National Audubon Society Field Guide to North American Fossils

This, the first all-photographic field guide to cover fossils found throughout North America north of Mexico, includes nearly 500 full-color photographs identifying corals, trilobites, shells, teeth, bones, as well as fossil-bearing rocks and outcrop formations. The descriptive text includes information on size, geological period, geographical distribution, and ecology of the animal or plant before it was fossilized. In addition, the book provides lists of Geological Survey offices and major fossil collections, a geological time chart, and a guide to collecting and preserving fossils.
