Stable isotope record of soil carbonates from the Eocene-Oligocene transition, Badlands National Park, South Dakota, USA

Sections in and around Badlands National Park, Custer County, South Dakota contain a wealth of faunal and floral data within the White River Group. The Chadronian and Orellan North American Land Mammal Ages define the Eocene-Oligocene boundary here. Faunal and floral changes associated with the Chad...
