Piovesan, E. K.; Fauth, G.; Bergue, C. T. (2020). Late Cretaceous ostracods from the central area of the Potiguar Basin, Northeastern Brazil. Revista Brasileira de Paleontologia. 23(2): 81-89.
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.
