Dilophosaurus was one of the largest carnivorous dinosaurs of the Early Jurassic Period. Dilophosaurus gets its name from the two thin crests of bone on the top of its head. These were probably used as a display for courtship purposes. (Its frill and ability to spit venom at its prey is actually made up and no there is no proof if it had such abilities) Dilophosaurus has been found in Northern Arizona.
As a more primitive predatory dinosaur, Dilophosaurus didn't have forward facing eyes to give it stereo vision. It may have used scent as an integral part of its hunting technique. It had long and slender, rear-curving teeth in long jaws and strong front arms which would have been effective in grabbing prey. It was fast - probably with a top speed of about 30-mph. Footprints attributed to Dilophosaurus appear in groups, so it may have hunted in small packs. It shares the same overall body configuration as Coelophysis even though Dilophosaurus is currently classified as a member of a different group of theropods rather than Coelophysis and its relatives.[4]
