Chiayusaurus
Chiayusaurus (meaning "Chia-yu-kuan lizard", after where it was found) was a genus of sauropod dinosaur known from teeth found in Asia. Two species have been named for this obscure genus. It was originally named as Chiayüsaurus, but the ICZN does not permit special characters, so it has become Chiayusaurus. The old name can still be seen in older sources, though.
