Parallel SEM and LM studies reveal that Thalassiosira bukryi Barron should be transferred to Azpeitia and suggest that Actinocyclus barronii Radionova is likely to be a variety of A. radionovae BarroncompletedPaleobotanyalgaeAntinocyclusAzpeitia bukryiCenozoicdiatomsEquatorial Pacificfloral studiesLeg 199lower MiocenemicrofossilsMiocenemorphologyNeogenenew namesnew taxaOcean Drilling ProgramODP Site 1219Pacific OceanPlantaeSEM datataxonomyTertiaryThalassiosira bukryiurn:org.iodp:exp:199urnlargerWorkCitationcampaignurn:org.iodp:exp:199:site:1219urnlargerWorkCitationstudyurn:org.iodp:exp:199urnlargerWorkCitationcampaignEnglishgeoscientificInformation-142.0100-142.01007.48007.4800
