Tremembé shales (Oligocene to of Brazil)

Also known as Taubaté basin

Where: Sao Paulo, Brazil (22.8° S, 45.9° W: paleocoordinates 22.9° S, 40.4° W)

• coordinate stated in text

• local area-level geographic resolution

When: Tremembé Formation (Taubaté Group), Late/Upper Oligocene to Late/Upper Oligocene (28.4 - 16.0 Ma)

• The sedimentation of this phase is represented by the Taubaté Group including the Resende (basal), Tremembé (middle) and São Paulo (top) formations (Riccomini et al., 1987, 2004; Riccomini, 1989)

• formation-level stratigraphic resolution

Environment/lithology: lacustrine; shale

• The Tremembé Formation is a lacustrine sedimentary unit in the Taubaté basin dated as Late Oligocene to Early Miocene (~30-20 Myr) based on its fossil content (Lima et al., 1985; Lundberg et al., 1998; Soria & Alvarenga, 1989).

Size class: macrofossils
