Dilophosaurus

Group of Species

Dilophosaurus is a genus of theropod dinosaur that lived in what is now North America during the Early Jurassic Period, about 193 million years ago. In 1940 three skeletons were found in northern Arizona. The two most complete of these were collected in 1942, with the most complete later made the holotype specimen of a new species of the genus Megalosaurus, named M. wetherilli by Samuel Welles in 1954. Welles found a larger skeleton belonging to the same species in 1964. Realizing it bore crests on its skull, he moved the species to the new genus Dilophosaurus in 1970, as D. wetherilli. The genus name means "two-crested lizard", and the species name honors John Wetherill, a Navajo councilor. More specimens have since been found, including an infant, and footprints have also been attributed to the animal. Another species from China, D. sinensis, was named in 1993, but was later found to belong to the genus Sinosaurus.
