The Dilophosaurus was a predatory dinosaur that lived approximately 190 million years ago during the Early Jurassic in what is now North America. One of its more distinctive features are a pair of crests found on its skull that may have been used for visual display. While it was one of the larger early predators (at 6m length and 300kg) it is smaller than later theropods such as the Tyrannosaurus. The first recorded discovery of a Dilophosaurus fossil was in 1940.
