Chiayusaurus

Chiayusaurus (meaning "Chia-yu-kuan lizard", after where it was found) is a genus of sauropod dinosaur known from teeth found in China and possibly also South Korea. Two species have been named for this obscure genus, though only the type, C. lacustris, is still seen as valid. It was originally named as Chiayüsaurus, but the ICZN does not permit special characters, so the name was corrected to Chiayusaurus. The obsolete name can still be seen in older sources, though. As a sauropod, Chiayusaurus would have been a large, quadrupedal herbivore.

==History and taxonomy== Birger Bohlin based Chiayusaurus on a tooth crown in the IVPP. This tooth was found in the Barremian (Early Cretaceous) Xinminbao Group of Gansu, China. This spatulate tooth crown was long, and was not similar to the younger genus Asiatosaurus. As it was based on such sparse material, it has largely been ignored or considered to be indistinguishable from other, better-known sauropods. For example, Russell and Zheng found its tooth to be indistinguishable from those of Mamenchisaurus.
