Opis

Life in Stone is the first booik to focus on British Columbia's fossils. Each of its chapters is written by a specialist for a general audience, and each is devoted to a separte fossil group that is particularly well represented in the province.British Columbia is a vast storehouse of fossils, many of which date back a billion years. Thousands of exposures of sedimentary rocks throughout the province contain fossil shells, scales, bones, teeth, and leaves. Some of the fossils are large and striking, among them the bones of mammals and reptiles, entire ammonoids, and complete fishes and fern fronts. But even a small fossil such as a common shell, a plant fragment, or a bit of bone becomes a unique icon once its nature and age are made clear.
