Marian Murray takes her amateur standing seriously, does not make claims to professional status in her dealing with fossils. Nevertheless, she takes care of certain basics in her pre-hunt prep talk: about ""what fossils are all about,"" a bit of geology, ""the backboneless ones""--invertebrates, plants, the finding and care of fossils. Then come fifty chapters on states, giving the history of fossil finding, the fossil localities, collecting sites according to geologic age. Much of this was covered by Jay Ellis Ransom in Fossils in America (1964) although his listing of states was confined to those with promising sites. The older title need not be replaced unless you wish to extend your collection.
