Take a bite out of the weekend with Dilophosaurus wetherilli, a carnivorous dinosaur that lived some 194 million years ago during the Early Jurassic. This dino acquired its name, which means “double-crested reptile,” from the paired crests on its skull—which were possibly used for display. This specimen was found in 1942 at the Kayenta Formation in Tuba City, Arizona. You can see it in the Museum’s Hall of Saurischian Dinosaurs! Photo: M.
