Book Synopsis Paleobiology and Paleoenvironments of Eocene Rocks by : Jeffrey D. Stilwell

This book was released on 2000-01-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 76. Michael K. Brett-Surman, George Washington University, observed that, "being a paleontologist is like being a coroner except all the witnesses are dead and all the evidence has been left out in the rain for 65 million years." In the study of paleontology in Antarctica it could also be added that, if not left out in the rain, most of the evidence remains buried beneath several thousand feet of ice. Elucidating the geologic history of the Antarctic continent will always be plagued with this problem. Nonetheless, numerous clever means have been used to extract as much information as is possible, and as presented in this volume. In this light, one of the most intriguing time intervals in Antarctic history is the Eocene Epoch. During this time, the climatic conditions deteriorated rapidly from the so-called "Greenhouse" conditions that dominated Earth's conditions from mid-Mesozoic time through the early Cenozoic to the "Icehouse" conditions that have dominated the climate since that time. Unfortunately, the record of Eocene rocks on the continent is sparse. On the Antarctic Peninsula, specifically on Seymour Island, a robust record of Eocene rocks and fossils has provided virtually all the information we possess about this time interval. Thus the discovery and description of Eocene erratic boulders in morainal deposits in the McMurdo Sound region provides only the second site on the entire continent where we can study the paleontology of this time interval. In all likelihood, the description of erratics containing fossils from any other place in the world would warrant little study and would attract even less attention. However, when most of the vast area of Antarctica lies beneath ice and when clues to the nature of the crust of that part of the continent can be extracted only from study of erratics, the discovery carries with it some excitement.

Book Synopsis Frozen in Time by : Jeffrey D Stilwell
Download or read book Frozen in Time written by Jeffrey D Stilwell and published by CSIRO PUBLISHING. This book was released on 2011-10-12 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent’s great jigsaw of life.
Book Synopsis Paleontology of the Upper Eocene Florissant Formation, Colorado by : Herbert William Meyer
Download or read book Paleontology of the Upper Eocene Florissant Formation, Colorado written by Herbert William Meyer and published by Geological Society of America. This book was released on 2008 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Florissant formation's fossil beds and petrified forest are interesting in themselves but also shed light on questions of paleoecology, macroevolution, and taphonomy (the study of the process of fossilization). Meyer (National Park Service. Florissant Fossil Beds National Monument, Colorado) and Smith (U. of Colorado Museum of Natural History--Paleontology/geological sciences, UC, Boulder) introduce 11 papers examining Florissant fossil flora, fauna, mineralogy and geochemistry through different periods and via a model of the role of microbial mats in its preservation. An integrated database/Web site to further related research is also discussed. The monograph is well-illustrated with geologic maps and images of historical figures in the field and specimens, but is not indexed.

Book Synopsis Late Cretaceous/Paleogene West Antarctica Terrestrial Biota and its Intercontinental Affinities by : Marcelo Reguero
Download or read book Late Cretaceous/Paleogene West Antarctica Terrestrial Biota and its Intercontinental Affinities written by Marcelo Reguero and published by Springer Science & Business Media. This book was released on 2012-12-19 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most intriguing paleobiogeographical phenomena involving the origins and gradual sundering of Gondwana concerns the close similarities and, in most cases, inferred sister-group relationships of a number of terrestrial and freshwater vertebrate taxa, e.g., dinosaurs, flying birds, mammals, etc., recovered from uppermost Cretaceous/ Paleogene deposits of West Antarctica, South America, and NewZealand/Australia. For some twenty five extensive and productive investigations in the field of vertebrate paleontology has been carried out in latest Cretaceous and Paleogene deposits in the James Ross Basin, northeast of the Antarctic Peninsula (AP), West Antarctica, on the exposed sequences on James Ross, Vega, Seymour (=Marambio) and Snow Hill islands respectively. The available geological, geophysical and marine faunistic evidence indicates that the peninsular (AP) part of West Antarctica and the western part of the tip of South America (Magallanic Region, southern Chile) were positioned very close in the latest Cretaceous and early Paleogene favoring the “Overlapping” model of South America-Antarctic Peninsula paleogeographic reconstruction. Late Cretaceous deposits from Vega, James Ross, Seymour and Snow Hill islands have produced a discrete number of dinosaur taxa and a number of advanced birds together with four mosasaur and three plesiosaur taxa, and a few shark and teleostean taxa.
Book Synopsis The Transantarctic Mountains by : Gunter Faure
Download or read book The Transantarctic Mountains written by Gunter Faure and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.

Book Synopsis Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula by : John B. Anderson
Download or read book Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula written by John B. Anderson and published by John Wiley & Sons. This book was released on 2013-05-02 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Special Publications Series. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula presents the analysis of data collected during the SHALDRIL program, which sampled the most complete Cenozoic stratigraphic section in the Antarctic Peninsula. The stratigraphic intervals sampled fill major gaps in the existing stratigraphic record in the region, which is believed to have been the last place in Antarctica to become fully glaciated and, as such, the last refugium for plants and animals living on the continent. Providing previously unpublished results from studies aimed at improving our understanding of the changes in climate, glacial setting, and fauna and flora that took place over the past 30 million years, the volume highlights include discussions of marine seismic and drill core records documenting the initial growth and expansion of an ice sheet across the northernmost Antarctic Peninsula continental shelf in the northwestern Weddell Sea. The book features: Detailed vegetation and phytoplankton evolution from greenhouse through icehouse conditions in Antarctica's last refugium Sand grain texture and micromorphology indicating ice sheet control of weathering style Exhumational history around the Drake Passage margins from thermochronology and sediment provenance Comprehensive review of the opening of the ocean passageway between Antarctica and South America and the associated regional tectonics. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula will be of interest to geologists, climatologists, and glaciologists interested in climate and cryosphere evolution and those factors that regulate it.
