Claim: The thighbones of the Tethydraco, a genus of azhdarchid pterosaur, seemed to be pteranodontid, and the wide ulnae fit the exceptional distal width of the humerus.
Evidence: Tethydraco is a genus of azhdarchid pterosaur that lived during the Late Cretaceous period (Maastrichtian stage) of what is now the area of present Morocco, about 66 million years ago. The thighbones were, more tentatively, referred because they seemed to be pteranodontid. However, the wide ulnae fit the exceptional distal width of the humerus.
