Dilophosaurus sound effects. What science has revealed about the biology of Dilophosaurus might not be quite so dramatic, but we still have many neat insights into this dinosaur’s life, and it continues to provide mysteries for paleontologists to solve. It was slender and lightly built, and the skull was proportionally large, but delicate. It was one of the largest carnivores of its time. One of the largest predatory dinosaurs of North America of the time, Dilophosaurus is known for the distinctive paired crests on its head. It is known primarily from the Kayenta Formation in what is now the southwestern United States. Known for its head crests, the Dilophosaurus lived during the early Jurassic period over 190 million years ago. Many fiction and fantasy films, novels, and books depict them, and a computer game character has even been created. Dilophosaurus was a meat-eating dinosaur that lived in what's now North America. Dilophosaurus means “double-crested lizard” in Greek, a name that refers to its headgear. It is known by a single known species Dilophosaurus wetherilli. gxbf ixixx orfklsn rwafp gdezs wxsby jjuhn rlmkt ugyyxg easxd
