Plesiosaurs (PLEE-see-oh-SORES) were large, carnivorous aquatic reptiles. They are somewhat fancifully said to look like "a turtle with a snake threaded through its body", though they lacked a shell.

They first appeared in the late Triassic period and thrived until the K-T extinction at the end of the Cretaceous. Despite being large Mesozoic reptiles, they were not a type of dinosaur.

It is occasionally claimed that plesiosaurs are not extinct, although there is no scientific evidence for this belief; the modern sightings that are occasionally reported are usually explained as basking shark carcasses or hoaxes.
