| Stratigraphy comments: 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. | |||||
