Puntanipterus was a genus of ?dsungaripterid pterodactyloid pterosaur from the Upper Jurassic-Lower Cretaceous La Cruz Formation of San Luis, Argentina.
The genus was in 1975 named by José Bonaparte and Teresa Sánchez. The type species is Puntanipterus globosus. The genus name refers to the Puntanos, the colloquial name for the inhabitants of the province of San Luis after the old name of their capital "San Luis de la Punta de los Venados", and combines this with a Latinized Greek pteron, "wing". The specific name means "spherical" in Latin, a reference to the form of the lower tibia.
It is based on holotype PVL 3869 (earlier FML 3869) found in 1972, a 105 millimetres long tibiotarsus and seven centimetres long fibula; referred to it were a back vertebra and a wing and foot phalanx. The leg bones were described as similar to those of Pterodaustro (from slightly younger rocks), except for having an expanded spherical joint at the ankle and spiny processes on the side faces of the tibia at that end.
Bonaparte in 1978 classified Puntanipterus as a member of the Pterodaustridae. The same year Peter Wellnhofer was more careful and limited his assessment to a Pterodactyloidea incertae sedis. In 1980 Peter Galton concluded it belonged to the Dsungaripteridae. It was still by many considered to be a dsungaripterid by the time Peter Wellnhofer published The Illustrated Encyclopedia of Pterosaurs (several editions in the 1990s).
