Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Lower Cambrian Edrioasterid, Stromatocystites Walcotti: With One Plate In 1910, while the writer was studying the stratigraphy of western Newfoundland, he was much surprised to find in the Lower Cambrian a number of cystids that seemed to be related to the edrioasterids. These and other Lower Cambrian fossils were collected for the United States National Museum, and the study of the edrioasterids was kindly turned over to the writer by the Secretary of the Smithsonian Institution. In admiration of the long-continued and excellent work which the latter has done on the Cambrian, in the midst of seemingly endless administrative duties, the new species herein described is given the name Stromatocystites walcotti. It was thought at first that these fossils represent a new genus, but after seeing two specimens of Stromatocystites pentangularis from the Middle Cambrian of Bohemia, which are in the Peabody Museum collection in Yale University, it became clear that the Newfoundland form is a species of Stromatocystites. Accordingly, we will begin with a definition of that genus, in the main as given by Pompeckj. Stromatocystites (redefined) d104 fig. 1 E This is a flat and depressed cystid, and it is this spread-out condition that has suggested the name. Theca free, unstalked, subpentagonal in outline, and composed of numerous comparatively large, non-imbricating, and usually five- and six-sided plates. In a theca 35 mm. in diameter there may be 1,000 plates. Upper surface convex, lower one concave. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Early Palaeozoic Biogeography and Palaeogeography written by D.A.T. Harper and published by Geological Society of London. This book was released on 2014-01-27 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Palaeozoic was a critical interval in the evolution of marine life on our planet. Through a window of some 120 million years, the Cambrian Explosion, Great Ordovician Biodiversification Event, End Ordovician Extinction and the subsequent Silurian Recovery established a steep trajectory of increasing marine biodiversity that started in the Late Proterozoic and continued into the Devonian. Biogeography is a key property of virtually all organisms; their distributional ranges, mapped out on a mosaic of changing palaeogeography, have played important roles in modulating the diversity and evolution of marine life. This Memoir first introduces the content, some of the concepts involved in describing and interpreting palaeobiogeography, and the changing Early Palaeozoic geography is illustrated through a series of time slices. The subsequent 26 chapters, compiled by some 130 authors from over 20 countries, describe and analyse distributional and in many cases diversity data for all the major biotic groups plotted on current palaeogeographic maps. Nearly a quarter of a century after the publication of the ‘Green Book’ (Geological Society, London, Memoir12, edited by McKerrow and Scotese), improved stratigraphic and taxonomic data together with more accurate, digitized palaeogeographic maps, have confirmed the central role of palaeobiogeography in understanding the evolution of Early Palaeozoic ecosystems and their biotas.

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.
