Hall and published by Geological Society of America. This book was released on 2002 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3000 middle and late Cenozoic nearshore marine molluscan taxa from western California are assigned to six time periods, spanning ~25 m.y. In this interdisciplinary study, western California is palinspastically restored for each of the time periods by backsliding and back-rotating large fault blocks or crustal units. Marine fossil assemblages are assigned to nearshore paleoclimatic regions or water masses within palinspastically restored California. In addition, this volume reveals positive feedback mechanisms between paleolatitudinal changes in sea-surface paleotemperature gradients and changes in the diversity of marine mollusks along the California coast through time; defines "equable" based effective temperatures; and analyzes extinction rates among macroinvertebrate marine taxa from coastal California and the possible causes of these extinctions. The late Paleogene to Neogene faunas reflect an increase in faunal diversity related to strengthened temperature gradients, greater extremes in sea-surface temperatures, reduction in temperateness, and the development of an embayed California coastline.

Book excerpt: "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"--

This book was released on 2004-04-21 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book places into modern context the information by which North American mammalian paleontologists recognize, divide, calibrate, and discuss intervals of mammalian evolution known as North American Land Mammal Ages. It incorporates new information on the systematic biology of the fossil record and utilizes the many recent advances in geochronologic methods and their results. The book describes the increasingly highly resolved stratigraphy into which all available temporally significant data and applications are integrated. Extensive temporal coverage includes the Lancian part of the Late Cretaceous, and geographical coverage includes information from Mexico, an integral part of the North American fauna, past and present.
