Book Synopsis Extinction by : Douglas H. Erwin

Download or read book Extinction written by Douglas H. Erwin. This book was released on 2015-03-22. Available in PDF, EPUB and Kindle. Book excerpt: Some 250 million years ago, the earth suffered the greatest biological crisis in its history. Around 95 percent of all living species died out—a global catastrophe far greater than the dinosaurs' demise 185 million years later. How this happened remains a mystery. But there are many competing theories. Some blame huge volcanic eruptions that covered an area as large as the continental United States; others argue for sudden changes in ocean levels and chemistry, including burps of methane gas; and still others cite the impact of an extraterrestrial object, similar to what caused the dinosaurs' extinction. Extinction is a paleontological mystery story. Here, the world's foremost authority on the subject provides a fascinating overview of the evidence for and against a whole host of hypotheses concerning this cataclysmic event that unfolded at the end of the Permian. After setting the scene, Erwin introduces the suite of possible perpetrators and the types of evidence paleontologists seek. He then unveils the actual evidence--moving from China, where much of the best evidence is found; to a look at extinction in the oceans; to the extraordinary fossil animals of the Karoo Desert of South Africa. Erwin reviews the evidence for each of the hypotheses before presenting his own view of what happened. Although full recovery took tens of millions of years, this most massive of mass extinctions was a powerful creative force, setting the stage for the development of the world as we know it today. In a new preface, Douglas Erwin assesses developments in the field since the book's initial publication.

Book Synopsis When Life Nearly Died: The Greatest Mass Extinction of All Time (Revised edition) by : Michael J. Benton

Download or read book When Life Nearly Died: The Greatest Mass Extinction of All Time (Revised edition) written by Michael J. Benton. This book was released on 2015-08-11. Available in PDF, EPUB and Kindle. Book excerpt: “The focus is the most severe mass extinction known in earth’s history. The science on which the book is based is up-to-date, thorough, and balanced. Highly recommended.” —Choice Today it is common knowledge that the dinosaurs were wiped out by a meteorite impact 65 million years ago that killed half of all species then living. It is far less widely understood that a much greater catastrophe took place at the end of the Permian period 251 million years ago: at least ninety percent of life on earth was destroyed. When Life Nearly Died documents not only what happened during this gigantic mass extinction but also the recent renewal of the idea of catastrophism: the theory that changes in the earth’s crust were brought about suddenly in the past by phenomena that cannot be observed today. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating, and Michael J. Benton gives his verdict at the end of the volume. The new edition brings the study of the greatest mass extinction of all time thoroughly up-to-date. In the twelve years since the book was originally published, hundreds of geologists and paleontologists have been investigating all aspects of how life could be driven to the brink of annihilation, and especially how life recovered afterwards, providing the foundations of modern ecosystems.
