Prehistoric Models: Nothosaurs

Nothosaurs are members of an extinct order of marine reptile classified as Sauropterygians, related to plesiosaurs and pliosaurs. With a diet of fish and squids, they had a very similar lifestyles to modern seals, marine with the ability come ashore. It is believed that nothosaur-like reptiles were ancestral to the more completely marine plesiosaurs, which replaced them at the end of the Triassic Period.
