Fossils of the Upper Ordovician Platteville Formation in the Upper Midwest USA: An Overview This 328-page hardback volume printed by the Illinois State Geological Survey includes over 1200 full-color, high-resolution photographs of fossil specimens collected from the Upper Ordovician Platteville Formation in the Upper Midwest USA. The described and illustrated fossil assemblage includes exceptionally well-preserved sponges, corals, bryozoans, brachiopods, polyplacophorans, gastropods, bivalves, rostroconchs, cephalopods, trilobites, ostracodes, echinoderms, graptolites, cornulitids, hyolithids, macroalgae, and a wide variety of trace fossils. This overview is directed to students, collectors, and professional paleontologists. Each chapter begins with a brief introduction to the morphological terms used to describe the various fossil groups, followed by systematic descriptions, remarks, and occurrence information. This overview can serve as a starting place and a source of inspiration for future paleontological research on the fossils of the Platteville Formation, offer insights regarding past climate and the environments in which life thrived, and ultimately shed light on the history of life on our planet.
