(See a gallery of plesiosaur and pliosaur pictures.) Plesiosaurs (Greek for almost lizards) were large, long-necked, four-flippered marine reptiles that paddled their way through the oceans, lakes, rivers and swamps of the Jurassic and Cretaceous periods.
They ate fish, squids, mollusks and other small sea creatures. Recently, scientists have found evidence that the Plesiosaurs may have also been bottom-feeders. That is they would feed from the bottom of the sea-on things like clams and snails.
