Download or read book Fossil Crinoids written by Hans Hess and published by Cambridge University Press. This book was released on 2002 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crinoids have graced the oceans for more than 500 million years. Among the most attractive fossils, crinoids had a key role in the ecology of marine communities through much of the fossil record, and their remains are prominent rock forming constituents of many limestones. This is the first comprehensive volume to bring together their form and function, classification, evolutionary history, occurrence, preservation and ecology. The main part of the book is devoted to assemblages of intact fossil crinoids, which are described in their geological setting in twenty-three chapters ranging from the Ordovician to the Tertiary. The final chapter deals with living sea lilies and feather stars. The volume is exquisitely illustrated with abundant photographs and line drawings of crinoids from sites around the world. This authoritative account recreates a fascinating picture of fossil crinoids for paleontologists, geologists, evolutionary and marine biologists, ecologists and amateur fossil collectors.

This book was released on 2021-11-19 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Collector's Guide to Fort Payne Crinoids and Blastoids is the first comprehensive guide for identifying the fossils of echinoderms from hundreds of millions of years ago, when North America was covered by a warm, equatorial sea. Crinoids and blastoids, echinoderms (the same family of marine animals to include starfish, sea urchins, and sand dollars) from the Fort Payne Formation in Kentucky, are rarely seen at gem, mineral, and fossil shows, nor are they regularly displayed at major museums. By combining high-quality color photographs and an accompanying descriptive text, William W. Morgan provides the first comprehensive identification guide to these fascinating fossils. Collector's Guide to Fort Payne Crinoids and Blastoids features photographs, often offering more than one view, of the best-quality specimens curated in the Smithsonian and other prominent invertebrate fossil museums. Morgan includes photographs that are unlabeled so that readers can test themselves to see whether they can differentiate some of the more subtle features that may be necessary for accurate identification.

Ausich and published by Cambridge University Press. This book was released on 2021-02-11 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of life on earth is largely reconstructed from time-averaged accumulations of fossils. A glimpse at ecologic-time attributes and processes is relatively rare. However, the time-sensitive and predictability of echinoderm disarticulation makes them model organisms to determine post-mortem transportation and allows recognition of ecological-time data within paleocommunity accumulations. Unlike many other fossil groups, this has allowed research on many aspects of echinoderms and their paleocommunities, such as the distribution of soft tissues, assessment of the amount of fossil transportation prior to burial, determination of intraspecific variation, paleocommunity composition, estimation of relative abundance of taxa in paleocommunities, determination of attributes of niche differentiation, etc. Crinoids and echinoids have received the most amount of taphonomic research, and the patterns present in these two groups can be used to develop a more thorough understanding of all echinoderm clades.

Download or read book Collector s Guide to Crawfordsville Crinoids written by William W. Morgan and published by Schiffer Publishing. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mississippian Age crinoids from Crawfordsville, Indiana, are known worldwide for their completeness, abundance, comparatively large size, and extraordinary aesthetic appeal. With over 100 detailed photos and drawings and incisive text, this book describes the locality, focusing on its exceptional value from both scientific and lay perspectives. The geologic region is explored, along with the factors believed to have led to the unusual preservation of these crinoids. Detailed descriptions of the morphology, geological history, and classification of stemmed Paleozoic age crinoids follows. Diagrams and photos of real specimens aid in understanding crinoid terminology and identifying and classifying these crinoids to the genus and species level. This book is written for both the new and advanced collector. It is also valuable to the new student of invertebrate paleontology. It provides updated insight into the morphology, classification, and identification of crinoid fossils collected at the Crawfordsville localities.

This book was released on 2022-05-26 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fossil crinoids are exceptionally suited to deep-time studies of community paleoecology and niche partitioning. By merging ecomorphological trait and phylogenetic data, this Element summarizes niche occupation and community paleoecology of crinoids from the Bromide fauna of Oklahoma (Sandbian, Upper Ordovician). Patterns of community structure and niche evolution are evaluated over a ~5 million-year period through comparison with the Brechin Lagerstätte (Katian, Upper Ordovician). The authors establish filtration fan density, food size selectivity, and body size as major axes defining niche differentiation, and niche occupation is strongly controlled by phylogeny. Ecological strategies were relatively static over the study interval at high taxonomic scales, but niche differentiation and specialization increased in most subclades. Changes in disparity and species richness indicate the transition between the early-middle Paleozoic Crinoid Evolutionary Faunas was already underway by the Katian due to ecological drivers and was not triggered by the Late Ordovician mass extinction.
