Compared to pterosaurs from the Early Cretaceous from China, Late
Jurassic pterosaurs are relatively rare. A new rhamphorhynchid
pterosaur, Orientognathus chaoyngensis gen. et sp. nov., is erected
based on an incomplete skeleton from the Upper Jurassic Tuchengzi
Formation of Chaoyang, Liaoning Province, China. It is identified by
the following characters: the toothless tip of the lower jaw is
slightly pointed; the length ratio of wing metacarpal to humerus is
0.38, the ulna is shorter than each wing phalanx and the tibia is
nearly equal to femur in length. A phylogenetic analysis recovers
Orientognathus chaoyngensis as a rhamphorhynchid pterosaur.
Orientognathus chaoyngensis is perhaps the youngest Jurassic pterosaur
from western Liaoning Province of China.
