•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 the locality of Portezuelo Sumich Norte (46? 570

•33.0900S, 70? 400 200W; Fig. 1a, b), numerous fossil remains (including primates) come from opposite sides of a badland ridge that probably preserves a part of the base of the middle sequence that has filled a scour cur into the top of the lower sequence (Bown and Larriestra 1990 fig. 9a; T. Bown, Pers. Com). There is an absolute age of ca. 16.8 Ma from a tuff of the Santa Cruz Formation that lies uncon- formably over the top of the Pinturas sequence (Bown and Larriestra 1990; Perkins et al. 2012; Fleagle et al. 2012);
