Dilophosaurus

Dilophosaurus was a coelophysid from the early Jurassic. In Jurassic Park, Dilophosaurus had frills and could spit venom to blind prey. Dilophosaurus would be different than that in real life, having no frills, cannot spit venom and has a longer neck. It was 6 metres long, as big as Utahraptor, making it the biggest coelophysid. however it could not be a coelophysid and make its own family, the dilophosaurs.
