Summary: Study of the antarctic Neogene suffers greatly from the lack of a diversity of biostratigraphic schemes compared with other parts of the world. Most microfossil groups are less diverse in the Antarctic than elsewhere, and a shallower CCD/lysocline reduces the usefulness of calcareous microfossils. While it is unlikely that a diversity of biostratigraphic schemes, comparable with that in more temperate climates, will ever evolve, there is scope for improvement on the current status. There is a need for examination of smaller microfossils and a search for fossilized remains of organisms that are not traditionally used elsewhere. Future sampling should be directed to recovering continuous sections with the specific aim of formulating new biostratigraphic schemes integrated with geochemical, geophysical and paleoenvironmental signals.
