Where: San Jose, Uruguay (34.7° S, 56.8° W: paleocoordinates 34.7° S, 55.7° W)

• coordinate stated in text

• small collection-level geographic resolution

When: San José Formation, Montehermosan to Montehermosan (5.0 - 0.4 Ma)

• Originally, it was assigned Pliocene age (Francis & Mones 1965; Mones 1967), mainly based on several remains of mammals. However, recent studies have suggested the existence of Pleistocene levels in the formation (Mones 1988; McDonald & Perea 2002). Giant bird remains from this unit, or attributed to it, have also been reported (Tambussi et al. 1999; Rinderknecht & Noriega 2002).
