Where: La Pampa, Argentina (36.2° S, 65.1° W: paleocoordinates 36.4° S, 62.8° W)
• coordinate estimated from map
• small collection-level geographic resolution
When: Cerro Azul Formation, Huayquerian (8.0 - 5.0 Ma)
• Romano et al. 2023: Biochronological methods were useful in ordering and estimating the age of the different faunas of the Cerro Azul Formation, ranging from ca. 8 to ca. 5.7 Ma. Some appear to be transitional between Chasicoan and “Huayquerian” faunas (Cerro La Bota, Cerro Patagua, and Algarrobo del Águila), and other three (Barrancas Coloradas, El Guanaco, and Caleufú) cover the latest Miocene, even some of them could have reached the earliest Pliocene. The Cerro Azul Formation localities cover the range between ca. 8 to ca. 5.7 Ma (late Tortonian–Messinian; Late Miocene; Fig. 3; Supplementary Online Information 1, Tab. S8). 6.872 Ma (6.595 - 7.341 Ma) for Puesto Colorado.
