Book excerpt: Forty-five species of lower Middle Ordovician trilobites, including six new genera and thirty new species, are described and illustrated from the extensive collections in the United States National Museum. Most of these species occur in beds whose age and correlation have been a matter of controversy for more than a decade. The stratigraphic evidence afforded by the trilobites lends strong support to regional stratigraphic interpretations of the lower Champlainian beds in the Appalachian Valley, which have been worked out by G. Arthur Cooper and the writer fromdetailed study of brachiopod faunas and from physical stratigraphic studies. The trilobites, like brachiopods, are not so restricted in their facies distribution as are many groups of invertebrate fossils. Hence they are very useful in establishing contemporaneity of dissimilar facies. In this paper only the more common trilobites are described. The principal purpose of this study is to make available for biostratigraphic use a number of trilobite species, most of which have been confused or misidentified previously.

This book was released on 2018-02-24 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Some Trilobites of the Lower Middle Ordovician of Eastern North America This paper is concerned primarily with the trilobites of the lower part of the Middle Ordovician of the Appalachian Province. It'is based upon collections made by the writer during expeditions to Pennsylvania, Virginia, and Tennessee, the cost of which was de frayed by the Shaler Memorial Fund at Harvard University. These trips were made in 1917, 1918, and 1921, and although primarily for the study of the stratigraphy of the Ordovician formations of the region, it soon became obvious that the perplexing problems presented could not be solved until the faunas were described.

This book was released on 1989 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trilobites from the Upper Cambrian to Lower Ordovician Survey Peak, Outram and Skoki formations at Wilcox Pass, Alberta, comprehensively described in this report, belong to 48 genera. One new genus and six new species are described, and type material for seventeen previously described species from corresponding strata elsewhere in the Rockies is redescribed or re-illustrated. This report establishes a biostratigraphic framework for the Wilcox Pass sequence, from the highest part of the Upper Cambrian Trempealeau Series through the entire Lower Ordovician, based on trilobite zones.

Available in PDF, EPUB and Kindle. Book excerpt: A photographic guide to Oklahoma's Devonian trilobites. The geological history of Coal County, Oklahoma. Descriptions of rock formations where trilobites are found. Excavation and restoration of trilobites. A photographic atlas of the Lower Devonian trilobites of Oklahoma, with helpful information to aid in their identification. Trilobites are a well-known fossil group, possibly second most famous only to dinosaurs. With their easily fossilized exoskeleton, they left an extensive and diverse fossil record. They began a drawn-out decline to extinction during Late Devonian time, when all but one of the trilobite orders died out. This meticulously researched reference guide is a photographic atlas and descriptive compendium on the trilobites of Coal County, Oklahoma. The species described lived during the Lower Devonian in a shallow tropical ocean that had advanced over the landscape of North America. More than twenty species are exquisitely preserved in Oklahoma's limestone rocks. Each species is carefully illustrated, including thorough descriptions, so that those familiar and unfamiliar can understand and appreciate these amazing creatures. The most current scientific research on these trilobites is also included. For those wishing to pursue a deeper interest in trilobites, a comprehensive bibliography lists hundreds of sources of information for further study.

Available in PDF, EPUB and Kindle. Book excerpt: "Trilobites are the most lifelike of fossils--many well-preserved specimens belie their great antiquity and seem almost ready to arch their bodies, peer about with their compound eyes, and crawl forward as if to complete a journey that was interrupted hundreds of millions of years ago."--from the Foreword"New York State is and has long been a magnet for trilobite hunters.... New York's trilobites were among the first illustrated fossils in North America.... Many outstanding localities in New York State, from the majestic Ordovician limestone bluffs of Trenton Falls, to the Silurian beds in the great gorge of Niagara River, to the Devonian shale cliffs of Lake Erie, continue to yield abundant and spectacular trilobite fossils. New York strata have also yielded more trilobites with preserved appendages and other "soft parts" than almost any other region of the world.... Spectacular, ornate trilobites from New York ranging from a few millimeters to nearly a half meter in length, are featured in museums all over the world."--from the PrefaceThis superbly illustrated book reviews the trilobite fossils found throughout New York State, including their biology, methods of taphonomy (preservation of specimens), and the broader Paleozoic geology of the state. A general chapter on the geology of New York State places the importance of these now-extinct invertebrate marine animals into context. Sixty-seven line drawings and 175 black-and-white photographs illustrate individual species, many represented here by type specimens, and display the eerie beauty that has made New York State trilobites favorites of collectors the world over.
