The youngest record of Carcharopsis (Chondrichthyes) from the Pennsylvanian of Xinjiang Uyghur Autonomous Region, China
چکیده انگلیسی

A chondrichthyan tooth having a serrated edge, from the Late Pennsylvanian of Xinjiang Uyghur Autonomous Region, China, was identified as Edestus sp. [Cheng, Z., Lucas, S.G., Zidek, J., 1996. Neues Jahrbuch für Geologie und Paläontologie, Monatshefte 1996 (11), 701-707]. Because of the lack of bilateral symmetry, the tooth does not belong to Edestus or any other known edestoid. It is too incomplete for a definite identification, but its features are consistent with Carcharopsis, which also has serrated teeth, and not with any other described late Paleozoic chondrichthyan genus. If it is Carcharopsis, it is the latest occurrence of the genus, which was previously known only from the Mississippian and the Early Pennsylvanian.
