Sanga Borba Creek (Pleistocene of Brazil)

Where: Rio Grande do Sul, Brazil (30.2° S, 52.1° W: paleocoordinates 30.1° S, 52.1° W)

• coordinate stated in text

• local area-level geographic resolution

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

• At the moment, there is no absolute dating for these deposits, but the presence of Equus (Amerhippus) neogaeus fossils suggest a Lujanian age (Ribeiro & Scherer, in press. In Scherer et al. 2009)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; white mudstone and muddy conglomerate

• This lithology represents an alluvial deposition, characterized by a fluvial facies at the base of the deposition, and slip processes on top.
• White mudstones partially exposed, eroded, and overlapped by a conglomerate with a muddy matrix, which constitute the floor of the drainage and contain the disarticulated and fragmented fossil material, suggesting reworking.

Size class: macrofossils

Collection methods: Repository: Laboratório de Estratigrafia e Paleobiologia, Universidade Federal de Santa Maria (Brazil)
