The former exceed the latter throughout the Palaeocene and Eocene thus allowing diversity to build up to its acme in the middle Eocene where, in NP Zone 16 extinctions exceed originations for the first time. These events, the subsequent late Eocene/early Oligocene diversity crash followed by a recovery into the late Oligocene, and the diversity and evolutionary high low points of the Neogene and Quaternary, are discussed with reference to contemporary oceanic events and compared to circumstances in other oceans.completedInvertebrate paleontologyArthropodabiologic evolutionCenozoicCrustaceaDeep Sea Drilling Projectdeep-sea environmentDSDP Site 206DSDP Site 207DSDP Site 208DSDP Site 209DSDP Site 277DSDP Site 289IGCPInvertebrataLeg 21Leg 29Leg 30Mandibulatamarine environmentmicrofossilsOstracodaPacific OceanSouth PacificSouthwest Pacificspecies diversityWest Pacificurn:org.iodp:exp:21urnlargerWorkCitationcampaignurn:org.iodp:exp:29urnlargerWorkCitationcampaignurn:org.iodp:exp:30urnlargerWorkCitationcampaignurn:org.iodp:exp:21:site:206urnlargerWorkCitationstudyurn:org.iodp:exp:21urnlargerWorkCitationcampaignurn:org.iodp:exp:21:site:207urnlargerWorkCitationstudyurn:org.iodp:exp:21urnlargerWorkCitationcampaignurn:org.iodp:exp:21:site:208urnlargerWorkCitationstudyurn:org.iodp:exp:21urnlargerWorkCitationcampaignurn:org.iodp:exp:21:site:209urnlargerWorkCitationstudyurn:org.iodp:exp:21urnlargerWorkCitationcampaignurn:org.iodp:exp:29:site:277urnlargerWorkCitationstudyurn:org.iodp:exp:29urnlargerWorkCitationcampaignurn:org.iodp:exp:30:site:289urnlargerWorkCitationstudyurn:org.iodp:exp:30urnlargerWorkCitationcampaignEnglishgeoscientificInformation152.1116166.1129-52.1326-0.2955IGCP Project No. 246
