Where: Ceará, Brazil (7.2° S, 39.7° W: paleocoordinates 8.6° S, 8.1° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Romualdo Formation (Santana Group), Late/Upper Aptian (122.5 - 113.0 Ma)
• Santana Formation suggested to be early Albian in age by Heimhofer & Hochuli (2010) on the basis of palynomorphs
•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 and Santana Group is entirely Aptian in age.
