Nectosaurus
''Nectosaurus'' is a genus of thalattosaur (marine diapsid reptiles) which lived during the Late Triassic in what is now California. The type and only known species, ''Nectosaurus halius'', was found in the Hosselkus Limestone and described by John C. Merriam in 1905, making it one of the first thalattosaurians known (along with '' Thalattosaurus'').Sepkoski, J.J. (2002). "A compendium of fossil marine animal genera". ''Bulletins of American Paleontology'' 363: 1-560. Discovery ''Nectosaurus'' is known from fragmentary remains. The holotype, UCMP 9124, is an incomplete skeleton including vertebrae, a humerus, coracoid, ulna, radius, and partial skull and mandibles. Many isolated bones from other localities were referred to the genus by Merriam in 1908. In addition, a partial skull from the same locality, UCMP 9120, was referred to the genus as ''Nectosaurus sp.'' in 1905. This specimen is much larger than any specimen of ''Nectosaurus halius'' but is otherwise simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
