A New Non‐Pterodactyloid Pterosaur from Qinglong County,Hebei Province of China

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.
