Pistosaurus is a genus of marine sauropterygian reptiles. It is a Nothosaur, a relative of the plesiosaurs.
Pistosaurus was a advanced nothosaur-like body with a plesiosaur-like head. Is presently known only from the Middle Triassic. Even if it is a nothosaur it is acknowledged to be closely related to the ancestors of plesiosaurs.
The head also resembled that of a plesiosaur, but with the primitive palate[1] of a nothosaur, and numerous, sharp teeth ideal for catching and eating fish.[2]
Although it is unlikely that Pistosaurus was a direct ancestor of the plesiosaurs, the mixture of features suggests that it was closely related to that group.[2]
