Polycotylus plesiosaur, illustration. Plesiosaurs were marine reptile predators, feeding mainly on fish. They breathed air, like modern turtles, and may have returned to beaches to lay their eggs. Polycotylus plesiosaurs lived during the Late Cretaceous (100 to 65 million years ago) in what is now North America. They reached up to 5 metres in length. | |
