(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.
According the the documentation that went with the specimen, the remains were nearly complete, lacking some cervical vertebrae and the skull. This is a picture of the more than 240 gastroliths (stomach stones) found associated with the above plesiosaur remains by George Sternberg. The largest stone measured 79 x 57 x 28 mm and the total weight of the gastroliths was 2.2 kg.
