Book Description
"Meighen Island is a keystone site in the Neogene Canadian High Arctic, unique in the Beaufort Formation for its interbedded marine tongue. This volume is a comprehensive report on the biostratigraphy, age, and correlation of Meighen Island to other important Arctic localities from the standpoint of deposits exposed in the area of Bjaere Bay on the west side of the Island. The authors consider the diverse fossil macrofloras and pollen, the terrestrial and marine faunas, magnetostratigraphy, and amino acid racemization and put this site in the context of major changes in climate and geography during the Pliocene"--

Book Description
Microtine history indicates mosaic evolution and complex dispersal patterns around the Northern Hemisphere ; by reflecting this history and evaluating stage of population evolution, microtine biochronology can discriminate time periods as brief as 5,000 years.

Book Description
The author describes forty-two fossil taxa recovered during a study of the San Timoteo Badlands that used magnetobiostratigraphy to develop a temporal framework for addressing the tectonic evolution of southern California over the last 6 million years. For the Pliocene, small mammals are an effective means of correlating a magnetostratigraphy to the Geomagnetic Polarity Time Scale when radioisotopic dates are unobtainable.

Book Description
This book is a unique and integrated account of the history of North American vegetation and paleoenvironments over the past 70 million years. It includes discussions of the modern plant communities, causal factors for environmental change, biotic response, and methodologies. The history reveals a North American vegetation that is vast, immensely complex, and dynamic.
