Kelliaichthys
Kelliaichthys is an extinct genus of prehistoric bony fish that lived during the Cisuralian epoch in what is now East Kazakhstan, Kazakhstan. It was originally named "Kellia" by Kazantseva-Selezneva. Because this genus name was already given to an extant lasaeid bivalve, the new name Kelliaichthys was erected for the Permian fish. The genus includes a single species : Kelliaichthys velox.
