Abstract

The Jandaíra 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 Formação Jandaíra, coletadas na região central da Bacia Potiguar, evidenciam uma diversificada fauna de ostracodes do Neocretáceo. Os gêneros 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 são indicadores significativos de modificações no ambiente deposicional e marcadores paleoecológicos em ambientes marinhos marginais.

Palavras-chave: taxonomia, Cretáceo Superior, paleoecologia, assembleias neriticas.
