Pliosaurus was a genus of pliosaur from the Mid-Late Jurassic Period that once swam the seas of Western Europe. Pliosaurus has the typical look: Short neck, long, large jaws, and a four-flipper body. Discovered in 1840, Pliosaurus is known from the Kimmeridge Stage (Late Jurassic) where it was likely top predator. Pliosaurus and Liopleurodon are fairly similar and there are often species moved from one genus to another. Pliosaurus can be distinguished from Liopleurodon by its symphasis length: Pliosaurus has a long symphasis joining the rest of the jaw after 12 tooth positions, where as Liopleurodon's symphasis joins after only about 6 tooth positions. Atypical of mot pliosaurus, the cross-sections of Pliosaurus's teeth were trihedral. Like most pliosaurs, Pliosaurus had a short neck and a large skull. Its bulk was propelled through the sea by four gigantic paddle-like flippers. Pliosaurus was among the largest of all marine reptiles. The largest, P. funkei, has been estimated between 10.0–12.8 meters (32.8–42.0 ft) in length.
