Jurassic Period. The name means 'two-crested lizard', from the two crests of the animal (Greek di meaning 'two', lophos meaning 'crest' and sauros meaning 'lizard'). The first specimens were described in 1954, but it was not until over a decade later that the genus received its current name. Dilophosaurus is one of the earliest known Jurassic theropods, but also one of the least understood.
Popular Culture Edit
- The 1993 film Jurassic Park features an inaccurate dilophosaurus that spits venom, has a frill and is tiny, though the later is because it didn't want to be confused with Velociraptors, enlarged in the film.
Video Games Edit
- The Ice Age 3: Dawn of the Dinosaurs game features that spit venom and have a frill.
