Where: Santa Cruz, Argentina (47.0° S, 70.7° W: paleocoordinates 47.8° S, 65.0° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Pinturan zone, Pinturas Formation, Burdigalian (20.4 - 16.0 Ma)
• Pertains to "Middle Sequence" = "Pinturan" of Kramarz & Bellosi 2005

•Brandoni et al 2016: The absolute ages of ca. 17.99 Ma near the base of the Pinturas Formation at Estancia el Carmen (47? 120 44.6400S, 70? 340 9700W), and ca. 16.8 Ma in the Santa Cruz For- mation that overlies the Pinturas Formation at Portezuelo Sumich Norte (see Perkins et al. 2012 and Fleagle et al. 2012) (Fig. 1b) indicate that the lower and middle sequences from the Pinturas Formation would be similar in age to those from the coastal localities of the Santa Cruz Formation (‘‘typical Santacrucian fauna’’) with ages of ca. 18–16 Ma (Bown and Fleagle 1993; Fleagle et al. 1995; Tejedor et al. 2006; Perkins et al. 2012), and younger than those from the lower Fossil Zone of the Colhue-Huapi Member of the Sarmiento Formation (‘‘Colhuehuapian fauna’’) (Kramarz et al. 2010) with ages of ca. 20.4–20.0 Ma (Re´ et al. 2010) or 21.11–18.62 Ma (Dunn et al. 2013) (Fig. 2).
•Brandoni et al 2016: in Loma de La Lluvia (47?10 47.0300S, 70? 4307.7200W; Fig. 1a, d), the fossils from the middle sequence that at this locality lies above a tephra level of ca.19.9 Ma, which is not a confident age, and the relationships of this level with others from Pinturas For- mation are still unclear (Perkins et al. 2012; Fleagle et al. 2012).
