Gruna das Três Cobras (Pleistocene to of Brazil)

Also known as Three Snakes Cave

Where: Bahia, Brazil (13.6° S, 43.8° W: paleocoordinates 13.6° S, 43.8° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Late/Upper Pleistocene to Late/Upper Pleistocene (0.1 - 0.0 Ma)

Environment/lithology: cave; lithology not reported

• Costa da Silva et al. 2019: Gruna das Três Cobras presents a horizontal projection of 5620 m ranging 32 m vertical according to the map by the Bambuí Group of Speleological Surveys (Sausse, 2013). The cave presents fossiliferous sedimentary deposits formed by fine to coarse and poorly sorted silty sand, periodically eroded by rain runoff (Fig. 2E).
• Costa da Silva et al. 2019: The Serra do Ramalho is sustained by sequences of Neoproterozoic pelitic and carbonate rocks belonging to the Paraopeba Subgroup of Bambuí Group, Jequitaí (not outcropping), Sete Lagoas, Serra de Santa Helena, Lagoa do Jacaré and Serra da Saudade formations (Auler and Farrant, 1996; Bitencourt and Rodet, 2002; Zalán and Silva, 2007), the last one restricted to high elevations in the northernmost part of the plateau (Conceição Filho et al., 2003). Cretaceous sandstones of Urucuia Formation overlay units of Bambuí Group, forming elevated sandy plains which stand out at the plateau summit (Conceição Filho et al., 2003, Fig. 2C).

Size class: macrofossils

Collection methods: Costa da Silva et al. 2019: Gruna das Três Cobras revealed a total of 281 samples. The material was stored in the paleontological collection of Museu de Ciências da Terra, Serviço Geológico do Brasil - CPRM (MCTer, Museum of Earth Sciences, Geological Survey of Brazil), in Rio de Janeiro, Brazil.
