Volgadraco, Cretaceous, 80 mya. Although it is incomplete, Averianov and colleagues assigned Volgadraco to the Azhdarchidae. Volgadraco is probably an intermediate between early, smaller azhdarchids and the giant azhdarchids that lived during the latest Cretaceous. Azhdarchids have been interpreted as terrestrial hunters, stalking small vertebrates including baby dinosaurs. The islands in which Volgadraco lived may have supplied prey, or they may have used them as nesting grounds.
