This book was released on 1953 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forty-five species of lower Middle Ordovician trilobites, including six new genera and thirty new species, are described and illustrated from the extensive collections in the United States National Museum. Most of these species occur in beds whose age and correlation have been a matter of controversy for more than a decade. The stratigraphic evidence afforded by the trilobites lends strong support to regional stratigraphic interpretations of the lower Champlainian beds in the Appalachian Valley, which have been worked out by G. Arthur Cooper and the writer fromdetailed study of brachiopod faunas and from physical stratigraphic studies. The trilobites, like brachiopods, are not so restricted in their facies distribution as are many groups of invertebrate fossils. Hence they are very useful in establishing contemporaneity of dissimilar facies. In this paper only the more common trilobites are described. The principal purpose of this study is to make available for biostratigraphic use a number of trilobite species, most of which have been confused or misidentified previously.

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 1989 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trilobites from the Upper Cambrian to Lower Ordovician Survey Peak, Outram and Skoki formations at Wilcox Pass, Alberta, comprehensively described in this report, belong to 48 genera. One new genus and six new species are described, and type material for seventeen previously described species from corresponding strata elsewhere in the Rockies is redescribed or re-illustrated. This report establishes a biostratigraphic framework for the Wilcox Pass sequence, from the highest part of the Upper Cambrian Trempealeau Series through the entire Lower Ordovician, based on trilobite zones.

This book was released on 2015-08-17 with total page 0 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.

This book was released on 2018-02-24 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Some Trilobites of the Lower Middle Ordovician of Eastern North America This paper is concerned primarily with the trilobites of the lower part of the Middle Ordovician of the Appalachian Province. It'is based upon collections made by the writer during expeditions to Pennsylvania, Virginia, and Tennessee, the cost of which was de frayed by the Shaler Memorial Fund at Harvard University. These trips were made in 1917, 1918, and 1921, and although primarily for the study of the stratigraphy of the Ordovician formations of the region, it soon became obvious that the perplexing problems presented could not be solved until the faunas were described.

Available in PDF, EPUB and Kindle. Book excerpt: "Trilobites are the most lifelike of fossils--many well-preserved specimens belie their great antiquity and seem almost ready to arch their bodies, peer about with their compound eyes, and crawl forward as if to complete a journey that was interrupted hundreds of millions of years ago."--from the Foreword"New York State is and has long been a magnet for trilobite hunters.... New York's trilobites were among the first illustrated fossils in North America.... Many outstanding localities in New York State, from the majestic Ordovician limestone bluffs of Trenton Falls, to the Silurian beds in the great gorge of Niagara River, to the Devonian shale cliffs of Lake Erie, continue to yield abundant and spectacular trilobite fossils. New York strata have also yielded more trilobites with preserved appendages and other "soft parts" than almost any other region of the world.... Spectacular, ornate trilobites from New York ranging from a few millimeters to nearly a half meter in length, are featured in museums all over the world."--from the PrefaceThis superbly illustrated book reviews the trilobite fossils found throughout New York State, including their biology, methods of taphonomy (preservation of specimens), and the broader Paleozoic geology of the state. A general chapter on the geology of New York State places the importance of these now-extinct invertebrate marine animals into context. Sixty-seven line drawings and 175 black-and-white photographs illustrate individual species, many represented here by type specimens, and display the eerie beauty that has made New York State trilobites favorites of collectors the world over.

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.
