A nearly complete skeleton with a lower jaw of pterosaur from the Early Cretaceous of western Liaoning is described and assigned to a new genus, Eoazhdarcho gen. nov.. The new genus is characterized by a relatively small size, the ratio of the length to width of the middle series cervical vertebrae approximately 3.5 and the ratio of humeral length to femoral length approximately 0.96. The humerus of Eoazhdarcho shows great resemblances to that of previously described Azhdarchidae, so it is assigned to the family Azhdarchidae.
