Abstract:In the latter part of the last century the peasants of Xinpu township, Guanling County, Guizhou Province, dug out many marine reptile and fish fossils during excavating the crinoid fossils within the Upper Triassic Wayao Member of the Falang Formation, which were sold as a kind of fantastic stone. The crinoid and marine reptile fossils have been studied and described by many palaeontologists, but the study of the fish fossils may be said to be very little and incorrect. From 2000 to 2004, very fortunately we collected some fish fossils from that member. According to our preliminary examination they represent 5 species and an indeterminated species of 5 genera falling into 5 families of 5 orders, among them 1 genus and 5 species are new, namely Guizhoucoelacanthus guanlingensis Liu, Yin et Wang S Y gen. et sp. nov. of the family Coelacanthiidae, Birgeria guizhouensis Liu, Yin et Luo sp. nov. and Birgeria sp. of the family Birgeriidae, Pholidopleurus xiaowaensis Liu et Yin sp. nov. of the family Pholidopleuridae, Peltopleurus brachycephalus Liu et Yin sp. nov. of the family Peltopleuridae, and Guizhoueugnathus largus Liu, Yin et Luo sp. nov. of the family Eugnathidae. This fish assemblage from the Wayao Member of the Falang Formation is very different from that of the Zhuganpo Member of the Falang Formatian of neighbouring district in nature. Because the Wayao Member overlies conformably the Early Carnian Zhuganpo Member which was dated depending on the conodonts, the age of the present fish assemblage is probably of the Middle Carnian. The new fishes from the Wayao Member are described briefly as follows.
Keywords:Fishes  Late Triassic  Carnian  Guanling  Guizhou
