Abstract:Chaohusaurus geishanensis, an Early Triassic ichthyopterygians found in China, shares similar forefin and skull structures and reveals the systematic relationship to Grippia in Europe. However，it was difficult for further contrast because specimens later discovered in China were highly specialized in forelimb or incomplete. Here two nearly complete and non—specialized forelimbs of Chaohusaurus are described,which were found in the Lower Triassic Jialingjiang Formation in Hubei，and supplemented related information of basal ichthyopterygians in China. Morphological comparison reveals that the general features of the Early Triassic Chaohusaurus in Hubei were close to Ch.geishanensis of the same genus，but distinctively different from Ch.chaoxianensis. Its features such as relatively large individual， intermedium squeezing and deformation and pisiform development shared some similarities with Grippia， Utatsusaurus， Parvinatator and other Early Triassic ichthyopterygians. According to analysis and deduction on this basis，there were possibly two directions for evolution of Early Triassic ichthyopterygians. After the end-Permian mass extinction (EPME)，ichthyopterygians origin and soon differentiate during Olenekian.Some large individuals without specialized forelimbs and with strong motor ability achieved exchange between different regions，but some small individuals with specialized forelimbs and weak motor ability became local (eastern?Tethys) independently evolving branch. However，the revelation of the phylogenetic relationship between them and the monophyly of Chaohusaurus need to be tested with future studies.
