This volume, one of two dealing with palaeobotany, covers the first 200 million years of the history of land plant evolution, as represented by the Palaeozoic palaeobotany GCR site network of Great Britain. It demonstrates how the main facets of land plant evolution can be demonstrated at sites in Britain, and how the fossil record can be of value as an evolutionary and environmental indicator of the geological past. This is the first book to place British Palaeozoic palaeobotany sites and their fossil content in a national and international context, showing the value of the palaeobotany resource of Great Britain. In part a conservation tool, this volume also provides the most comprehensive bibliography of the subject yet published, providing an extensive review of the research that has been carried out over the past two centuries.
