基　　金：This study was a major science and technology project(Grant No:9501122)under the Ministry of Geology and Mineral Resources.

摘　　要：The pterosaur from the Yixian Formation in Beipiao, Liaoning Province, ischaracterized by the medium-sized individual, short tail, presence of the gastralia, strongforelimbs, radius and ulna longer than wing-metacarpal, extremely narrow and elongatemetatarsals, degenerated and small phalanx V of hindlimb and so on. It must be a new genusand species, Eosipterus yangi gen. et sp. nov., in the early groups of the SuborderPterodactyloidea. This is the first record of pterosaurs found in Liaoning Province. The fossilprovides new evidence for further determining the nature and geological time of the JeholFauna and for studying the palaeogeography and palaeoenvironment.The pterosaur from the Yixian Formation in Beipiao, Liaoning Province, ischaracterized by the medium-sized individual, short tail, presence of the gastralia, strongforelimbs, radius and ulna longer than wing-metacarpal, extremely narrow and elongatemetatarsals, degenerated and small phalanx V of hindlimb and so on.
