shyt had me shook as a youth tho..:wow:



Dilophosaurus is prominently featured in both Michael Crichton's 1990 novel Jurassic Park and its 1993 movie adaptation. It is depicted spitting blinding poison, aiming for the eyes to blind and paralyze its prey (much like a spitting cobra); in the film, it also has a retractableneck frill around its neck (much like a frill-necked lizard). There is no evidence to support either the frill or the venom spitting,[54] which was acknowledged by Crichton as creative license.[55] In the film, Steven Spielberg also reduced the size of Dilophosaurus to 3 feet (0.91 m) tall and 5 feet (1.5 m) long in order to avoid confusion with the velociraptors

Dilophosaurus (/daɪˌlɒfɵˈsɔrəs/dy-lof-o-sawr-əs or /daɪˌloʊfɵˈsɔrəs/); is a genus oftheropoddinosaur from the Sinemurian stage of the Early JurassicPeriod, about 193 million years ago. The first specimens were described in 1954, but it was not until over a decade later that the genus received its current name."

"The crests on the skull of Dilophosaurus are considered to be cranial ornamentation for use in attracting mates. Padian, Horner and Dhaliwal (2004) challenged conventional hypotheses that the purpose of bizarre cranial structures and post-cranial armor in dinosaurs, was either for attracting mates, intimidating/fighting rivals in the group, or intimidating potential predators of other species. Padian et al. noted that based on phylogenetic, histological, and functional evidence these bizarre structures can be explained by the phenomenon ofintra-species recognition, which is supported by the fossil evidence."
