Peloneustes philarchus

Peloneustes philarchus is a species of fossil marine reptile known from the Middle Jurassic (164.7-161.2 million years ago) of the UK. 

Peloneustes philarchus is the most common species of fossil pliosaurid from the UK, and probably the best known pliosaurid species in the world due to the relatively large number of specimens held in museum collections.

Peloneustes philarchus belongs to a family of plesiosaurs called Pliosauridae, of which there are at least nine 9 species known from around the world, from the Middle Jurassic to the Upper Cretaceous.

Species detail

Peloneustes philarchus had a stream-lined body and large hydrofoil-like flippers that it used to swim through the water. This suggests a strictly aquatic lifestyle. It is unlikely Peloneustes philarchus  could venture onto land.
