"The 'Atlas of oligocene planktonic foraminifera' provides a comprehensive re-assessment of the taxonomy, evolutionary relationships, stratigraphic distributions, and paleoecology of planktonic foraminifera from the Oligocene Epoch. Our work is founded on new scanning electron micrographs of most of the type specimens and extensive illustration of material from around the world. We have also included important species of the late Eocene and early Miocene that either complete a lineage or are critical to our understanding of phylogenetic relationships. The higher taxonomy is based on the examination of wall textures, providing the primary divisions into spinose, nonspinose and microperforate groups. New microstructural observations on the tests of microperforate and medioperforate planktonic foraminifera from the Oligocene have allowed two types and two subtypes of wall texture to be distinguished and described for the first time. Detailed range and phylogenetic charts of all the taxa are presented, and existing geochemical data are synthesized, with the addition of some new stable isotope data. A total of 128 species, of which 14 are new; and 26 genera, of which 2 are new, are described. This atlas contains over 140 plates, and more than 2000 SEM images and will be invaluable for biostratigraphers, paleontologists, and paleoclimatologists, both in academia and industry, and of importance to all those interested in the fossil record and evolution of life and climate. Future areas for research on Oligocene planktonic foraminifera are also identified"--Page 4 of cover.

They can be dated by the presence of a few key planktonic foraminiferal taxa, which provide excellent biostratigraphic markers, and are sometimes the only forms that can be used to date carbonate successions (see Fig.
