With its two crests on its head and a protruding overbite, Dilophosaurus confidently strutted around the northern regions of Arizona 193 million years ago. Dilophosaurus was first discovered back in 1940 by the Navajo Indians but was not thoroughly scientifically studied until much later. As a result, it has been subject to various speculative reconstructions in films and popular culture. It was once believed that its jaws were weak, suggesting it may have been a scavenger or fish eater, or that it used venom to hunt. However, recent research shows that Dilophosaurus had a powerful bite and most likely sprinted through the river landscape in pursuit of enormous prey, such as the long-necked Sarahsaurus. Dilophosaurus was indeed a dinosaur killer and a top predator in the early Jurassic period.
