In general, the successions comprise abyssal biogenic sediments with nannofossil- and radiolarian-ooze end members. Stratigraphic highlights include recovery of richly nannofossiliferous Oligocene successions and complete Eocene/Oligocene and Oligocene/Miocene boundaries at four sites: U1331 through U1334 and U1332 through U1336, respectively. Here, we present a taxonomic overview of the Paleogene nannofossil assemblages from Sites U1331-1334, illustrating 163 taxa and including the description of 11 new species (Reticulofenestra moorei, Reticulofenestra westerholdii, Coccolithus scheri, Cruciplacolithus? klausii, Calcidiscus? edgariae, Calcidiscus? ka-mikurii, Helicosphaera robinsoniae, Pedinocyclus gibbsiae, Discoaster williamsii, Sphenolithus kempii, Sphenolithus richteri, Sphenolithus peartiae) and two new combinations (Calcidiscus? detectus, Coccolithus biparteoperculatus).completedStratigraphyPaleobotanyalgaeassemblagesbiostratigraphyCalcidiscusCenozoicCoccolithophoraceaeCoccolithusCruciplacolithus klausiiDiscoaster williamsiiEast PacificEoceneEquatorial PacificExpedition 320Expeditions 320/321floral listHelicosphaera robinsoniaeIntegrated Ocean Drilling ProgramIODP Site U1331IODP Site U1332IODP Site U1333IODP Site U1334lithostratigraphymicrofossilsMiocenemorphologynannofossilsNeogenenew namesnew taxaNorth PacificNortheast PacificOligocenePacific OceanPaleogenePlantaepreservationReticulofenestraSphenolithusstratigraphic boundarytaxonomyTertiaryurn:org.iodp:exp:320urnlargerWorkCitationcampaignurn:org.iodp:exp:320:site:U1331urnlargerWorkCitationstudyurn:org.iodp:exp:320urnlargerWorkCitationcampaignurn:org.iodp:exp:320:site:U1332urnlargerWorkCitationstudyurn:org.iodp:exp:320urnlargerWorkCitationcampaignurn:org.iodp:exp:320:site:U1333urnlargerWorkCitationstudyurn:org.iodp:exp:320urnlargerWorkCitationcampaignurn:org.iodp:exp:320:site:U1334urnlargerWorkCitationstudyurn:org.iodp:exp:320urnlargerWorkCitationcampaignEnglishgeoscientificInformation-142.0942-131.58248.000012.0405
