These are carnotaurs, which I'm told were in the Disney movie Dinosaur. I never saw that one, but it did use Lords Of Acid's "The Crablouse" in its trailer, which I found to be pretty fucking hilarious. (They used an instrumental, of course, considering the song's immortal lyrics: Here's a message to the girls about vaginas / and the consequence of fiddling with a partner / Mind your labia, they're never out of danger / if you choose to go to bed with a stranger.)
