辽宁北票义县组翼龙化石具有个体中等大小、尾短、腹足发育、前肢强壮、桡骨和尺骨长于翼掌骨、跖骨极窄而细长、后肢退化而小的第五节趾骨等特征，应是一新属新种：Eosipterus yangi gen. et sp. nov.属于翼龙亚目的早期类群。这是辽宁省首次发现翼龙类化石。该化石为进一步确定热河动物群的性质和地质时代，以及研究古地理和古环境提供了新的证据。
The pterosaur from the Yixian Formation in Beipiao, Liaoning Province, is characterized by the medium–sized individual, short tail, presence of the gastralia, strong forelimbs, radius and ulna longer than wing–metacarpal, extremely narrow and elongate metatarsals, degenerated and small phalanx V of hindlimb and so on. It must be a new genus and species, Eosipterus yangi gen. et sp. nov., in the early groups of the Suborder Pterodactyloidea. This is the first record of pterosaurs found in Liaoning Province. The fossil provides new evidence for further determining the nature and geological time of the Jehol Fauna and for studying the palaeogeography and palaeoenvironment.
