Book excerpt: Excerpt from Upper Ordovician Ecology of the Central Appalachians State and regional geologic maps provided the stratigraphic base for the study. The surveys of Butts Cloos Rodgers Stose Gray (1960) and Calver (1963) were supplemented by a number of quadrangle reports dealing with north-central Virginia and southern Pennsylvania. Other central Appala chian literature was surveyed for reference to any previously known exposures of fos siliferous Upper Ordovician rocks. Many of these previously published stratigraphic sections were adequate only in so far as they gave some indication of the overall thick ness of the fossiliferous upper Reedsville strata. The total number of localities visited amounted to more than 200, but fossils were present and collected from only 164. About specimens from these 164 fossiliferous exposures provided the basis for the description of 31 species (and/or genera) that are incorporated into a systematics section at the end of this paper. At over 90 localities fossils were collected from well defined stratigraphic horizons, approximately 35 additional localities served, to some degree, as accurate stratigraphic control; the remaining 40 localities were of more limited value, for the exact order and thickness of the various rock units were not clear at these exposures. In this study data were gathered concerning bedding fea tures, lithologic type and relative abundance of species. Tentative field identifications of both rock and fossil materials were checked in the laboratory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

This book was released on 2020-09-11 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Dr. John M. Dennison spent his career studying the Appalachians, teaching and mentoring his students and professional colleagues, publishing papers, leading field trips, and presenting ideas at regional, national and international conferences. This volume is a collection of papers contributed by former students and colleagues to honor his memory. Learn about stratigraphy and paleontology ranging in age from Ordovician to Mississippian in Kentucky, New York, Tennessee, Virginia, and West Virginia; Devonian airfall tephras throughout the eastern United States; a Devonian lonestone; a Middle Eocene bentonite in North Carolina and its relationship to a volcanic swarm in western Virginia; and a 3D model of a ductile duplex in northwestern Georgia. The stratigraphic and geologic diversity of the papers reflect Dennison's many interests and relationships with a large group of geoscientists"--

Available in PDF, EPUB and Kindle. Book excerpt: How will patterns of human interaction with the earth's eco-system impact on biodiversity loss over the long term--not in the next ten or even fifty years, but on the vast temporal scale be dealt with by earth scientists? This volume brings together data from population biology, community ecology, comparative biology, and paleontology to answer this question.
