Champsosaurus was a choristoderan that lived from the Late Cretaceous to the Eocene in what is now North America and Europe. They were not very large but they were fairly successful.

It grew to about 1.50 m (5 ft) long, though C. gigas, the largest species, reached 3-3.5 m (10–12 ft).

Champsosaurus vaguely resembled a gharial and, like gharials, it was primarily aquatic, catching fish with its long, tooth-lined jaws. It probably swam with lateral body movements, pinning its limbs against its body to increase its streamline, just like crocodiles and the marine iguana. It was so specialised to life in the water that only females could come ashore to lay eggs, while males could not move on land.

Behind the eyes, Champsosaurus's skull was very wide, where powerful jaw muscles were attached.

Its fossils have been found in North America (Alberta, Saskatchewan, Montana, New Mexico, Texas, and Wyoming) and Europe (Belgium and France), dating from the Upper Cretaceous to the mid Eocene. Possible Champsosaurus teeth have been found in East Timor, making them exceptional in being the only gondwannan and australasian choristoderes known.

In Saurian Edit

Champsosaurus is slated to appear in Saurian. It is portrayed with thick scales and small spines. Its' color is olive green with yellow spots, black spines and a white underbelly to match its' habitat.
