(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.
How long Plesiosaurus spent in the water has long been a matter of debate.â­ â¬Classical art and reconstructions from the early years of marine reptile palaeontology depicted it as being just as capable of walking about on land as it could swim in the ocean.â­ â¬Also the long neck was almost always depicted as shooting out from the water and arcing around in strong curves,â­ â¬but today both of these depictions are thought to be highly unlikely.
