Magnetic polarity stratigraphy has become one of the most important tools for correlation of fossiliferous terrestrial deposits. Since 1975, many of the suitable fossiliferous terrestrial vertebrate-bearing sequences in North America, Eurasia, South

Diversity and faunal turnover of North American land mammals are calibrated against the magnetic polarity time scale for million-year intervals for the latest Eocene through late Oligocene. A major, gradual Late Eocene decline in diversity, caused mo

New magnetostratigraphic studies have been conducted on Early Oligocene sections at Flagstaff Rim and Ledge Creek, Natrona County, Wyoming and the Dilts Ranch, Converse County, Wyoming. Thermal demagnetization has considerably improved the polarity i

Magnetostratigraphic studies of the Oligocene White River Group in Wyoming, Colorado, Nebraska, and the Dakotas yield a radiometrically dated polarity stratigraphy that provides mid-Tertiary calibration points for the magnetic polarity time scale. An
