LATE CRETACEOUS OSTRACODS FROM THE CENTRAL AREA OF THE POTIGUAR BASIN, NORTHEASTERN BRAZIL

摘要

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.
