I have written many admiring reviews of Dunedin’s books, and this is another one. OK – I like fossils, but it is always nice to have a brief but informative guide to the actual science behind one’s finds.
Andy Gale’s update of his guide to the Isle of Wight (this is the sixth edition) is an important change to an already excellent geological guide. The Geologists’ Association has been updating several of its guides – using a modern format, and providing better colour pictures and diagrams – and this is another great example.
So, Palass has published another of its excellent field guides, this time to the fossils from the Lias of the Yorkshire coast. Readers of this magazine will know that I have a soft spot for these guides.
