(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.
Plesiosaurs were one of the first kinds of extinct animal known to science, and were described as early as 1821. The smallest were about 2m long as adults, the largest were enormous pliosaurs up to 20m long, comparable in size or even bigger than sperm whales (Physeter).
