This book was released on 1999-03-25 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nearshore Marine Paleoclimatic Regions Increasing Zoogeographic Provinciality Molluscan Extinctions and Paleoshorelines California written by Clarence A. 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.

Download or read book Biostratigraphy and Vertebrate Paleontology of the San Timoteo Badlands Southern California written by L. Barry Albright III and published by Univ of California Press. This book was released on 2000-03-08 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Barendregt and published by Geological Society of America. This book was released on 2021-09-24 with total page 39 pages. Available in PDF, EPUB and Kindle. 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"--
