Mauisaurus
''Mauisaurus'' ("Maui reptile") is a genus of plesiosaur that lived during the Late Cretaceous period around 80 to 69 million years ago in what is now New Zealand. It was the largest plesiosaur, and perhaps the largest marine reptile in New Zealand waters at the time. ''Mauisaurus haasti'' is the only known species of the genus. A handful of specimens have been found, although only a few are well preserved and mostly complete. The only other established New Zealand plesiosaur, ''Tuarangisaurus keyesi'', cannot be linked as a direct relative to ''Mauisaurus''.
==Description==
At 68 cervical vertebrae, ''Mauisaurus'' is notable for having one of the longest necks (in terms of vertebra number) of any plesiosaur. ''Mauisaurus'' was fairly large, reaching over in length.〔Hiller, N., Mannering, A.A., Jones, C.M., Cruickshank, A.R.I. (2005). The nature of ''Mauisaurus haasti'' Hector, 1874 (Reptilia: Plesiosauria). ''Journal of Vertebrate Paleontology'' 25 (3):588-601.〕 Like other plesiosaurs, it had a long slender body, with numerous vertebrae, allowing flexible movement. On its underside, ''Mauisaurus'' had two sets of large flippers. These aided in swimming at high speeds, but may have also allowed the plesiosaur to venture onto shorelines for short amounts of time. ''Mauisaurus'' was a carnivore, with sharp jagged teeth that would have been used to grip fish or squid.
