Jianghanichthys

Jianghanichthys is an extinct genus of basal cypriniform fish, and the only member of the family Jianghanichthyidae. It is also known as the "Chan Han fish" in the fossil trade.

Taxonomy
There are still disagreements as to the scientific classification, name and age of this species. However the body shape of Jianghanichthys differs from that of all Amyzon species. It was formerly placed in the genus Osteochilus before being reclassified into its own genus in 1987, and in 2015 it was moved from the Catostomidae to the new family Jianghanichthyidae.

Etymology
The genus name Jianghanichthys derives from "Jianghan", the place where fossil remains have been found, and "ichthys" derives from the Greek word for 'fish'.

Distribution
These fishes lived in the Early Eocene epoch. Fossils of Jianghanichthys have been found in Hubei, China.

These fossils are quite common and can be found in most shops.
