Late Quaternary deep-sea ostracode taxonomy of the eastern North Atlantic Ocean

Taxonomic revision and re-evaluation of the eastern North Atlantic deep-sea ostracodes are conducted based on late Quaternary sediments from Ocean Drilling Program (ODP) Hole 982A, Rockall Plateau, eastern North Atlantic. Twenty one genera and 51 species were examined and (re-)illustrated with high-resolution scanning electron microscopy images. Six new species are described: Polycope lunaris, Argilloecia labri, Bythoceratina nuda, Cytheropteron colesoabyssorum, Cytheropteron colesopunctatum, and Cytheropteron paramediotumidum. Excellent fossil ostracode preservation in this sediment core enabled us to provide a robust taxonomic baseline of the eastern North Atlantic deep-sea ostracodes for application to palaeoceanographical, palaeoecological, and biogeographical studies.
