Himalayasaurus
''Himalayasaurus'' is an extinct genus of ichthyosaur from the Late Triassic of Tibet. The type species ''Himalayasaurus tibetensis'' was described in 1972 on the basis of fragmentary remains, including teeth, limb bones, and vertebrae. The entire body length of ''Himalayasaurus'' is estimated to have been over in length. ''Himalayasaurus'' has since been considered a ''nomen dubium'' or "dubious name" because of the lack of features that set it apart from other ichthyosaurs, although the presence of distinct cutting edges on its teeth have more recently been proposed as a unique feature of the genus (cutting edges have also been found in the recently described ichthyosaur ''Thalattoarchon'' from the western United States). ''Himalayasaurus'' belongs to the family Shastasauridae, which includes other large-bodied Triassic ichthyosaurs like ''Shonisaurus''.〔
