Book Synopsis Lower Ordovician trilobites of the Kirtonryggen Formation, Spitsbergen by : Richard A. Fortey
Download or read book Lower Ordovician trilobites of the Kirtonryggen Formation, Spitsbergen written by Richard A. Fortey and published by John Wiley & Sons. This book was released on 2013-10-22 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes early Ordovician (Ibexian: Tremadocian–early Floian) trilobites from Northern Spitsbergen from the section through the Kirtonryggen Formation adjacent to Hinlopen Strait. The Formation is divided into three Members, each with distinct trilobites collectively representing the fullest known succession from the Bathyurid biofacies of the eastern Laurentian carbonate platform. Previous research on the Ordovician of Spitsbergen is summarised and correlations with similar faunas previously described from Canada, Greenland, western Newfoundland, Vermont–New York State, Oklahoma and Missouri are discussed. Taxonomic problems are discussed in detail leading to the recognition of 53 species, of which 15 are new, belonging to 31 genera including four new. Twenty-four taxa are described under open or tentative nomenclature. The lower Member yields the earliest known occurrences of the Illaenoidea, Proetoidea and Scutelluoidea, supporting the hypotheses relating the origin of new major clades to inshore habitats.
Book Synopsis The Great Ordovician Biodiversification Event by : Barry D. Webby
Download or read book The Great Ordovician Biodiversification Event written by Barry D. Webby and published by Columbia University Press. This book was released on 2004-04-14 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. During the 46-million-year Ordovician Period (489–443 m.y.), a bewildering array of adaptive radiations of "Paleozoic- and Modern-type" biotas appeared in marine habitats, the first animals (arthropods) walked on land, and the first non-vascular bryophyte-like plants (based on their cryptospore record) colonized terrestrial areas with damp environments. This book represents a compilation by a large team of Ordovician specialists from around the world, who have enthusiastically cooperated to produce this first globally orientated, internationally sponsored IGCP (International Geological Correlation Program) project on Ordovician biotas. The major part is an assembly of genus- and species-level diversity data for the many Ordovician fossil groups. The book also presents an evaluation of how each group diversified through Ordovician time, with assessments of patterns of change and rates of origination and extinction. As such, it will become the standard work and data source for biotic studies on the Ordovician Period.

Book Synopsis Carbonate Mud-Mounds by : C. L. V. Monty
Download or read book Carbonate Mud-Mounds written by C. L. V. Monty and published by John Wiley & Sons. This book was released on 2009-04-13 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to investigate the structure, origin and evolution of carbonate mud-mounds. Mud-mounds are accumulations of biogenic carbonate sediment that are common in the geological record, and economically important as they host lead zinc mineralization and oil and gas. The book reviews, for the first time, the different mechanisms of mud-mound formation and examines in detail the major changes in mud-mound type and occurrence through geological time. The major part of the book contains case studies of mud-mounds from the Palaeozoic, Mesozoic and Cenozoic. The coverage is global and truly international, with 32 authors from 10 countries. The first volume to deal with the structure, formation and evolution of mud-mounds. Copiously illustrated, with nine colour plates.

Book Synopsis Global Events and Event Stratigraphy in the Phanerozoic by : Otto H. Walliser
Download or read book Global Events and Event Stratigraphy in the Phanerozoic written by Otto H. Walliser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: The existence of rapid and even catastrophic turnovers within the Phanerozoic ecosystems has been discussed controversially for more than 170 years. Since 1980 this discussion has become even more intensive after the hypothesis of Alvarez, explaining the end-Cretaceous mass extinction as the result of a huge asteroid impact on the Earth. This theory stimulated several thousand papers and is still controversial. The international research programme on "Global Biological Events in Earth History" attempts to bring the discussion back to the facts by using multidisciplinary investigations of the major Phanerozoic events. The results of an international group of experts are presented giving a wealth of information and a thorough discussion of the causes of the various global events.
