Chasmatosaurus by Moondawg

Chasmatosaurus is an extinct genus of archosauriform reptile that grew about 4 m (12 ft 8 in) long from the Early Triassic of China.

Also called Proterosuchus, Chasmatosaurus was a crocodile-like creature that probably hunted like its extant descendants, attacking drinking prey on the waterside. Its upper jaw arched down at the front, and the creature had teeth on its palate- a primitive trait. it had a main cameo in walking with monsters attacking a herd of lystrosaurus. it is a possibility that chasmatosaurus is an ancestor of crocodillians.
