Two bone fragments of ornithocheiroid pterosaurs from the Cenomanian of Volgograd region, Southern Russia
Two pterosaur bone fragments, a distal humerus and a distal femur, from the upper Cenomanian of the Volgograd Region in the Don River basin of southern Russia are reported. Although fragmentary, these bones come from mature individuals and are exceptionally well and three−dimensionally preserved, allowing a detailed description of their anatomy. Both specimens can be referred to a middle−sized ornithocheiroid pterosaur with a reconstructed wingspan of about 4 m. The humerus shows affinities with Istiodactylus from the Barremian of England, whereas the femur fragment is not identifiable beyond Ornithocheiroidea indet
