The flesh-eating Carnotaurs from Dinosaur may not have been as scary as Jurassic Parks T-rex, but they still proved to be formidable villains, and made children appreciate the extinction of dinos all those millions of years ago. Known to palaeontologists as Carnotaurus (Latin for meat-eating bull), they were portrayed as larger and faster than what fossils suggested, which made them even more harrowing. With horns like a bull (hence the name) and massive jaws with a wicked set of teeth, Carnotaurs like to bite first and ask questions later. The hero dinosaurs of the film only have two options: run, or band together and make a stand. The opening scene of the film shows a Carnotaur ambushing a herd of dinosaurs and taking one down. This sets them up as the top predator of this prehistoric world from the very beginning. Though the carnage they are capable of isnt explicitly shown, the CGI used to bring them roaring to life is near flawless, and their presence is enough to send chills down the spines of the biggest childhood dinosaur enthusiasts.
