- Abstract
- The described fragment of a pterosaur humerus (presumably from the Upper Jurassic deposits of the Volga Region) is one of the first finds of the Pterosauria in Russia. The humerus is characterized by a weak S-shaped curvature of the shaft, a distally tapering triangular deltopectoral crest, and a pneumatic foramen on the posterior side of the shaft. In terms of the shape of the deltopectoral ridge, this specimen is most similar to the humerus of the gallodactylid Cycnorhamphus suevicus (Quenstedt, 1855) from the Upper Jurassic of Western Europe. This feature, as well as the presence of a pneumatic foramen, allows us to attribute the studied form to Pterodactyloidea.
