Resumen:
In southern La Pampa Province the siliciclastic-limestone Vaca Mahuida Fm. deposits contain a diverse fauna that includes non-marine gastropods and bivalves, fishes, birds, anurans, and a primitive Notoungulata, which suggest an Eocene age. The depositional scenario is interpreted as a large, freshwater and probably oligotrophic lake subject to distinct bathynetric fluctuation. Occurrence of four depositional episodes is tentatively linked to climatic changes.
