“…Kennedy et al (2017) described a Hayesites albiensis/ irregularis association in the CC7 biozone, in the Vocontian Basin (France), since they had difficulty in distinguishing these two species in the studied sections. However, Bruno et al (2020) recorded both species individually in the Kwanza Basin (Angola), and Silva Jr. et al (2020) recorded Hayesites albiensis specimens in the CC8 biozone in the Sergipe-Alagoas Basin. The occurrence of Hayesites albiensis in the 5.55 m sample from the PE-01-SA section suggests the beginning of the Albian (CC8/NC8b biozone) (Araripe et al 2022).…”

The objectives of this study were the biostratigraphic and paleobiogeographic interpretations of the calcareous nannofossil records of the Romualdo Formation (Aptian-Albian) in the south-central portion of the Araripe Basin. The methods used to process the samples were decanting, smear slide, centrifugation, and ultra-thin section confection. The taxonomic and biostratigraphic interpretations were carried out through qualitative and quantitative investigations. A total of 11 genera and 17 species of calcareous nannofossils, namely,

“…During the late Aptian-Albian interval, the surface water connection between the South Atlantic and eastern Tethys (Central Atlantic segment) was fully formed, creating migration routes and physicochemical conditions in the water column that were ideal for the establishment of new marine biota (e.g., Dias-Brito, 1987;Riccardi, 1991;Feijó, 1996;Pérez-Díaz and Eagles, 2017). Fossil assemblages of the South Atlantic have shown a strong affinity to the Tethyan realm (e.g., Dias-Brito, 1987;Colin and Andreu, 1990;Koutsoukos, 1992;Arai, 2014;Silva et al, 2020;Bruno et al, 2020). However, South Atlantic ammonite fossils do not seem to show any affinity to the "Tethyan standard zonation" (Bengtson et al, 2018).…”

Abstract. The Aptian–Albian interval is characterized by significant paleoclimatic, paleoceanographic, and paleogeographic changes, which in turn affected the distribution and evolution of marine ecosystems. Despite the importance of such studies, there have been few correlations between Aptian–Albian sections of the Tethys Sea and those of the South Atlantic Ocean. This interval, including the Aptian–Albian transition, is preserved in the deposits of the Riachuelo Formation (Sergipe–Alagoas Basin, Brazil) located in the South Atlantic Ocean; therefore, this location was chosen for drilling four new cores. The goals of this paper are as follows: (1) to explain the drilling operation carried out in the deposits of the Riachuelo Formation and the methods used; (2) to present a brief lithostratigraphic characterization of the holes and the paleomagnetic data of core SER-03; and (3) to describe the high potential of the cores recovered for additional investigation in the future. The lithostratigraphic units of the SER-01 core consist mainly of coarse- to fine-grained sandstone, shales, marls, and mudstones; the SER-02 core was excluded due to low recovery; the SER-03 core is mainly composed of fine-grained sediments (shale, marls, and packstone) and bears some ammonite shells; the lithology of core SER-04 is mainly sandstones. Magnetic susceptibility values (χlf and χhf) and frequency-dependent susceptibility (χfd) data suggest that the section is located within the Cretaceous Normal Superchron. Future studies on these cores integrating micropaleontological, paleoichnological, geochemical, stratigraphic, and paleomagnetic (e.g., relative intensity) data will allow for a better understanding of paleoceanographic and paleogeographic events related to the early evolution of the South Atlantic Ocean and how these events correlate to similar events in Tethyan sections.
