Eustatic variations during the Paleocene-Eocene greenhouse world:
We reconstruct eustatic variations during the latest Paleocene and earliest Eocene (∼58-52 Ma). Dinoflagellate cysts, grain size fractions, and organic biomarkers in marine sections at four sites from three continents indicate an increased distance to the coast during the Paleocene-Eocene thermal ma...
