Dilophosaurus was one of the larger theropod predators of the Jurassic era. Its name means 'double-crested lizard' in reference to the two crests upon its skull. As an early predator it lacked forward-facing eyes, so would likely have relied on scent rather than vision for hunting.
Discovery
The first Dilophosaurus specimens were discovered in the Kayenta Formation in Arizona, USA in 1942. So far only one confirmed species has been found.
Paleoecology
The Kayenta Formation was once a silt-rich river basin with slow-moving water. It supported abundant animal and plant life.
