Jianghanichthyidae
''Jianghanichthys'' is an extinct genus of freshwater Cypriniformes, cypriniform fish from the Thanetian, Late Paleocene to Ypresian, Early Eocene of central and southern China, and the only member of the family Jianghanichthyidae. It is the oldest cypriniform fish known from body fossils, and the most Basal (phylogenetics), basal known cypriniform. The genus name ''Jianghanichthys'' derives from "Jianghan Plain, Jianghan", the place where the first fossil remains of ''J. hubeiensis'' were found, and "ichthys" derives from the Greek word for 'fish'. It is also known as the "Chan Han fish" in the fossil trade.

Cypriniformes
Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid ( carps and their kin) fish, such as barbs, loaches, botias, and minnows (among others). Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families (with some authorities having listed as many as 23), over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently.Eschmeyer, W.N., Fong, J.D. (2015Species by family/subfamilyin the Catalog of Fishes, California Academy of Sciences (retrieved 2 July 2015) Cyprinids are most diverse in South and Southeast Asia and are entirely absent from Australia and South America.Nelson (2006) At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo. Their closest living relatives are the Characiformes ( characins, tetras a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
