Where: São Paulo, Brazil (22.3° S, 47.6° W: paleocoordinates 40.4° S, 17.4° W)
• coordinate estimated from map
• outcrop-level geographic resolution

• 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 'lower horizon' described in Mendes (1944).
• group of beds-level stratigraphic resolution
