For anyone like me who finds the immensity of geological time (‘deep time’) both fascinating and fundamentally difficult – both emotionally and intellectually – this is a great book. Paul Lyle has written it for environmentalists and policy makers to help them explain their concerns and decisions more clearly in the context of geological time, but these are not the only people who should read it.

Normally, I wouldn’t be interested in semi-precious stones and other pretty things. Personally, I prefer grubbing around in the dirt, perhaps for those far more beautiful, elusive and perfectly formed Cretaceous terebratulids or Silurian trilobites. However, some semi-precious stones have the advantage of also providing a tangible link to the ancient history of life that is so fascinating.

The fossil bearing rocks of the British Isles contain the remains of life from the last 2,900Ma and the UK is seen by many as the cradle of modern geology. With this is mind and using a geological map of Britain, palaeontologist Peter Doyle offers a comprehensive guide to UK fossils.

This was the first GA guide I ever bought, and I suspect it is still the best. My copy is more than well-thumbed and water-damaged, through many a happy trip to the south of England to collect, what a friend describes as “white fossils in white rock”.

Graptolites lived in the earth’s oceans from 540 million years ago to 320 million years ago, when they became extinct. The book provides a summary of the state of knowledge relating to graptolites, and the specialists, who contribute to the book, also address the biological questions raised by these fossils, and provide pointers for further research.
