(type), C. asianensis?

Chiayusaurus is a highly dubious genus of sauropod dinosaur because the type species is based upon the description of a tooth crown. The problem with such tooth taxons is that unless in exceptionally rare cases (like with Troodon), it is next to impossible to assign further remains. Even a second species named C. asianensis from South Korea is only represented by a tooth. In the past the teeth of Chiayusaurus have been noted to be similar to Asiatosaurus and Euhelopus.
