Where: São Paulo, Brazil (22.4° S, 47.7° W: paleocoordinates 40.5° S, 17.5° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Corumbataí Formation (Passa Dois Group), Capitanian to Capitanian (264.3 - 254.2 Ma)

• Mendes (1944) describes these beds as Upper Triassic on the basis of the bivalve fauna.

•Corumbataí Formation is Capitanian - Wuchiapingian in age based on a combination of U/Pb zircon dating and relationship with other local formations (Rocha-Campos et al. 2019).

•These beds are from the 'upper horizon' described in Mendes (1944).

• group of beds-level stratigraphic resolution
