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 183 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.

Download or read book The Evolution and Fossil Record of Parasitism written by Kenneth De Baets and published by Springer Nature. This book was released on 2022-01-01 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity. Volume two focuses on the importance of direct host associations and host responses such as pathologies in the geological record to constrain the role of antagonistic interactions in driving the diversification and extinction of parasite-host relationships and disease. To better understand the impact on host populations, emphasis is given to arthropods, colonial metazoans, echinoderms, mollusks and vertebrates as hosts. In addition, novel techniques used to constrain interactions in deep time are discussed ranging from chemical and microscopic investigations of host remains, such as blood and coprolites, to the statistical inference of lateral transfer of transposons and host-parasite coevolutionary dynamics using molecular divergence time estimation.

Download or read book Niche Evolution and Phylogenetic Community Paleoecology of Late Ordovician Crinoids written by Selina R. Cole and published by Cambridge University Press. 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.
