolonged climatic
42:23
events. The thinking is
42:25
that Velociraptor probably ate small mammals
42:27
and reptiles, and probably scavenged and
42:29
hunted, which a lot of
42:31
dinosaurs did, a lot of animals do.
42:33
Yeah, I'm a little bit surprised that
42:35
given their scavenging and some of their
42:38
adaptability, that none of these Velociraptor, you
42:40
know, basically flightless
42:42
bird-type dinosaurs survived the incretaceous
42:44
mass extinction. They seemed like
42:46
they were in pretty good
42:48
position for that. They're just
42:50
unlucky. Yeah. There's a
42:52
few scavenging examples of Velociraptor. There's
42:54
a 2010 study that found evidence
42:57
of Velociraptor feeding on protoceratops They
43:00
found bite marks on what was probably
43:02
protoceratops bones near some shed teeth that
43:04
were thought to belong to Velociraptor. They
43:07
found over 60 pieces of bone, including a
43:09
partial jaw and four teeth. The
43:11
teeth belonged to definitely a Velociraptorine based
43:14
on the shape of the teeth and
43:16
the size of the denticles, and the
43:18
only Velociraptor known from that time at
43:20
that area, which is the
43:23
Bayan Mandahu, is Velociraptor. At
43:25
least, that's what was known
43:27
until Lintaraptor was named also in 2010, but
43:29
the Lintaraptor paper came after this study was
43:31
published, even though they were published in the
43:34
same year. So they added a
43:36
note at the end of this 2010 study
43:38
that said Lintaraptor's description complicated their
43:40
referral of the teeth to Velociraptor,
43:43
but the poor condition of the known Lintaraptor teeth
43:45
made it hard to compare. And
43:47
they also said, well, there's also lots of Velociraptor
43:49
fossils in the area, so it still seems more
43:52
likely it belonged to Velociraptor. Yeah. That's
43:54
hard to say. Yes. And also you get
43:56
that thing where even
43:58
though you might say... Well, there's
44:01
such similar animals, maybe they both
44:03
hunted protoceratops. You get
44:05
that niche partitioning where sometimes there's two very
44:07
similar looking species and they do pretty different
44:09
things. Yes. The teeth, we
44:12
do know, they were small, were curved and
44:14
serrated. And the pattern of
44:16
bite marks are similar to other tooth marks from
44:18
theropop bites, which were interpreted
44:20
as accidental marks made while feeding,
44:22
so not deliberate bone biting. Just
44:25
kind of scraping them while it was eating. One
44:28
tooth was broken. Velociraptor skull
44:30
and teeth don't seem like it'd be
44:33
able to eat bone and they're small
44:35
compared to protoceratops. So
44:37
the bite marks on the jaw bone might show that
44:40
this animal was eaten at a
44:42
late stage because the taste of your bits
44:44
are in the legs or the abdomen area. Yeah,
44:47
typically, like if you go to the butcher
44:49
and you get a slice of cow,
44:52
you don't ask for the jaw meat. Pretty
44:55
far down the list. That's true. You
44:59
get that. Those are the animals that are scavenging. They
45:01
get that usually. There were also a
45:03
lot of bite marks on this animal, which might mean
45:05
that a lot of the meat was already stripped off
45:07
and the raptor was eating close to the bone. It's
45:11
possible there was a group hunting or
45:13
feeding situation, because it doesn't seem likely
45:15
that a single Velociraptor, even an adult
45:17
could eat all the flesh of an
45:19
adult protoceratops in one sitting, and
45:21
that protoceratops was about adult sized. However,
45:25
the fact that there's only two shed
45:27
crowns may mean that there was just one scavenging
45:29
individual and not a group of predators. Oh,
45:31
I see. Because it wasn't just like a whole
45:33
field of Velociraptor teeth scattered everywhere
45:36
where it looked like a whole bunch of
45:38
a protruding on it. Just a
45:40
couple. So the scavenging also might be
45:43
more likely for the late stage feeding. Either
45:46
way, this study supports the idea that
45:48
Velociraptor, if it is in fact Velociraptor,
45:50
which it seems likely, is
45:53
a great protoceratops either has prey or it's
45:55
scavenged it. It's always so hard to know.
45:57
Especially in cases like this, you don't know if maybe there
45:59
were. a whole bunch of teeth and just
46:01
only a few of them fossilized. Yeah. There's
46:04
no evidence for velociraptor hunting in packs, but
46:06
there are raptor trackways that may show they
46:08
walk together. So they suggested
46:10
that either way, velociraptor feeding on
46:12
protoceratops was probably relatively common. We
46:15
have two good pieces of evidence already. It's
46:18
more than we have for a lot of other dinosaurs.
46:20
Yeah, seriously. In 2012, David Hohn
46:22
and others described a pterosaur long bone, a
46:24
leg or arm bone, that was
46:27
found in the gut contents of a velociraptor.
46:29
The pterosaur would have been too big
46:31
and dangerous for velociraptor when it was
46:34
alive, so it seems likely that the
46:36
velociraptor scavenged it. This velociraptor was
46:38
largely complete and articulated. It was only missing
46:40
its right arm and most of the tail.
46:42
And it looked like it was injured when
46:44
it died because there's one broken rib that
46:46
showed signs of regrowth. So it was either
46:48
injured or recovering from an injury. And it
46:51
was a young sub-adult individual. Part
46:54
of the pterosaur bone was in the velociraptor's
46:56
chest cavity, and it
46:58
belonged to an ajdarkid pterosaur,
47:01
which is the group with
47:03
some of the largest pterosaurs, if you think Hazzagopteryx
47:06
and Quetzalcoatlus. Yeah. And
47:08
then you compare that to the size of a
47:10
velociraptor and you think, yeah, scavenging seems like the
47:13
way to go here. Yeah, it seems more likely.
