Ponte Velha I (Pleistocene of Brazil)

Also known as Touro Passo Creek; Uruguaiana

Where: Rio Grande do Sul, Brazil (29.7° S, 56.9° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Touro Passo Formation, Late/Upper Pleistocene (0.1 - 0.0 Ma)

• Bombin (1976) formally proposed the Touro Passo Formation for the upper Pleistocene fossiliferous deposits from western Rio Grande do Sul, based on the type section at the Milton Almeida locality, Touro Passo Creek. In the Touro Passo Creek, there are several fossiliferous deposits assigned to the upper Pleistocene, Lujanian Age (Equus neogaeus Biozone, sensu Cione & Tonni 2005) and the most important fossiliferous localities are the Ponte Velha I and II, Milton Almeida, Barranca Grande and Confluência do Pindaí (Kerber & oLiveira 2008a). Radiometric dating by thermoluminescence, AMS and 14C obtained ages between 43 and 11 ka BP (Bombin 1976; Milder 2000; Kotzian et al. 2005).

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; siltstone and claystone

• The fossil assemblages were deposited by a meandering river system in flood plains.
• Represented by silt and sand with carbonate concretions at the top, and point bars represented by basal conglomerates and sandstone, deposited on the Cretaceous basalts of Serra Geral Formation (Bombin 1976; Da-Rosa 2003; Oliveira & Kerber 2009).
