Lapa Vermelha (Pleistocene to of Brazil)

Where: Minas Gerais, Brazil (19.6° S, 44.0° W: paleocoordinates 19.6° S, 43.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Pleistocene to Pleistocene (2.6 - 0.0 Ma)

• Gomes et al. 2019: The karst is composed by calcarenites of the Sete Lagoas Formation (Bambuí Group), which are covered, for the most part, by significant pedological formations (Berbert-Born, 2002). Numerical dating of fossil mammals from this region by Accelerator Mass Spectrometry (AMS) revealed ages that correspond to the late Pleistocene (∼19-11 ka BP) (Hubbe et al., 2013) and ∼365 to 14 ka by U-series dating (Auler et al., 2006). Some taxa with living representatives had ages corresponding to the Holocene (Hubbe et al., 2011).

Environment/lithology: cave; lithology not reported
