This book was released on 2014-01-27 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Palaeozoic was a critical interval in the evolution of marine life on our planet. Through a window of some 120 million years, the Cambrian Explosion, Great Ordovician Biodiversification Event, End Ordovician Extinction and the subsequent Silurian Recovery established a steep trajectory of increasing marine biodiversity that started in the Late Proterozoic and continued into the Devonian. Biogeography is a key property of virtually all organisms; their distributional ranges, mapped out on a mosaic of changing palaeogeography, have played important roles in modulating the diversity and evolution of marine life. This Memoir first introduces the content, some of the concepts involved in describing and interpreting palaeobiogeography, and the changing Early Palaeozoic geography is illustrated through a series of time slices. The subsequent 26 chapters, compiled by some 130 authors from over 20 countries, describe and analyse distributional and in many cases diversity data for all the major biotic groups plotted on current palaeogeographic maps. Nearly a quarter of a century after the publication of the ‘Green Book’ (Geological Society, London, Memoir12, edited by McKerrow and Scotese), improved stratigraphic and taxonomic data together with more accurate, digitized palaeogeographic maps, have confirmed the central role of palaeobiogeography in understanding the evolution of Early Palaeozoic ecosystems and their biotas.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "The Ordovician period is a significant chapter in Earth's history that included the great Mid-Ordovician biodiversification event, the Hirnantian glaciation, and long-term greenhouse conditions. Ordovician rocks are widespread on most continents and the recent finalization of a modern chronostratigraphic classification of the Ordovician system now facilitates high-resolution correlations that allow for integrated multidisciplinary research. The diverse papers comprising this volume address orogenesis, paleogeography, climate modeling, sedimentation, biodiversity, and isotopic excursions; together they promote an integrated view of the Ordovician earth system."--Publisher's description.
