What is "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.

The type species, C. tsanglingensis, is found in Upper Cretaceous-aged strata of Chuhsiung, Yunnan Province. C. yanagidai is found in the first formation of the Lower Cretaceous-aged Wakino Subgroup, in Kyushu. C. japonicus is found in the fourth formation of the Wakino Subgroup.
