Ohio was born billions of years ago, during a time when ancient minicontinents crystallized and then merged into larger continents. Its youth was marked by the coming and going of oceans and the advent of life from ocean to land. The Buckeye State matured when ice sheets scoured its landscape. This storyline is writ large and small in Ohio’s rocks, from its flat till plains to the rumpled and hollowed landscape of the Appalachian Plateau. In Ohio Rocks!, skilled writer and geologist Albert Dickas takes you to some of the state’s most interesting geologic chapters. At Blackhand Gorge the sandy deposits of an ancient sea were cut and sculpted by glacial meltwater. In Scioto County you can trace the margins of a ghost river that flowed before the ice ages. And you can visit the historic Buckeye Furnace, which produced enough pig iron to make Ohio an industrial giant in the nineteenth century. Color photos, maps, and figures compliment the text and further elucidate the geology within the rocks. Ohio Rocks! is the third book in the state-by-state Geology Rocks! series, which introduces readers to some of the most compelling and accessible geologic sites in each state.

Examining in detail at least one amazing fossil site in every state, Albert Dickas clearly explains the critters preserved in the rocks, from sharks and rhinoceroses to trilobites and horn corals. At some sites, you can sift through the shale in search of fossils to keep; at other sites, you can watch professionals excavate museum-quality specimens. The entertaining introduction discusses the history of paleontology, including nineteenth-century arguments about the age of Earth. Dickas also provides a short history of life on Earth, from microbes in 3-billion-year-old chert to massive mammals of the Pleistocene ice ages. Contained within the last 541 million years are the Cambrian explosion, the age of crinoids, and five mass extinctions, including the one that wiped out the dinosaurs. This compendium of 101 fossil sites is the companion volume to the hugely popular 101 American Geo-Sites You've Gotta See, published in 2012. Amply illustrated with photographs and written in a clear yet playful prose, 101 American Fossil Sites You'veGotta See will entertain and inform amateur and seasoned fossil buffs, whether from an armchair or in the field.
