The common presence of gonyaulacoid dinocysts including Apteodinium tectatum, Hystrichokolpoma rigaudiae, Tectatodinium pellitum, Pentadinium laticinctum, Reticulatosphaera actinocoronata, Dapsilidinium pseudocolligerum, Lingulodinium machaerophorum, as well as various Operculodinium, Spiniferites and Impagidinium species in Lower Serravallian and older deposits differs from the pollen-rich Upper Serravallian-Tortonian sediments in which protoperidinioid dinocysts such as Trinovantedinium, Lejeunecysta, Selenopemphix, and Brigantedinium spp. comprise a greater component of the cyst flora. This is consistent with global cooling associated with the growth of ice on Antarctica and the rapid progradation of terrigenous sediments across the New Jersey margin during the early Serravallian.completedStratigraphyAtlantic OceanCenozoiccontinental shelfDinoflagellataExpedition 313iceIntegrated Ocean Drilling Programlower Miocenemicrofossilsmiddle MioceneMiocenemiosporesNeogeneNew JerseyNorth Atlanticpaleoclimatologypalynomorphspollenpollen analysisprocessesSerravallianTertiaryUnited Statesurn:org.iodp:exp:313urnlargerWorkCitationcampaignEnglishgeoscientificInformation-80.000020.00000.000075.0000New JerseyNorth Atlantic
