Batiacasphaera edwardsiae sp. nov. was previously described under open nomenclature from the Miocene of the adjacent Rockall Plateau. Lejeunecysta challengerensis sp. nov. is recorded sporadically from the Burdigalian and Serravallian. Selenopemphix porcupensis sp. nov. and Trinovantedinium henrietii sp. nov. are large-sized dinoflagellate cysts with maximum dimensions of approximately 100 mu m. Selenopemphix porcupensis sp. nov. is recorded in the uppermost Burdigalian and Langhian, and Trinovantedinium henrietii sp. nov. is present in the Langhian and lowermost Serravallian. Batiacasphaera edwardsiae sp. nov. is possibly biostratigraphically significant for the Middle Miocene.completedStratigraphyPaleobotanyassemblagesAtlantic OceanBatiacasphaera edwardsiaebiostratigraphyCenozoicDinoflagellataExpedition 307geophysical methodsgeophysical profilesgeophysical surveysGonyaulacalesIntegrated Ocean Drilling ProgramIODP Site 1318Lejeunecysta challengerensismicrofossilsMiocenemorphologyNeogenenew taxaNorth AtlanticNortheast AtlanticpalynomorphsPeridinialesPeridiniphycidaePorcupine BasinPorcupine SeabightProtoperidinioideaeseismic methodsseismic stratigraphySelenopemphix porcupensissurveystaxonomyTertiaryTrinovantedinium henrietiiurn:org.iodp:exp:307urnlargerWorkCitationcampaignurn:org.iodp:exp:307:site:U1318urnlargerWorkCitationstudyurn:org.iodp:exp:307urnlargerWorkCitationcampaignEnglishgeoscientificInformation-11.3300-11.330051.260051.2600
