Beishanichthys is an extinct genus of freshwater ray-finned fish which existed in Gansu Province, China during the Olenekian age of the early Triassic period. It contains a single species, B. brevicaudalis, first named by Guang-Hui Xu, Ke-Qin Gao in 2011 based on fossils from the Lower Triassic lake deposits exposed in northern Gansu, China.[1][2] It is considered a scanilepiform, a group of early cladistians related to the modern bichirs, although Beishanichthys was not incorporated into the analyses that found this phylogenetic placement among the cladistians.[3]
