A survey of representative trilobite species from North America. It includes meticulous line drawings of 42 species, with information for each concerning classification, geologic range, and geographical distribution. Descriptions of probable life style, similar species, interesting features, etc. are also given. The 8 page, illustrated Introduction includes discussions of trilobite anatomy, growth, vision, lifestyles, locomotion, feeding, classification, and extinction. A brief "suggested reading" list is also offered.

A photographic guide to Oklahomas 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 Oklahomas 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.

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.
