Book Synopsis The Bug Creek Problem and the Cretaceous-Tertiary Transition at McGuire Creek, Montana by : Donald L. Lofgren
Download or read book The Bug Creek Problem and the Cretaceous-Tertiary Transition at McGuire Creek, Montana written by Donald L. Lofgren and published by Univ of California Press. This book was released on 1995-08-31 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bug Creek assemblages from Montana, transitional in composition between typical Cretaceous and Paleocene vertebrate faunas, are critical to K-T extinction debates because they have been used to support both gradual and catastrophic K-T extinction scenarios. Geological and palynological data from McGuire Creek indicate that Bug Creek assemblages are Paleocene and restricted to channel fills entrenched into older sediments, suggesting that the Cretaceous component of the assemblage was reworked. Thus, the author concludes, "Paleocene dinosaurs" are an illusion and the K-T survival rate of mammals is low because the presence of Cretaceous mammals in Bug Creek assemblages is also the result of reworking.
Book Synopsis The Cretaceous-Tertiary Event and Other Catastrophes in Earth History by : Graham Ryder

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."

Book Synopsis Extinction and Radiation by : J. David Archibald
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 Synopsis Hazards Due to Comets and Asteroids by : Tom Gehrels
Download or read book Hazards Due to Comets and Asteroids written by Tom Gehrels and published by University of Arizona Press. This book was released on 1994 with total page 1340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.
Download or read book History of Life written by Richard Cowen and published by Wiley-Blackwell. This book was released on 2000-04-14 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: History of Life is not just for students, but for everyone interested in the history of life on our planet. Paleontology, the study of ancient life, requires some knowledge of biology, ecology, chemistry, physics and mathematics. However, the average person can have access to it without deep scientific training. This book serves three audiences: it is an introduction to palaeontology; a general education course that introduces nonspecialists to science and scientific thought; and an introduction to the history of life for biologists who know a lot about the present and little about the past. The author's aim is ambitious: to take you to the edges of our knowledge in palaeontology; to show you how life has evolved on Earth,;and to explain how we have constructed the history of that evolution from the record of rocks and fossils.

Book Synopsis Effects of Past Global Change on Life by : National Research Council
Download or read book Effects of Past Global Change on Life written by National Research Council and published by National Academies Press. 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.

Book Synopsis Biological Processes Associated with Impact Events by : Charles Cockell
Download or read book Biological Processes Associated with Impact Events written by Charles Cockell and published by Springer Science & Business Media. This book was released on 2006-05-18 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes. The IMPACT programme has 15 member states and the activities of the programme range from workshops to short courses on topics such as impact stratigraphy, shock metamorphism, etc. The program has also awarded mobility grants and been involved in the development of teaching aids and numerous publications, including this one.

Book Synopsis The Great Dinosaur Extinction Controversy by : Charles Officer
Download or read book The Great Dinosaur Extinction Controversy written by Charles Officer and published by Addison Wesley Publishing Company. This book was released on 1996-06-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980 Nobel Laureate Luis Alvarez announced his theory of the dinosaurs final demise: a gigantic meteorite crashed into the earth and raised a cloud of dust that caused darkness for years, suppressing photosynthesis, which impeded plant growth, and eventually starved the dinosaurs. This idea exploded into common awareness with almost unprecedented speed, and was instantly embraced by the media and the public. Almost without question, it quickly became the hottest scientific "fact". Unfortunately for Alvarez, many in the scientific community did to support this theory, and in fact later research showed the impossibility of such an idea. The Great Dinosaur Extinction Controversy chronicles the fantastic story of how this hypothesis became so widespread, the way it became "common knowledge" - from the pages of Science to The New York Times to Parade Magazine, the controversy it caused, and the ample scientific research that proves the theory wrong. Officer and Page also present an attractive and carefully investigated alternative explanation for the mass extinctions that occurred at the end of the Cretaceous period. Through this account they show the ways that sound science should be performed and the findings transmitted.
