PLIOSAUR
(pronounced PLY-oh-SAWR) Pliosaurs (meaning "greater lizard") were huge, short-necked plesiosaurs. These flippered marine reptiles were carnivores with sharp teeth in large, powerful jaws. They may have eaten ichthyosaurs and other plesiosaurs. They lived during the Jurassic and Cretaceous periods and they were not dinosaurs. Some Pliosaurs include Peloneustes, Macroplata, Kronosaurus, and Liopleurodon.
