Dilophosaurus

Dilophosaurus was a meat-eating dinosaur that roamed North America 186 million years ago. It stood out with its distinctive double crests on its head, which likely made it look striking. Paleontologists first found its bones in Arizona, where several well-preserved skeletons helped reveal its unique features.

• Had twin crests on its skull, giving it the name 'two-crested lizard'.
• First discovered in 1940, with the best specimens collected in 1942.
• Fossil footprints suggest it left behind traces of its resting spots.
