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
• basin-level geographic resolution
When: Romualdo Formation (Santana Group), Late/Upper Aptian (122.5 - 113.0 Ma)
• In recent stratigraphic schemes (e.g. Martill 2007) the Santana Formation and the "Romualdo Member" are essentially synonyms
•Santana Formation suggested to be early Albian in age by Heimhofer & Hochuli (2010) on the basis of palynomorphs
•Cerqueira et al. 2021:The Romualdo Formation was recently considered as Aptian in age, based on palynomorph, foraminifera and ostracod data (Arai and Assine 2020; Melo et al. 2020).
•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.
• member-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; concretionary, calcareous shale
•Cerqueira et al. 2021: characterized by conglomeratic sandstone followed by a sequence of green and black shale (Assine 2007), stratified conglomerates, fine-to medium-grained sandstone, laminated limestone, marl, and coquina levels (Assine et al. 2014; Melo et al. 2020). The black shale is occasionally intercalated with sev- eral layers where carbonate concretions are abundant (Fara et al. 2005; Saraiva et al. 2007; Vila Nova et al. 2011; Kellner et al. 2013).
