Resumen:
THE sabre-tooth cat Smilodon Lund, 1842 was a common elementof the Late Pleistocene faunas of America, with a widedistribution from northern North America through southernSouth America (Ultima Esperanza, Chile; Canto, 1991; Molet al., 2003; Prevosti and Vizcaíno, 2006; Labarca et al., 2008;Prieto et al., 2010). In South America it is represented in mostcountries (Venezuela, Ecuador, Brazil, Bolivia, Peru, Argentina,Uruguay, Chile; Berta, 1985; Kurtén and Werdelin,1990; Canto, 1991; Mol et al., 2003; Rincón, 2006; Labarcaet al., 2008; Prieto et al., 2010), Smilodon fatalis Leidy, 1868being limited to northwestern of South America (Peru,Ecuador), and Smilodon populator Lund 1842 to the rest ofthe continent (Kurtén and Werdelin, 1990). For a long time,the southern limit of Smilodon populator was the Pampean Region,but Canto (1991) described a premaxillary from southernPatagonia (Cueva Lago Sofía 4, Ultima Esperanza, Chile;Fig. 1). Later findings added new records from this area, includingnew localities (Cueva del Medio, Cueva del Milodón;Barnett et al., 2005; Mol et al., 2003; Labarca et al., 2008; Prietoet al., 2010). Barnett et al. (2005) and Prieto et al. (2010)gave some of the few taxon dates for this taxon, that have agesof 11,265 ± 45; 11,420 ± 50; and 11,100 ± 80 14C years BP.Other taxon dates came from Brazil: of 9260 ± 150; 14,580 ±90; and 10,790 ± 60 14C years BP (Hubbe et al., 2013), andArgentina: 13,400 ± 200 (Scanferla et al., 2013).
