The Dilophosaurus is a real Early Jurassic theropod, but most people know it from Jurassic Park, where it was reimagined as a frilled, venom-spitting predator with a memorable rattling cry. That film version shaped how games, documentaries and memes portray the animal ever since. Clips of its hiss and chirp circulate as shorthand for a clever ambush predator, and creators keep reusing the sound because it reads instantly as dinosaur without needing the bulk of a T. rex roar.
