Where: Salta, Argentina (25.4° S, 65.9° W: paleocoordinates 25.6° S, 63.9° W)
• coordinate stated in text
• outcrop-level geographic resolution
When: Palo Pintado Formation, Late/Upper Miocene (11.6 - 5.3 Ma)
• The mammalian remains described here come from the lower section of the Palo Pintado Fm. (Fig. 1b). In the Tonco Valley, this unit has a partial thickness of 176m, the basal contact is transitional with the Angastaco Formation and the upper contact is an erosional unconformity with Quaternary sediments.
•Fossiliferous levels= level 0-4 (numbered from bottom to top).
•The age of fossil-bearing levels is approximately between 8 and 7 Ma (Payrola et al. in prep). cor- responding to the late Tortonian or the Messinian/Tortonian boundary (Cohen et al., 2013).
•deposited between 10.29 ± 0.11 Ma (K/Ar) to 5.27 ± 0.28 Ma (206 P b/238U; Coutand et al., 2006; Carrapa et al., 2006; Galli et al., 2008, 2014).
• group of beds-level stratigraphic resolution
Environment/lithology: "floodplain"; fine-grained sandstone and lenticular, medium-grained conglomerate
•
•Fossiliferous levels numbered 0, 1, 2, and 3 located within the fine-grained floodplain setting. All findings there were made on flooding plains, and each deposit has an average thickness of 4 m. Level 4 corresponds to a high lenticular conglomeritic channel deposit immediately above level 3 (Fig. 1b)
