(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.
The Plesiosaurus could grow to about 3 to 4 meters in length. Its weight is debatable, but is estimated at about 150 to 350 pounds. This size was small as compared to some of the late Jurassic and early Cretaceous plesiosaurs such as the Kronosaurus which attained a length of over 10 meters.
