| Popis: | The Jandaira Formation samples collected in the central region of the Potiguar Basin show a diverse Late Cretaceous ostracod fauna. The genera Cytherella, Bairdoppilata, Triebelina, Paracypris, Fossocytheridea, Ovocytheridea, Perissocytheridea, Protocosta, Soudanella, and Leguminocythereis indicate a marginal marine environment during the Santonian–Campanian. The analyzed material demonstrates that ostracods are significant indicators of changes in the depositional environment and paleoecological markers in marginal marine environments. Key words: taxonomy, Upper Cretaceous, paleoecology, neritic assemblages. As amostras provenientes da Formacao Jandaira, coletadas na regiao central da Bacia Potiguar, evidenciam uma diversificada fauna de ostracodes do Neocretaceo. Os generos Cytherella, Bairdoppilata, Triebelina, Paracypris, Fossocytheridea, Ovocytheridea, Perissocytheridea, Protocosta, Soudanella e Leguminocythereis indicam um ambiente marinho marginal no intervalo Santoniano–Campaniano. O material analisado demonstra que os ostracodes sao indicadores significativos de modificacoes no ambiente deposicional e marcadores paleoecologicos em ambientes marinhos marginais. Palavras-chave: taxonomia, Cretaceo Superior, paleoecologia, assembleias neriticas. |
