Abstract

This work presents the stratigraphic distribution of several species of calcareous nannofossil in themiddle Eocene early - Oligocene from four Ocean Drilling Program (ODP) sites located between60° and 65°S paleolatitude in the Southern Atlantic and Indian Oceans. Useful nannofossil datumsthat should facilitate construction of age-models and contribute to an integrated chronology for theupper Paleogene Southern Ocean sediments from ~ 42 to 33 Ma are summarized. The distributionpatterns of calcareous nannofossils, studied by means of quantitative and semiquantitative methods,provide an improvement of the classical Southern Ocean biozonations, introducing newbiostratigraphically useful biohorizons, and testing their reproducibility within and outside theregion.
