Styxosaurus
''Styxosaurus'' is a genus of plesiosaur of the family Elasmosauridae. ''Styxosaurus'' lived during the Santonian and Campanian ages of the Cretaceous period. ==Description== ''Styxosaurus'' was a large plesiosaur, one of several species of a group collectively called elasmosaurs that appeared in the Late Cretaceous. Elasmosaurs typically have a neck that is at least half the length of the body, and composed of 60-72 vertebrae. ''Styxosaurus'' was around 11 meters (36 ft) to 12 meters (40 ft) long, with about half of the length being neck.〔(【引用サイトリンク】title= National Geiographic "Styxosaurus" )〕 Its sharp teeth were conical and evolved to puncture and hold rather than to cut, for, like other plesiosaurs, ''Styxosaurus'' swallowed its food whole.〔
