Baryonyx

Baryonyx was a large predator like T-Rex in the Early Cretaceous period. It ate fish more than meat. The huge crocodile like jaws could rip apart a fish. It also had a big, hooked claw on its hand.

Corythosaurus

Corythosaurus lived North America. It was a duck-billed dinosaur and had a head-crest. They probably used it to attract a mate and communicate. The low trumpeting sound was made by nasal passages in its crest.
