An analysis of the nannofossil association structure, their abundance, and spatial distribution allowed us to perform a biogeographical zonation of the Paleogene in the Southern Ocean. The zonation schemes were compiled using the deep-sea drilling data (DSDP and ODP) for five time sections-Middle Paleocene, Eocene, Oligocene, and two schemes for the end of the Oligocene. By the end of the Paleocene, the unique climatic conditions of this period sharply changed and the mild tropical-subtropical environment of the Paleocene-Eocene became more contrasting and, in the Oligocene, bands of subpolar and temperate conditions appeared, which gradually expanded by the beginning of the Miocene.
