Chuhsiungichthys

Chuhsiungichthys is an extinct genus of ichthyodectiform ray-finned fish that lived in freshwater environments in what is now Yunnan, China, and Kyushu, Japan during the Cretaceous. It differs from its sister genus, Mesoclupea, primarily by having a comparatively more anteriorly-placed dorsal fin.

It contains the following species:
 * †C. tsanglingensis Lew, 1974 - Turonian-Coniacian of Chuhsiung, Yunnan, China (Jiangdihe Formation)
 * †C. japonicus Yabumoto, 1994 - Albian of Kyushu, Japan (Kumagai Formation)
 * †C. yanagidai Yabumoto, 1994 - Hauterivian-Barremian of Kyushu, Japan (Dobaru Formation)
