Changchengopterus pani - gen. et sp. nov.

Post autor: Ag.Ent »

Skoro wszyscy wrzucają coś z nowego Acta Geologica Sinica, to ja dorzucę pterozaura :)
LÜ Junchang (2009). A New Non-Pterodactyloid Pterosaur from Qinglong County, Hebei Province of China. Acta Geologica Sinica. 83 (2): 189-199.


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.
