The late Aptian (Early Cretaceous) is a crucial time interval for understanding the paleoceanographic changes in Southern Hemisphere. Oceanographic emerging South Atlantic Ocean during this are reflected stratigraphic distribution of dinoflagellate communities recorded Muribeca and Riachuelo formations Sergipe Basin northeastern Brazil. Subtilisphaera community, lower middle parts section, appears to be related Ecozone suggests onset Tethyan influence central Atlantic, restricted...
Abstract The influence of the Intertropical Convergence Zone (ITCZ) in emerging South Atlantic region during late Aptian (Early Cretaceous) is reflected spatio-temporal distribution plant communities recorded eight Brazilian sedimentary basins. bioclimatic groups hygrophytes, hydrophytes, tropical lowland flora, upland and xerophytes was quantified using pollen spores. A predominance from xerophytic shrubland biome characterized pre-evaporitic, evaporitic, post-evaporitic paleoclimatic...
Abstract The break-up of Gondwana in the latest Jurassic and earliest Cretaceous subsequent opening evolution South Atlantic Ocean as a new widening seaway linking northern southern high latitudes, was single most significant palaeoceanographic event during with global consequences for climate biotic evolution, both on land at sea. Its main evolutionary stages are now becoming well known but, despite that, their impact has been widely underestimated. Aiming to shed light some these...
Large-scale biogeographic provinces of Cretaceous ammonoids, as currently defined in the literature, were delimited using qualitative assessments taxonomic inventories. Using aggregated species occurrences Paleobiology Database, we generated a geographic network to quantify connectivity Albian epicontinental basins and used flow-based Infomap algorithm delineate bioprovinces. Despite taxonomic, stratigraphic, limitations data, bioprovinces are largely concordant with traditional,...
Abstract Although an early Cambrian origin of cephalopods has been suggested by molecular studies, no unequivocal fossil evidence yet presented. Septate shells collected from shallow-marine limestone the lower (upper Terreneuvian, c. 522 Ma) Bonavista Formation southeastern Newfoundland, Canada, are here interpreted as straight, elongate conical cephalopod phragmocones. The material documented may push back in time about 30 Ma to unexpected stage biotic radiation metazoans, i.e. before first...
