By examining radiocarbon (C-14) dating--the best known of these <br /> methods--and several other techniques that geologists use to decode the distant <br /> past, Macdougall unwraps the last century's advances, explaining how they reveal <br /> the age of our fossil ancestors such as &quot;Lucy,&quot; the timing of the dinosaurs' <br /> extinction, and the precise ages of tiny mineral grains that date from the <br /> beginning of the Earth's history. In lively and accessible prose, he describes <br /> how the science of geochronology has developed and flourished. Relating these <br /> advances through the stories of the scientists themselves--James Hutton, William <br /> Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson--<br /> Macdougall shows how they used ingenuity and inspiration to construct one of <br /> modern science's most significant accomplishments: a timescale for the Earth's <br /> evolution and human prehistory.<br /> <br /> Table Of Contents<br /> <br /> List of Illustrations ix<br /> Acknowledgments xi<br /> No Vestige of a Beginning ... 1<br /> Mysterious Rays 21<br /> Wild Bill's Quest 45<br /> Changing Perceptions 72<br /> Getting the Lead Out 101<br /> Dating the Boundaries 131<br /> Clocking Evolution 159<br /> Ghostly Forests and Mediterranean Volcanoes 190<br /> More and More from Less and Less 219<br /> The Geological Time Scale 239<br /> Periodic Table of the Chemical Elements 241<br /> Additional Notes 245<br /> Glossary 251<br /> Resources and Further Reading 257<br /> Index 265 <br /> <br /> Product Details<br /> <br /> * ISBN: 0520249755<br /> * ISBN-13: 9780520249752<br /> * Format: Hardcover, 278pp<br /> * Publisher: University of California Press<br /> * Pub.
