Leptoptilos patagonicus is an extinct species of large bodied stork that existed during the late Miocene epoch. Discovered in the Puerto Madryn Formation in Chubut Province, Argentina, Leptoptilos patagonicus is the first fossil record discovery of a member of Leptoptilos in South America and the only one found so far in the New World.

Description

In comparison with extant Leptoptilos, Leptoptilos patagonicus is larger than Leptoptilos javanicus and similar in size to the largest members of Leptoptilos dubius and Leptoptilos crumeniferus. In comparison with extant Leptoptilos, the hindlimbs are larger than the forelimbs, resulting in shorter wings relative to extant Leptotilos, a characteristic shared by the extinct Leptoptilos falconeri. Leptoptilos patagonicus is smaller than Leptoptilos falconeri.

The humerus and ulna are shorter than those of Leptoptilos dubius and Leptoptilos crumeniferus. The tibiotarsus is shorter than that of Leptoptilos falconeri, but slighter longer than those usually found in Leptoptilos dubius and Leptoptilos crumeniferus.
