The Dilophosaurus had a large crest on its skull, made from delicate bone. This crest wasn’t strong enough to be a weapon, but was probably used to intimidate or impress. Because it was one of the largest animals alive during its time, its short, curved teeth were probably just right since it wasn’t hunting large prey.

Questions and Answers

Question: Is Dilophosaurus a well-known dinosaur?

Answer: It became more well-known after it was featured in the first Jurassic Park movie. It was portrayed inaccurately in the movie though. It didn’t have a large fringe around its neck, and it probably couldn’t spit venom.
