Dilophosaurus

Dilophosaurus ( /daɪˌlɒfɵˈsɔrəs/ dy-LOF-o-SAWR-əs or /daɪˌloʊfɵˈsɔrəs/; Greek: di for "two", lophos "crest", and sauros "lizard") was a theropod dinosaur from the Sinemurian stage of the Early Jurassic Period, 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. It is one of the earliest known Jurassic theropods and one of the least understood.

Dilophosaurus has appeared several times in popular culture, such as in the 1993 film Jurassic Park.
