-Seventeen species of podocopid and platycopid Ostracoda were recorded in the 26 samples studied from the DSDP (= Deep Sea Drilling Project) Site 515B, Brazil Basin. The Trachyleberididae (eight spp.) and Krithidae (four spp.) are the most-represented families. Most species were left in open nomenclature because of scarcity or poor preservation. The assemblages composition shows moderate similarity to previously-studied deep-sea assemblages. The distribution pattern of the Eocene-Oligocene deep-sea ostracodes is briefl y discussed as a contribution to the understanding of Paleogene ostracode zoogeography.Key words: Ostracoda, Paleogene, paleoceanography, Brazil Basin, deep-sea.RESUMO -Dezessete espécies de ostracodes podocopídeos e platycopídeos foram registradas em 26 amostras estudadas do DSDP (= Deep Sea Drilling Project) Site 515B, Bacia do Brasil. As famílias Trachyleberididae (oito spp.) e Krithidae (quatro spp.) são as mais representativas. A maioria das espécies é registrada em nomenclatura aberta, seja pela escassez de espécimes ou por sua má preservação. A composição das assembleias mostra similaridade moderada quando comparada com outros estudos sobre ostracodes de águas profundas. A distribuição dos ostracodes do intervalo Eoceno-Oligoceno, em águas profundas, é brevemente discutida, visando uma contribuição ao conhecimento da zoogeografi a dos ostracodes paleógenos.Palavras-chave: Ostracoda, Paleógeno, paleoceanografi a, bacia do Brasil, águas profundas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
