First Finding of a Pterosaur in the Upper Cretaceous of the Southern Urals

A distal fragment of the wing metacarpal of a pterosaur from the Upper Cretaceous (Campanian) deposits of the Orenburg Oblast has been identified as Azhdarchidae indet . based on the following combination of characters: absence of a large pneumatic foramen on the posterior side proximal to the ventral condyle; an asymmetrical groove between the condyles, a ridge on the ventral side of the ventral condyle, and a significant posterior bend of the distal epiphysis and adjacent part of the diaphysis. This is the first pterosaur recorded from the Late Cretaceous of the Southern Urals.
