N2 - In ocean drilling sites, the taxonomy of Paleocene ostracodes has been poorly investigated. We describe and illustrate 18 ostracode taxa from Cretaceous-Paleocene sediments at U1407 of Integrated Ocean Drilling Program Expedition 342 off Newfoundland, Northwestern Atlantic; these 18 taxa belong to the families Cytherellidae, Bairdiidae, Pontocyprididae, Bythocytheridae, and Cytheruridae, and include five new species: Bythoceratina subumbonata sp. nov., Bythoceratina wilsoni sp. nov., Cytheropteron newfoundlandense sp. nov., Cytheropteron americanum sp. nov., and Nemoceratina (Pariceratina) guerneti sp. nov. Our identification and description of the taxa enable us to assess paleobiodiversity and paleoenvironments on the seafloor in the North Atlantic.
