The fossils described here were collected from the Lower Triassic (Olenekian) at two Majiashan sections in Chaohu City, Anhui Province, East China. Nine species belonging to five genera are introduced, including a new genus, Chaohuichthys, and some undetermined or unnamed fish specimens are discussed. The fish assemblage from Majiashan covers most of the Lower Triassic marine bony fish taxa known from China.
