Crato (Cretaceous of Brazil)

Where: CearĂ¡, Brazil (7.2° S, 39.4° W: paleocoordinates 8.7° S, 7.7° W)

• coordinate estimated from map

When: Santana Group, Late/Upper Aptian (122.5 - 112.0 Ma)

• From Melo et al. 2020: In summary, this integrated study of foraminifera, ostracodes and other microfossil data from the Romualdo Formation indicates that the local Alagoas Stage (Ostracoda Zone RT-011) can now be constrained to the Aptian. Arai and Assine 2020 also support that the Romualdo Formation is entirely Aptian in age.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

Size class: macrofossils
