Uruguaiana (Pleistocene of Brazil)

Also known as Touro Passo creek

Where: Rio Grande do Sul, Brazil (29.7° S, 56.8° W: paleocoordinates 29.7° S, 56.8° W)

• coordinate stated in text

• local area-level geographic resolution

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

• The fossils were collected probably from the point that Bombim (1976) called “place with larger number of mammals”, in the carbonate level (medium portion of the “Mudstone Member”).

• group of beds-level stratigraphic resolution

Environment/lithology: "floodplain"; muddy sandstone and carbonate

• Bombim (1976) defined the Touro Passo Formation as being fluvial deposits of the flood plain of a homonym stream, presenting a conglomeratic facies (Conglomeratic Member), deposited during a flood, and covered by a muddy sandstone facies (Mudstone Member) with levels of CaCO3, developed in the consequent flood plain.

Size class: macrofossils

Collection methods: Repository: MCN-PV, paleovertebrate collection, Museu de Ciências Naturais of the Fundação Zoobotânica do Rio Grande do Sul, Porto Alegre (Brazil).
