Eocene-Oligocene paleoceanography


Journal Article

Recent studies of Eocene-Oligocene paleoceanography based on the analysis of deep-sea microfossils are reviewed. Distinct changes in foraminiferal stable isotope compositions and biotic patterns occurred in the ocean near the Eocene/Oligocene boundary, but the data do not suggest a catastrophic extinction event took place at this time. The geological events can best be explained in terms of changing paleoceanographic and paleoclimatic conditions. The lack of a mass extinction of marine microfossils at the Eocene/Oligocene boundary argues against the existence of 26 m.y. cyclicity of extinctions in the Cenozoic. -from Authors
