Fossils of Iowa, Field Guide to Paleozoic Deposits

This book is a geological field guide written primarily for amateur collectors and students involved with paleontology. One hundred and fifty-eight sites are described through Iowa and adjacent parts of Minnesota and Nebraska, one hundred fifty sites of which were examined in person, Two hundred geological deposits are included, offering a comprehensive look at Paleozoic strata in the area.
Iowa has abundantly fossiliferous deposits from the Ordovician, Silurian, Devonian, Mississippian, and Pennsylvanian Periods. Faunas of the Cambrian and Permian Periods can be found just outside the state borders. Some of the fossil sites are internationally famous.
