Data for: A Quantitative Analysis of Calcareous Nannofossils across a Late Oligocene Paleolatitudinal Transect of the North Atlantic Ocean

Dataset includes a complete range chart with all nannofossil species identified over six DSDP/ODP sites in the North Atlantic Ocean. The range chart provides qualitative data of nannofossil species abundances, sample numbers, depths, and preservation. Supplementary information includes tables and figures that could not be published with the manuscript.
