Age range of interval:28.90000 - 20.90000 m.y. ago
Stratigraphy
Geological group:Malargüe Formation:Agua de la Piedra
Stratigraphic resolution:bed
Stratigraphy comments: Base of the Agua de la Piedra Formation
Schmidt et al. 2019: The faunal assemblage was then assigned to the Late Oligocene (Deseadan SALMA) based on the presence of two typical representatives of the Deseadean fauna of Patagonia: Pyrotherium Ameghino, 1888 and Proborhyaena gigantea Ameghino, 1897 (Gorroño et al., 1979; Bond and Pascual, 1983; Cerdeño and Vera, 2017). New faunal data confirm the Deseadan age, but absolute dating is lacking for Quebrada Fiera.
