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.

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.

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.

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

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.

This book was released on 1995-02-01 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditionsâ€"or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient lifeâ€"and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening othersâ€"including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative toolsâ€"and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.

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.
