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. While known Dilophosaurs are unlikely to have possessed a frill, the specimens at Jurassic Park may in fact represent a subspecies not previously known to science. The same or a similar species were encountered by former Navy Seal Craig Dylan after being lost within the Bermuda Triangle during a completely unrelated incident. Dilophosaurus has been found in both the U.S. and China, which, although part of the same huge landmass, were still quite a long distance from each other. There is also no evidence of venom in the known subspecies of the dinosaur's systems.
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. It also had a long tail that could have been used as a whip in a fight. Footprints attributed to Dilophosaurus appear in groups, so it may have hunted in small packs.
Dilophosaurus lived during the early Jurassic Period, before mosquitoes are currently confirmed by the fossil record to exist. If Jurassic Park was able to find any viable DNA specimens, there would have been very little to go on. This would mean that there would be more gaps than normal in the DNA sequence, subsequently filled by more frog DNA. This could explain why the Dilophosaurus are so different from their prehistoric counterparts, far more so than other dinosaurs.
