Where: Argentina (38.3° S, 57.9° W: paleocoordinates 38.3° S, 57.9° W)

When: Lujanian (0.8 - 0.0 Ma)

• ). The fossil was located in situ within a cave section (1.2 m diameter) which is 56 attributed to a Mylodontidae. The cave section is situated near the top of a 5 m sea cliff in which six 57 stratigraphic units can be recognized (Fig. 2). The lower deposits, units A–C, which are topped by 58 calcrete levels (C 1–3), correlated to units A–D of Tonni & Fidalgo (1982), units I–III of Alberdi et 59 al. (2006), and units A–E of Soibelzon et al. (2010). The faunistic content of these units 60 corresponds to Ensenadan Age/stage. The top units D–E, and the calcrete level atop (C 4) are 61 considered as Lujanian sensu lato, and could correlate to units E and F of Tonni & Fidalgo (1982). 62 Unit F is where the cave develops, this unit is transgressive to units D–E, and the surface form 63 where MPH-P 302 was recovered is at the level of unit E, close to C4. Unite F is assigned to the 64 Lujanian sensu stricto Stage/Age given that it correlates to unit G of Tonni & Fidalgo (1982) and 65 unit IV of Alberdi et al. (2006), which correspond to the Equus (Amerhippus) neogeus biozone 66 (Cione & Tonni, 2005). This is consistent with Glyptodon reticulatus shield fragments (MPH-P 034) 67 recovered in the superior part of unit F, above the cave.
