I have stood several times in front of an (apparently) plain white, chalk cliff-face along with others, while Prof Mortimore discussed the implications of what we were seeing. And, every time, I left not just thinking but knowing this was the most fascinating piece of geology I had ever seen. That is it the man.

This is another of the GA’s short guides, being only 21 pages long and therefore easy to put in a cagoule pocket. Importantly, the five excursions described in the guide are centred on the city of Plymouth. Therefore, the logistics necessary to visit the itineraries should be relatively easy.

In this second edition, Dougal Jerram has revised and updated the 2001 version, first published by Alwyn Scarth and Jean-Claude Tanguy. This is to reflect modern research and understanding of Europe’s volcanoes of the last 10,000 years (active, dormant and extinct).

West Dorset is rightly famous for its fossils, but few people visit its wonderful, fossiliferous cliffs to look at them as landforms, rather than as an endless source of ammonites and belemnites. This guide does just that and, covers a series of itineraries in the context of landform type.

This GA guide is intended as a major guidebook to the exposures of highly significant Precambrian, Carboniferous and Permo-Triassic sediments, through to Jurassic rocks of the East Midlands. Personally, it is an area I only partly know (I know Edale in the Peak District quite well) and, for that reason, is an interesting set of locations for me.

After having favourably reviewed the first two books in this three part series, I must admit I was very much looking forward to the publication of this last one. And, of course, I wasn’t disappointed. This is the third in a series of guides to safe and responsible fossil collecting along (this time), the East Dorset coast from the Chalk cliffs at Bat’s Head, across what are some of Dorset’s more remote coastal locations, to Hengistbury Head.
