Balneario Saldungaray (Saldungaray fm) (Neogene of Argentina)

Where: Buenos Aires, Argentina (38.7° S, 61.7° W: paleocoordinates 38.9° S, 59.4° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Saldungaray Formation, Huayquerian (8.0 - 5.0 Ma)

• The Cerro Azul formation was assigned exclusively to the Huayquerian (Late Miocene; e.g., Montalvo and Casadío, 1988 and literature therein; Albino and Montalvo, 2006), whereas the Saldungaray formation was considered Montehermosan or even younger (Pliocene; e.g., Furque, 1967, González, 1984, Marshall et al., 1983, Verzi and Deschamps, 1996). However, recent biochronological data suggest a Chasicoan-Huayquerian age for the Cerro Azul Formation (Late Miocene; Verzi, 1999, Verzi et al., 2003, Verzi et al., 2004b, Montalvo et al., 2005), and a Huayquerian age for the localities here studied of the Saldungaray Formation (Verzi et al., 2004b, Deschamps, 2005).
