A RALLIDAE (AVES, GRUIFORMES) FROM THE PLEISTOCENE LA ESPERANZA FORMATION OF OLAVARRÍA (ARGENTINA)
Abstract
A tarsometatarsus recovered from the lower Pleistocene levels of the La Esperanza Formation in Olavarría, Argentina, represents the first avian remains reported from this locality. Its morphology and size allow its assignment to Aramides cajaneus (Aves, Gruiformes), a species that still occurs in or near the area. Members of the genus Aramides are terrestrial birds closely associated with wetland environments, providing valuable paleoenvironmental insight into the conditions that prevailed in the region during the Pleistocene.
