This book was released on 2021-07-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This 328-page hardback volume printed by the Illinois State Geological Survey includes over 1200 full-color, high-resolution photographs of fossil specimens collected from the Upper Ordovician Platteville Formation in the Upper Midwest USA. The described and illustrated fossil assemblage includes exceptionally well-preserved sponges, corals, bryozoans, brachiopods, polyplacophorans, gastropods, bivalves, rostroconchs, cephalopods, trilobites, ostracodes, echinoderms, graptolites, cornulitids, hyolithids, macroalgae, and a wide variety of trace fossils.This overview is directed to students, collectors, and professional paleontologists. Each chapter begins with a brief introduction to the morphological terms used to describe the various fossil groups, followed by systematic descriptions, remarks, and occurrence information. This overview can serve as a starting place and a source of inspiration for future paleontological research on the fossils of the Platteville Formation, offer insights regarding past climate and the environments in which life thrived, and ultimately shed light on the history of life on our planet.Many Platteville fossils were described in pre-20th century reconnaissance reports commissioned by the state geological surveys of Illinois, Iowa, Minnesota, and Wisconsin. A historical summary of paleontological investigations of the Upper Ordovician stratigraphic succession can be found in Sloan (1987). A drawback to understanding the documented faunal composition of the Platteville Formation is that many of the fossils are described and illustrated in diverse monographs and shorter papers spanning more than 150 years and published by a variety of organizations. Many of these publications are difficult to find in libraries and are not available online. Furthermore, they tend to focus on specific phyla rather than the overall faunal associations. An added drawback is that many early publications lack high-resolution photographs, making it difficult to compare and contrast fossil specimens.

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.
