- Abstract
A new Sordes-like pterosaur Jianchangopterus zhaoianus gen. et sp. nov. is erected based on a almost complete skeleton with skull preserved. It is characterized by the following characters: seven and six pairs of upper jaw and lower jaw teeth respectively; the development of a recess on maxilla; the evenness of the dental margin in lateral view; a distinct central ridge along dorsal surface of the mandibular symphysis; wing phalanx 4 with strongly curved shaft approximately 96% the length of the wing phalanx 1. The discovery of a Sordes-like pterosaur Jianchangopterus, and other taxa from the same formation indicates that pterosaurs reached great diversities during the Middle to Upper Jurassic period.