47:15
There's narrow spaces between the velociraptor's ribs,
47:18
so it was probably digested and probably
47:20
didn't just end up in
47:23
that cavity after the dinosaur died. Yeah,
47:25
because if its ribs are more or
47:27
less intact, there isn't an easy way
47:29
for that bone to get pushed
47:32
in there by water or something,
47:34
moving the bones around after
47:37
everything's fossilizing. But
47:39
it might not have been in its gut for
47:41
very long because the surface of the bone is
47:43
smooth. There's no signs of digestive acids. The
47:46
edges are broken and jagged and rough, which
47:49
may mean it was broken before or as
47:51
part of it being ingested. But
47:53
the rough edges not being smoothed out
47:56
may mean that the bone just wasn't
47:58
long in the gut. Yeah, usually you
48:00
get that acid. etching pretty quickly. Yeah.
48:02
So you would think this must have
48:04
died very shortly after swallowing it. Yep.
48:06
Maybe because of swallowing it. Oh no,
48:08
it choked on it. Maybe. Maybe. So
48:10
going back to why this was a
48:12
scavenging thing, that Velociraptor specimens estimated to
48:14
weigh 13 kilograms versus
48:17
pterosaurs that had large wingspans. So
48:19
they would have been dangerous unless
48:21
it was already sick or injured.
48:24
The Velociraptor probably ate the bone because
48:26
there wasn't much meat left on the
48:28
carcass, unless it needed the minerals. Yeah,
48:30
that's true. If it was laying some
48:32
eggs. Yeah. And large bones being
48:34
swallowed whole is not common, but it happens
48:36
when there's no alternative. So it's
48:38
probably challenging to eat. And yeah, like you said,
48:40
maybe it didn't choke on it. Yeah. One
48:44
more example of a Velociraptor specimen found was in
48:46
1985, Norrell and others found
48:48
a skull with two rows of small
48:51
punctures on it that matched the size
48:53
and spacing of Velociraptor teeth. So
48:56
those punctures might've been from another Velociraptor.
48:59
There's no signs of healing and the
49:01
specimen wasn't scavenged. So it probably died
49:03
from its wound. Interesting.
49:05
I wonder how they know it wasn't scavenged. There
49:08
must've been other evidence. Yeah. Must be the way the
49:10
skull looked. No scrape marks. Just
49:14
got straight up murdered. Maybe there
49:16
was a fight. Yeah.
49:18
Really hard to say. Velociraptor
49:21
lived in a semi-arid climate
49:24
with sand dunes and intermittent
49:26
streams. Some other dinosaurs that
49:28
lived around the same time and place included
49:30
in kylosaurs like panakasaurus, alvarosaurs
49:32
like lintanicus, protoceratopsids
49:34
like protoceratops, of course, troodontids
49:38
like linta venator, and
49:41
the dromaeosaur lintaraptor. And
49:43
some other animals that lived around the same
49:45
time and place included crocodiles, small lizards, and
49:47
mammals. And a lot of the
49:49
animals that have been found in the formations were
49:51
found in situ and they probably died during sandstorms.
49:54
Yeah. I've heard it described that
49:56
Mongolia in the Mesozoic, the
49:58
latest Mesozoic when a lot of the stuff
50:00
fossilized, was pretty similar to Mongolia
50:02
now, Sandy. Very
50:05
good for digging up fossils. Yeah,
50:07
and preparing the fossils. And
50:11
our fun fact is
50:13
that paleobiologist, Zofia Keelan
50:16
Yavaroski, not only
50:18
found the fighting dinosaurs, but
50:20
she also discovered dinochirus and
50:22
gallimimus. It took two
50:24
days to excavate dinochirus and load onto
50:26
a vehicle. They found
50:28
those gigantic arms, much later
50:31
than Velociraptor was named, they found them in 1965. And
50:35
it presented a mystery, because gallimimus
50:37
was the arm, so was it so ferocious
50:39
it could tear apart prey with its hands?
50:42
And it took about 50 years to find the answer,
50:44
and it was an unexpected answer, because dinochirus
50:46
was almost goofy. I
50:49
think we've put it before, Garrett, its giant
50:51
arms were more like salad tongs to scoop
50:54
up food, both plants and fish. The
50:57
year before that, in 1964, Zofia
50:59
found the largest skeleton and
51:02
holotype of gallimimus, the chicken
51:04
mimic theropod. It was
51:06
large with a small head, it had a beacon feathers,
51:08
it could run really fast. The skeleton
51:10
was found lying on its back and the skull was
51:12
under its pelvis. Zofia was
51:15
a Polish paleobiologist. She led a series
51:17
of expeditions to the Gobi Desert. Her
51:20
work didn't just include dinosaurs though, she had
51:22
a big influence on the origins and early
51:25
evolution of mammals. And she also
51:27
studied trilobites and she published a ton
51:29
of scientific articles and books. She
51:32
was born in Poland in 1925, she
51:34
lived through World War II, and she
51:37
accomplished a lot. Among her
51:39
many achievements, she was the first woman to
51:41
serve on the committee of the International Union
51:43
of Geological Sciences. We
51:45
will be doing a whole episode on her coming
