Dilophosaurus

Dilophosaurus ("two-crested lizard") was a swift predator from the Early Jurassic. Mostly know from the movie Jurassic Park, in which it was incorrectly portrayed with a frill and venom-spitting.

Iberomesornis's Idea
Dilophosaurus should have ton of space to run and jump. Dilophosaurus should come in packs of 3 or 4. The exhibit should be coast-like, with carrion and fish to eat; the jaws were too fragile. Palm trees, molusks, limestone and even worms would provide a nice ambient, and replicate the enviroment of Kayenta. The "dilos" should have shadow in forms of big ferns, palmtrees and bushes.
