Dinosaurs: Dilophosaurus

 

Dilophosaurus (Two-Ridge Lizard)

Dilophosaurus was a large meat-eater dinosaur that lived during the early Jurassic. Unlike those portrayed in the movies, Dilophosaurus was one of the largest predators of the early Jurassic reaching lengths of 20ft (6m) and weighing up to 1000 pounds (450 kg)

Dilophosaurus gets its name due to two thin crests of bone on the top of its head. These were probably used as a display to attract mates.

Unlike later meat-eating dinosaurs, Dilophosaurus did not have forward facing eyes to give it stereo vision. Scientists believe that it may have used scent to locate its prey. It had a kinked upper jaw with a gap between its front and back teeth. Dilophosaurus also had strong front arms which would have been effective in grabbing its prey.

Fossilised footprints evidence suggest that Dilophosaurus may have hunted in packs.
