A new basal non-pterodactyloid pterosaur,Changchengopterus pani gen.et sp.nov.,is erected,on the basis of a nearly complete postcranial skeleton.The new taxon is distinguished by relatively short extensions of the prezygapophyses,postzygapophyses and haemal arches of the caudal vertebrae;a humerus that has a subtriangular deltopectoral crest;limb elements that decrease in length in the following order:ulna>wing-phalange 2>wing-phalange 3=wing-phalange 1>humerus>tibia>femur>wing-metacarpal.Phylogenetic analysis suggests that Changchengopterus is a basal member of rhamphorhynchoids,and more closely related to Dorygnathus than to other rhamphorhychoids.The geological age of the Changchengopterus-bearing sediments is no latter than the end of the Late Jurassic and it is possible Middle Jurassic.
