       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.
