A New Rhamphorhynchid Pterosaur (Pterosauria) from the Middle Jurassic
Tiaojishan Formation of Western Liaoning, China.

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.
