This book was released on 1989-01-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 00 This study presents current data on vertebrate survival and extinction across the Cretaceous-Tertiary boundary in Montana. Nearly all the common taxa of reptiles (except dinosaurs), amphibians, and fish survived the end of the Cretaceous Period; extinctions were concentrated among rare groups and those found in near-shore habitats. The author concludes that ocean regression and climatic deterioration may explain these selective extinction patterns better than catastrophic hypotheses.

This book was released on 1996-01-01 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This volume atempts to explore and clarify the relationship among the geological records, the extinctions, and the causes of catastrophes for life in Earth's history. Most of the papers address the geological record and the extinctions across the Cretaceou-Teriary boundary, and the buried Chicxulub structure that is now consensually deemed to be of impact origin and to be intimately related to that boundary."

Download or read book T rex and the Crater of Doom written by Walter Alvarez and published by Princeton University Press. This book was released on 2013-06-25 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Download or read book Extinction and Radiation written by J. David Archibald and published by JHU Press. This book was released on 2011-03-15 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study identifies the fall of dinosaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. It refutes the single-cause impact theory for dinosaur extinction and demonstrates that multiple factors--massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact--likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial dinosaurs did not. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following nonavian dinosaur extinction. The author argues that because of dinosaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cenozoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cenozoic mammals evolved into the forms we recognize today in a mere ten million years after dinosaur extinction.

Book excerpt: This book provides concise and cutting-edge reviews in astrobiology, a young and still emerging multidisciplinary field of science that addresses the fundamental questions of how life originated and diversified on Earth, whether life exists beyond Earth, and what is the future for life on Earth. Readers will find coverage of the latest understanding of a wide range of fascinating topics, including, for example, solar system formation, the origins of life, the history of Earth as revealed by geology, the evolution of intelligence on Earth, the implications of genome data, insights from extremophile research, and the possible existence of life on other planets within and beyond the solar system. Each chapter contains a brief summary of the current status of the topic under discussion, sufficient references to enable more detailed study, and descriptions of recent findings and forthcoming missions or anticipated research. Written by leading experts in astronomy, planetary science, geoscience, chemistry, biology, and physics, this insightful and thought-provoking book will appeal to all students and scientists who are interested in life and space.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is dedicated to the interdisciplinary study of dynamic biological changes through the Phanerozoic which are associated with mass extinction events and similar biotic crises, and their causal mechanisms. In particular, it documents in detail the complex nature of terrestrial and extraterrestrial feedback loops that are associated with many mass extinction intervals. Authors have been asked to represent most of the known mass extinction events through time, and to comment on the complex earthbound or extraterrestrial causes (or both) for global biotic crises. The reader is offered new perspectives of extinction boundaries, a more innovative and diverse approach to causal mechanisms and mass extinction theory, blended views of paleobiologists, oceanographers, geochemists, volcanologists, and sedimentologists by an international cast of authors. No other book on extinction presents such a broad spectrum of data and theories on the subject of mass extinction.

Available in PDF, EPUB and Kindle. Book excerpt: Cretaceous-Tertiary Mass Extinctions: Biotic and Environmental Changes is a fascinating new study that combines the most current research on mass extinction with the theoretical perspectives of the leaders in the field. In twenty engaging essays, more than thirty leading paleobiologists and paleontologists uncover a wealth of data from the fossil record about changes in species survival and physical environments across the Cretaceous-Tertiary (K/T) boundary. Together these papers present a much-awaited global perspective on the bilogical and environmental changes taking place during this critical period in the history of life. Anyone interested in the K/T boundary controversy and how research scientists interpret the relationship between climate change and mass extinction will find this work essential.

This book was released on 1988 with total page 830 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of pollen and spores across the Cretaceous-Tertiary boundary in Garfield and McCone Counties, Montana was studied to determine whether the pattern of change in vegetation was compatible with a hypothesis of extraterrestrial impact as an agent of extinction. Fifteen sections in the (Cretaceous) Hell Creek and (Tertiary) Tullock Formations, including six boundary sections containing unusually high concentrations of iridium, were examined. Of 291 species of pollen and spores, 45 species of spores, 20 species of gymnosperms and about 225 species of angiosperms were recognized and described in Part II; these constitute the database upon which the statistical analysis in Part I rests
