Plesiosaurus was an extinct genus of marine sauropterygian reptiles that lived during the Jurassic Period. The type species of this genus is Plesiosaurus dolichodeirus. Skeletons are found in Europe.

Pleisiosaurus is distinguished by its small head, short snout, long and slender neck, broad turtle-like body, a short tail with a fluke at the end, and two pairs of large, elongated paddles. Plesiosaurus fed on belemnites, fish, and other prey.

Some traces of skin impressions discovered suggest that it had smooth skin, rather than scaly skin.

The Plesiosaur Pond was an attraction originally meant to appear in Jurassic World but was cut from the final film. It was to be a large pool like the Jurassic World Lagoon inhabitated by Plesiosaurus and several unidentified species of ichthyosaurs. Visitors to Jurassic World would be able to visit the attraction by boarding a submarine attached to a monorail.[2]
