More than 60 species were determined. Distribution of these species along the section allowed us to establish the availability of eight biostratigraphic subdivisions of schemes of E. Martini (NN) and D. Bukry (CN): NN2 (CN 1c)-NN18 (CN12a). In the middle of the Middle Miocene and in the end of the Late Cretaceous-beginning of the Pliocene, two periods of stratigraphical gaps were noted in the section. They have a local nature and are only partly determined in adjacent drilling sites at the Rio Grande Rise.completedStratigraphyalgaeAtlantic OceanbiostratigraphybiozonesCenozoiccoresDeep Sea Drilling Projectdepositional environmentDiscoasteridaeDSDP Site 516ForaminiferaInvertebrataIPODLeg 72microfossilsMiocenenannofossilsnannoplanktonNeogenepaleo-oceanographypaleomagnetismplanktonPlantaePlioceneProtistaRio Grande RiseSouth Atlanticstratigraphic gapsTertiaryurn:org.iodp:exp:72urnlargerWorkCitationcampaignurn:org.iodp:exp:72:site:516urnlargerWorkCitationstudyurn:org.iodp:exp:72urnlargerWorkCitationcampaignEnglishgeoscientificInformation-35.1707-35.1706-30.1636-30.1635
