This book was released on 2008 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: A monographic study that deals with a major marine faunal turnover during the Late Ordovician global greenhouse/icehouse episodes. It aims to document the diversity change of brachiopods (one of the major groups of marine life during the Ordovician Period) from pre-extinction to extinction times.

This book was released on 2001 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of their generally great abundance and high diversity, brachiopods from the Red River and Stony Mountain formations of southern Manitoba are important to understanding the pattern, process, and rate of evolution, radiation, and extinction of the North American epicontinental marine shelly benthos during the Late Ordovician. This report presents a detailed taxonomic treatment of these brachiopods, coupled with an assessment of their implications for biostratigraphy, palaeoecology, and palaeobiogeography at continental and global scales.
Download or read book The Palynology and Micropalaeontology of Boundaries written by Alwynne Bowyer Beaudoin and published by Geological Society of London. This book was released on 2004 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores geological boundaries in time and space using palynology and micropalaeontology. Boundaries produce distinct signatures in the micropalaeontological record. They can tell us much about the response of biotic systems to environmental change in both marine and terrestrial realms. Different microfossil groups and geological contexts require their own approaches, definitions and considerations of boundaries. The papers here cover the methodology of boundary identification from biostratigraphical, ecological and palaeoenvironmental perspectives.
Download or read book Conodonts from Ordovician Silurian Boundary Strata Whittaker Formation Mackenzie Mountains Northwest Territories written by Godfrey S. Nowlan and published by Geological Survey of Canada. This book was released on 1988 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The taxonomic work provides detailed descriptions and illustrations of almost fifty species belonging to twenty-three genera. One new genus and five new species are erected. The resulting taxonomic framework is used to provide a correlation with strata of this age in other sedimentary basins in Canada and elsewhere.

Available in PDF, EPUB and Kindle. Book excerpt: It has become apparent from the literature that bioerosional processes affect a wide range of biological and geological systems that cross many disciplines among the sciences. This book is dedicated to crossing those traditional disciplinary boundaries to present a united and current perspective on the pattern and process of bioerosion. The book opens with papers on the evolutionary significance of bioerosion. It concludes with a primer on the bioerosion bibliography website.

This book was released on 2023-06-08 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ordovician was one of the longest of the geological periods, characterized by major magmatic and tectonic activity, an immense biodiversification, swings in climate and sea levels, and the first Phanerozoic mass extinction. ‘A Global Synthesis of the Ordovician System’ is presented in two volumes in The Geological Society, Special Publications. Whereas the first volume (SP532) concentrates on general aspects and a synthesis of the Ordovician geology of Europe, this volume (SP533) includes reviews of Ordovician successions of most other parts of the world. The classic successions of the Ordovician basins of North America are presented, as well as those of China where several of the Ordovician Global Boundary Stratotype Sections and Points are defined. The volume also includes syntheses of the Ordovician geology of Africa, South America, most regions of Asia from the Near to the Far East along with Central Asia, as well as Australia, New Zealand and Antarctica.

This book was released on 1983 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The results of this study allow more precise correlations to be made with the classic Lower Silurian rocks of the Welsh Borderland in Great Britain, and will also facilitate making closer correlations between strata of this age in other sedimentary basins in Canada and elsewhere. Accurate dating of rocks is of great importance in assessing the hydrocarbon and other mineral potential of sedimentary basins." --

Download or read book Canadian Inland Seas written by I.P. Martini and published by Elsevier. This book was released on 2011-09-22 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: The various chapters of this book have been written by researchers who are still working in the Canadian Inland Seas region. The chapters synthesize what is known about these seas, yet much still is to be learnt. It is hoped that this collection of information will serve as a springboard for future, much needed, studies in this fascinating, diverse region, and will stimulate comparative analyses with other subarctic and arctic basins of the world. The Canadian Inland Seas are the only remnants, albeit cold, of the ancient cratonic marine basins which occupied central North America throughout the Paleozoic and part of the Mesozoic. Precambrian rocks and gently dipping Paleozoic sedimentary rocks underlie the seas. The area is also close to the centers of Pleistocene glaciations. The coastal areas represent an emerged landscape of the post-glacial Tyrrell sea, as the region has been isostatically uplifted to about 350 meters since glacial times. A total of 56 fish species inhabit Hudson Bay and James Bay. Seals, whales and one of the largest and southernmost populations of polar bears inhabit the seas as well. The coastal areas are important habitats for migratory bird populations, some of which migrate from as far away as Southern Argentina.The ostic environment has preserved these regions relatively unchanged by man, with only a major harbour at Churchill, Manitoba, which is active for part of the year, and a second large, rail-terminal settlement in the south at Moosonee, Ontario. A few, small, native Indian and Inuit villages dot the coasts. The seas are being affected indirectly by the damming of rivers for the generation of hydroelectric power, and by drainage diversions towards the man-made reservoirs. A major project is being completed in Quebec east of James Bay, but other rivers in Ontario and Manitoba have been dammed as well. Undoubtedly freshwater is one of the more important resources of the area, however its exploitation needs careful thought because of the possible long-range effects on the environment, particularly the coastal marshes, which sustain much of the eastern American intercontinental migratory avifauna. Other resources occur in the regions, primarily minerals and perhaps petroleum. For the most part however, such resources remain to be discovered.
