A new primitive ichthyopterygian Xinminosaurus catactes gen.et.sp.nov,is erected based on a complete skeleton from the Middle Triassic Upper Member of the Guanling Formation at Panxian,Guizhou,southwestern China.It has a suite of uniquely derived characters in its dentition,ulna,carpals and tarsals.It is similar to primitive ichthyopterygians in retaining elongated limb bones.The new taxon and a diversity of marine reptiles in Panxian Fauna are the physical markers of the Middle Triassic Biotic radiation.Detailed studies of this fauna will supply essential knowledge on the diversity,migration and paleobiogeographic affinity of Middle Triassic ichthyopterygians.
