Sotheby's unveils the only known juvenile skeleton of a carnivorous dinosaur, the Ceratosaurus  A rare juvenile Ceratosaurus skeleton — the first and only young example of the Late Jurassic carnivore ever found — will lead Sotheby’s Natural History sale in New York on July 16.  "This is one of only four known Ceratosaurus in the world. And of those four, this is the only juvenile," said Cassandra Hatton, Sotheby’s vice-chairman and global head of science and natural history, noting that juvenile fossils rarely survive the rigors of deep time.  Hatton added that the specimen’s skull offers exceptional research value: "It’s incredibly rare to find a complete skull."  The specimen was unearthed in 1996 at the Bone Cabin Quarry in Wyoming and had previously been exhibited in unmounted form at the Museum of Ancient Life in Utah. It is the second most complete Ceratosaurus ever discovered, after the original holotype at the Smithsonian National Museum of Natural History.

00:00This is one of only four known ceratosaurus in the world and of those

00:29four.

00:30This is the only juvenile, and that's a major find.

00:35Any juvenile dinosaur is super important, super rare.

00:40Their fragile bones rarely survive the fossilization process or rarely survive being eaten by another

00:49dinosaur.

00:50Baby dinosaurs were particularly tempting to other adult dinosaurs, so it's just not

00:56something that you find fossilized.

00:59And they're so important scientifically because they allow us to see how dinosaurs grow.

01:06You compare the skull, you compare other parts of the anatomy, we understand the types of

01:12changes that they undergo through their lifetime.

01:14It's incredibly rare to find a complete skull, all of the little fine, fine bones are present,

01:29and it was found disarticulated, which is really important.

01:48Some skulls you'll find are found fossilized in one block, but all of the pieces were disarticulated,

01:55and that means that you can actually take them off the mount and study each one individually.

02:01So scientifically, it's really important to have a skull like that because you can study

02:06it.

02:07also you can study it and compare those things and prepare them all.

02:10know but they're all individual themselves so you can see because you can probably

02:15have a curve to resolvive.

02:16so it's really, like you do well and that don't look at the hell.

02:19you could all the and your ability to use that and I'm very proud of you.

02:25So again, the great thing is that, we were able to see that every generation, but what we

02:35on ceratosaurus versus other theropods and even humans is when you're looking at bones you'll

02:50usually see a flat bone surface cartilage and another flat bone surface on ceratosaurus you

02:57actually see a socket so those pelvic elements fit into a socket on the ilia and the ischium so that

03:06that is a diagnostic feature of ceratosaurus that we don't see on other dinosaurs so the skull has

03:14features that tell us right away it's ceratosaurus you've got the horn on the nose being the the big

03:20red flag here i am i'm ceratosaurus but if we didn't have that we would still be able to know

03:25that it was a ceratosaurus from this really interesting feature in the the pelvis

03:55so
