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.
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.

Download or read book Collector s Guide to Fort Payne Crinoids and Blastoids written by William W. Morgan and published by Indiana University Press. 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 Great Ordovician Biodiversification Event written by B. D. Webby and published by Columbia University Press. This book was released on 2004 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. This is the first book devoted specifically to establishing the global patterns of differentiation of Ordovician biotas through time and space. It provides extensive genus- and species-level diversity data for the many Ordovician fossil groups and presents an evaluation of how each group diversified, with assessments of patterns of change, and rates of origination and extinction.
Download or read book Echinoderm Paleobiology written by William I. Ausich and published by Indiana University Press. This book was released on 2008-07-18 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.

Download or read book Pal ontology Invertebrate written by Henry Woods and published by Cambridge University Press. This book was released on 1946-01-02 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1946, this is the eighth edition of a book that was first published in 1893. It deals, specifically, with the fossils of the Invertebrata. The general plan is to give, for each group, first, a short account of its general zoological features with a more detailed description of the hard parts of the animals; secondly, its classification and the characters of the important genera, with remarks on the affinities of some forms; and thirdly, a description of the present distribution, and the geological range. The account of each genus is followed by the enumeration of typical species, so as to guide the student in making use of a large collection. The numerous figures help to explain the structure and terminology. For a number of years, Woods' Pal'ontology held its place as the standard work on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: In 1972 Stephen Jay Gould took the scientific world by storm with his paper on punctuated equilibrium. Challenging a core assumption of Darwin's theory of evolution, it launched the controversial idea that the majority of species originates in geological moments (punctuations) and persists in stasis. Now, thirty-five years later, Punctuated Equilibrium offers his only book-length testament on a theory he fiercely promoted, repeatedly refined, and tirelessly defended.
