Conodonts paleobiogeographic dynamic of the Pennsylvanian epicontinental sea Itaituba-Piauí, in the northern intracratonic Brazilian basins, Western Gondwana
During the Pennsylvanian, icehouse glacioeustasy and the debasement of Western Gondwana caused widespread transgressive-regressive cycles in the Itaituba-Piauí epicontinental sea located in modern-day South America. This seaway extended from the most distal and western Solimões basin, into the medial Amazonas basin, and at times into the most eastern and restricted Parnaíba basin. These basins contain a rich variety of marine (e.g., invertebrates, conodonts, foraminifers) and continental (plant pollen-spore assemblages) fossils. This paper presents the conodonts retrieved from outcrops and wells in the Carauari (Solimões Basin), Itaituba (Amazonas Basin), and the Piauí (Parnaíba Basin) formations. The conodonts recovered from these formations include Idiognathodus, Neognathodus, Adetognathus, Idiognathoides, Diplognathodus, Declinognathodus, and Hindeodus. Biostratigraphic correlation of this Pennsylvanian conodont assemblage is possible between the three studied basins. The conodont-bearing marine units can identify transgression episodes when the Itaituba-Piauí sea inundated these basins.
期刊介绍：
Marine Micropaleontology is an international journal publishing original, innovative and significant scientific papers in all fields related to marine microfossils, including ecology and paleoecology, biology and paleobiology, paleoceanography and paleoclimatology, environmental monitoring, taphonomy, evolution and molecular phylogeny. The journal strongly encourages the publication of articles in which marine microfossils and/or their chemical composition are used to solve fundamental geological, environmental and biological problems. However, it does not publish purely stratigraphic or taxonomic papers. In Marine Micropaleontology, a special section is dedicated to short papers on new methods and protocols using marine microfossils. We solicit special issues on hot topics in marine micropaleontology and review articles on timely subjects.
