Amazon.com description: Product Description: This beautifully illustrated book describes one of the most famous fossil deposits known: the Hunsrück Slate of Germany. These spectacular fossils, in which not just the hard parts but also the soft-tissues of the animals are preserved in pyrite in many cases, provide the most complete record available of life in the Devonian seas. The book provides the first comprehensive account of these remarkable fossils to be published in English. It is written in an accessible style, and is extensively illustrated with photographs and X-radiographs of many of the finest specimens. The book reviews the different plant and animal groups, and includes a complete taxonomic list and comprehensive bibliography. It will be of most value to researchers and graduate students in palaeontology, geology and evolutionary biology, but it will also be of interest to amateur collectors and natural historians.
