In the spring and summer of 2000, geologists working for the Tennessee Department of Transportation made an extraordinary find as they examined soil at a routine road construction project: the digging at Gray, Tennessee, had uncovered a fossil site containing bones that would turn out to be at least five million years old. Harry Moore and his colleagues, along with researchers from the state and the University of Tennessee, were stunned as they unearthed the fossilized remains of tapirs, elephants, rhinoceroses, alligators, and other long-dead animals. What was at first thought to be an Ice Age site ten to twenty thousand years old proved to be much, much older. The Bone Hunters recounts the fascinating details of a remarkable chance discovery. In his engaging firsthand account, Moore writes of the people behind the excavation of the site and how their efforts helped save valuable artifacts for ongoing study. Numerous photographs capture the excellent condition of fossils at Gray. Moore also describes the contours of what the ancient landscape may have looked like and details the governmental action that ultimately preserved this Tennessee treasure. Harry Moore manages the Tennessee Department of Transportation's Geotechnial Engineering office in Knoxville. His previous books are A Roadside Guide to the Geology of the Great Smoky Mountains National Park, A Geologic Trip Across Tennessee by Interstate 40, and Discovering October Roads: Fall Colors and Geology in Rural East Tennessee (co-written with Fred Brown).

Organized geographically by county and accompanied by site maps and photographs, this guide describes where to go and what you'll find there.

Die Entdeckung der Neandertaler vor rund 150 Jahren hat immer wieder fur aufgeregte Diskussionen in Archaologie und Anthropologie gesorgt. Die Fragen, welchen genetischen Beitrag sie zur Entwicklung des heutigen Menschen geleistet haben oder warum die Neandertaler letztendlich ausstarben, sind bis heute ungeklart. Dieser Streit in der Wissenschaft, die unterschiedlichen Interpretationen der Fossilien gestern und heute sowie die Evolution und Kultur des Neandertalers werden erstmalig vollstandig und mit attraktivem Bildmaterial dargestellt. In einem aktuellen Anhang des Neanderthal Museums wird uber die spektatkularen Neufunde im Neandertal und von anderen Orten Deutschlands berichtet."

Carbon plays a fundamental role on Earth. It forms the chemical backbone for all essential organic molecules produced by living organisms. Carbon-based fuels supply most of society's energy, and atmospheric carbon dioxide has a huge impact on Earth's climate. This book provides a complete history of the emergence and development of the new interdisciplinary field of deep carbon science. It traces four centuries of history during which the inner workings of the dynamic Earth were discovered, and documents extraordinary scientific revolutions that changed our understanding of carbon on Earth forever: carbon's origin in exploding stars; the discovery of the internal heat source driving the Earth's carbon cycle; and the tectonic revolution. Written with an engaging narrative style and covering the scientific endeavours of more than a hundred pioneers of deep geoscience, this is a fascinating book for students and researchers working in Earth system science and deep carbon research.

Distant relatives of modern lobsters, horseshoe crabs, and spiders, trilobites swam the planet's prehistoric seas for 300 million years, from the Lower Cambrian to the end of the Permian eras--and they did so very capably. Trilobite fossils have been unearthed on every continent, with more than 20,000 species identified by science. One of the most arresting animals of our pre-dinosaur world, trilobites are also favorites among the fossil collectors of today, their crystalline eyes often the catalyst for a lifetime of paleontological devotion. And there is no collector more devoted--or more venerated--than Riccardo Levi-Setti. With "The Trilobite Book," a much anticipated follow-up to his classic "Trilobites," Levi-Setti brings us a glorious and revealing guide to these surreal arthropods of ancient Earth.
Featuring specimens from Bohemia to Newfoundland, California to the Tucson Gem and Mineral Show, and Wales to the Anti-Atlas Mountains of Morocco, Levi-Setti's magnificent book reanimates these "butterflies of the seas" in 235 astonishing full-color photographs. All original, Levi-Setti's images serve as the jumping-off point for tales of his global quests in search of these highly sought-after fossils; for discussions of their mineralogical origins, as revealed by their color; and for unraveling the role of the now-extinct trilobites in our planetary history.
Sure to enthrall paleontologists with its scientific insights and amateur enthusiasts with its beautiful and informative images, "The Trilobite Book" combines the best of science, technology, aesthetics, and personal adventure. It will inspire new collectors for eras to come.

South America is home to some of the most distinctive mammals on Earth—giant armadillos, tiny anteaters, the world's largest rodent, and its smallest deer. But the continent once supported a variety of other equally intriguing mammals that have no close living relatives: armored mammals with tail clubs, saber-toothed marsupials, and even a swimming sloth. We know of the existence of these peculiar species thanks to South America's rich fossil record, which provides many glimpses of prehistoric mammals and the ecosystems in which they lived. Organized as a "walk through time" and featuring species from 15 important fossil sites, this book is the most extensive and richly illustrated volume devoted exclusively to the Cenozoic mammals of South America. The text is supported by 75 life reconstructions of extinct species in their native habitats, as well as photographs of fossil specimens and the sites highlighted in the book. An annotated bibliography is included for those interested in delving into the scientific literature.

The astonishing biography of a mineral that can sustain our world- or destroy it
Uranium occurs naturally in the earth's crust-yet holds the power to end all life on the planet. This is its fundamental paradox, and its story is a fascinating window into the valor, greed, genius, and folly of humanity. A problem for miners in the Middle Ages, an inspiration to novelists and a boon to medicine, a devastat-ing weapon at the end of World War II, and eventually a polluter, killer, excuse for war with Iraq, potential deliverer of Armageddon and a possible last defense against global warming-"Uranium" is the riveting story of the most powerful element on earth, and one which will shape our future, for better or worse.
