Where: Salta, Argentina (25.2° S, 66.5° W: paleocoordinates 27.5° S, 58.0° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Barrancan mammal zone, Quebrada de los Colorados Formation, Bartonian (41.3 - 38.0 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.
