only the small anurognathid Vesperopterylus and small wukongopterid Kunpengopterus are known to possess prehensile feet and hands respectively; all other known pterosaurs have flat, plantigrade feet with no opposable toes, and the feet are generally proportionally small, at least in the case of the Pteranodontia.
