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"--

Biostratigraphy and Vertebrate Paleontology of the San Timoteo Badlands, Southern California
Author: L. Barry Albright III
Publisher: Univ of California Press
ISBN: 9780520915985
Category : Science
Languages : en
Pages : 160
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.
