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
04:00you
04:02you
