This 1863 work by an eminent geologist remains among the best accounts of an important branch of knowledge. The majority of the text offers an empirical statement of the evidence available in the mid-19th century regarding human existence during prehistoric times. The rest of the book considers the connection between Darwinian theory. 58 figures.

Years ago 13 Crystal Skulls were found in the regions around Central and South America. These enigmatic artifacts have been baffling scholars and researchers ever since. Were they left behind from an ancient civilization or are they here as links to other worlds? Shelley Kaehr, Ph.D., bestselling author of Edgar Cayce's Guide to Gemstones, will explore the Crystal Skull phenomenon and show you how to use the moder-day replicas of skulls in your own healing practice.

This is a book about the dramatic periods in the Earth's history called mass extinctions - short periods (by geological standards) when life nearly died out on Earth. The most famous is the mass extinction that happened about 65 million years ago, and that caused the death of the dinosaurs. But that was not the worst mass extinction: that honour goes to the extinction at the end of the Permian Period, about 250 million years ago, when over 90% of life is thought to have become extinct. What caused these catastrophes? Was it the effects of a massive meteorite impact? There is evidence for such an impact about 65 million years ago. Or was it a period of massive volcanic activity? There is evidence in the rocks of huge lava flows at periods that match several of the mass extinctions. Was it something to do with climate change and sea level? Or was it a combination of some or all of these? The question has been haunting geologists for a number of years, and it forms one of the most exciting areas of research in geology today. In this book, Tony Hallam, a distinguished geologist and writer, looks at all the different theories and also what the study of mass extinctions might tell us about the future. If climate change is a key factor, we may well, as some scientists have suggested, be in a period of mass extinction of our own making.

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).

Originally published in 1885, this work covers details of classical ornamentation of precious and not so precious stones, including rings, signets, cylinder seals, brooches, and other objects in everyday, business and ceremonial use. The author is particularly concerned with the language and symbolism of the decoration.This erudite text covers the history of Western intaglio gems from antiquity to the Renaissance with emphasis on ancient Greek and Roman gems. The second half of the work includes an analysis of copper plate and woodcut engravings concerning ancient artists.
