Dilophosaurus [SEP] Introduction
Due to the limited range of movement and shortness of the fore limbs, the mouth may instead have made first contact with prey. The function of the crests is unknown; they were too weak for battle, but may have been used in visual display, such as species recognition and sexual selection. It may have grown rapidly, attaining a growth rate of per year early in life. The holotype specimen had multiple paleopathologies, including healed injuries and signs of a developmental anomaly. "Dilophosaurus" is known from the Kayenta Formation, and lived alongside dinosaurs such as "Megapnosaurus" and "Sarahsaurus". "Dilophosaurus" was featured in the novel "Jurassic Park" and its movie adaptation, wherein it was given the fictional abilities to spit venom and expand a neck frill, as well as being smaller than the real animal.
