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.

Twenty-two reports presenting results from the investigation samples of the Manson impact structure, a crater site in Iowa that was not discovered until 1992. The reports cover a great deal of ground, including geophysical studies of the crater structure, detailed mineralogical, petrological, and ge

An abundance of crinoid ossicles was noted in the early reports of Lower Carboniferous strata of northern Utah and southeastern Idaho. Articulated crinoid cups and crowns, however, were not reported. Collections of the past 50 years and especially the past 15 years have found significant numbers of well-preserved crinoid cups and crowns along with a few echinoids, blastoids, and asterozoans in the Gardison Limestone of the Wasatch Range, Henderson Canyon Formation of the Bear River Range, Wellsville Mountain, and northern parts of the Wasatch Range of northern Utah, as well as in the Lodgepole Limestone of western Wyoming. The purposes of this paper are to describe the crinoids, blastoid, and echinoids from northern Utah and western Wyoming, discuss their relationship to previously described faunas from North America and Europe, and relate their stratigraphic occurrences to conodont zonations and their geographic occurrence to recent interpretations of the regional carbonate facies and tectonic setting.
