Also known as Araripe Plateau

Where: Ceará, Brazil (7.2° S, 39.3° W: paleocoordinates 8.7° S, 7.6° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Romualdo Formation (Santana Group), Late/Upper Aptian (122.5 - 113.0 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.

• bed-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; mudstone and concretionary limestone

Size class: macrofossils

Preservation: concretion

Collected by Lima in 1991
