Increasingly nowadays, the London Clay Formation is becoming a favourite hunting ground for fossils and several good books have been written about it. This guide, written by eminent plant palaeobotanist, Margaret Collinson was the first published by PalAss in its library of guides to (usually) UK fossils for professionals and amateurs.
There are only a few good books on the London Clay and its fossils, but this little guide from the Geologists’ Association is a good start for beginners, children and teenagers. Rockwatch, which published this guide, is the national geology club for young people, the junior club of the GA. Having said that, this guide does not dumb down the information it contains.
The very small number of books published by the Medway Fossil and Mineral Society are without exception, wonderful and this is probably the best. And, there are very few guides on the London Clay. Therefore, this guide is invaluable and more than welcome.
