Pozuelos salt flat, Quebrada El Paso (Eocene of Argentina)

Also known as Salar de Pastos Grandes

Where: Salta, Argentina (24.5° S, 66.6° W: paleocoordinates 26.6° S, 58.6° W)

• coordinate stated in text

• local area-level geographic resolution

When: Mustersan mammal zone, middle Member (Geste Formation), Priabonian (38.0 - 33.9 Ma)

• Powell et al., 2011: Recently, geologic and paleontologic evidence allowed the correlation of the upper levels of Lumbrera with Geste, Casa Grande, and Quebrada de los Colorados Formations. Additionally, these levels were referred to the late-middle Eocene (Casamayoran SALMA -South American Land Mammal Age-, Barrancan subage) by an U/Pb dating of 39.9 Ma . The lower levels of the Lumbrera Formation are here referred to the Vacan subage of the Casamayoran SALMA.

•DeCelles et al. 2007 obtained a Priabonian age for the fossiliferous levels of the Geste Formation. These levels were previosuly assigned a middle Eocene age based on faunal comparisons in Patagonia.

• member-level stratigraphic resolution
