The Dalradian is a geological term describing a series of metamorphic rocks, typically in the high ground lying southeast of the Great Glen of Scotland. It was named after the old Celtic region of Dál Riata (Dalriada) by the geologist, Sir A Geikie, in 1891, and the term now covers a range of metamorphic rocks.

Once upon a time, I would have said that the only reason to buy this sort of guide is to look at the (black and white) photos of dinosaurs and their bones, and learn about the terrestrial life of what is now the Isle of Wight. However, this is obviously wrong. Of course it is possible for amateurs, as well as professionals, to find dinosaur bones on the beaches of the island.

The Scottish Borders region is famed for their frontier history, and attendant myths and ballads. This book is concerned with their more ancient geological history, which is revealed by its rocks. These indicate that the area was once on the edge of a huge ocean – the Iapetus – which met its end between the inexorable crush of tectonic plates.

I have learned to like amber and this certainly isn’t the first book on the subject I have reviewed. I make no apologies – it’s a fascinating subject. However, if you like fossils in amber, you should definitely get this book. But, if you don’t like creepy-crawlies, perhaps you shouldn’t – as it’s the pictures that make it a resounding success.

There are many good guides the geology of the Lake District and this is no exception. It is an illustrated guide to the region’s rocks and an introduction to the common rock types to be found, largely through the use of colour photographs. It also explains how they fit in with the Lake District’s geological history.

English Wealden fossils

When the long awaited PalAss guide to Wealden fossil flora and fauna finally arrived, it was apparent that it was a magnificent tome. It is, by far, the most ambitious and complete of their guides, covering various vertebrate groups, together with invertebrates, plants and stratigraphical descriptions of what can be found on the coast and in the quarries of southern England and the Isle of Wight.

The first ever fossils I collected were from the spoils tips of the two coal mines in Aberdare, South Wales. Alas, these and most other such spoil tips have been landscaped and covered over. Clearly this was both inevitable and desirable after the closure the UK coal industry, but it is a shame for those of us who love Carboniferous Coal Measures plant fossils.

Recently, the Geologists’ Association kindly sent me three of their new guides to review, and I chose to review Alderney and La Hague: an Excursion Guide first, for some very personal reasons. I remember fondly my visits as a child to Alderney, and my extensive civil engineering works on Corblets beach, building dams of sand to capture the water flowing across the sand into the Race of Alderney.

Fossils of the Oxford Clay was the fourth published guide by PalAss and covers the eponymous Jurassic Oxford Clay, which has been the major source of brick clay in the UK, notwithstanding the closures of clay pits in the Peterborough area over the years since this was published.

Iceland seems to set the hearts of certain geologists racing and, reading this field guide, it is abundantly clear why. Set out in this concise and authoritative book is the evidence of how this strange piece of rock – astride the Mid-Atlantic Ridge – is a “natural laboratory”, where the earth sciences can be watched in dramatic real-time.

Anglesey contains a fascinating variety of rock types and geological structures, best exposed in a magnificent coastline. The bedrockgeology of Anglesey comprises a complex collage of igneous, sedimentary and metamorphic rocks that were formed between 300 and 650 million years ago.

There is very little on the fossils of the UK Permian, so this guide was a welcome addition, when it was published in 1988. This was the third of 1988, Palass’s guides to (usually) UK fossils, which the professional and amateur can use to identify and learn about the fossils they have found or want to find.

In this book, you will travel back millions of years in time, as though a time-traveller, to join wildlife safaris and visit ancient environments teeming with life. As the fossils come alive, you will experience and understand the fauna, flora and landscapes seen at localities in the geological past of Scotland.

Most PalAss guides, making up its wonderful library of guides to fossils, are about UK fossils. This is the only one that concentrates solely on non-UK geological formations. It is about two formations found in northeast Brazil and so is a complete departure from the usual format.

I like the GA guides. They are excellent resources for amateurs and professional geologists alike. I frequently browse mine, planning geological trips I will probably never take, because I live in geological unexciting London. Therefore, imagine how pleased I was to receive a GA guide to the Great Metropolis to review.

It might come as a surprise to the vast majority of the UK population (and probably anyone reading this elsewhere), but this country is a great place for dinosaurs. In fact, it is one of the most important places for Lower Cretaceous dinosaurs, whose remains have been found on the Isle of Wight and in the Weald. A possible Triassic dinosaur has also been found in Morayshire, Scotland, and there are plenty more from the entire length of the Jurassic.

I have a soft spot for PalAss guides and have reviewed several in the past. As a collector myself, the amount of information about the relevant fossils is second to none, with black and white photos and descriptions of virtually everything the amateur or professional palaeontologist might need.

This latest publication from the British Geological Survey follows the success of its earlier publication, ‘Exploring the Landscape of Assynt’. It consists of a special pack containing both an explanatory booklet and a new 1 : 25,000 scale geological map of the Charnwood Forest and Mountsorrel area.

Like others in the series, Fossils of the Gault Clay has the usual excellent black and white photographs of beautifully prepared specimens. Each chapter is authored by a specialist in the relevant subject, containing an introduction, followed by detailed systematic descriptions of each specimen.

Just a couple of days before the Covid-19 lockdown, I was with friends at Tidmoor Point collecting wonderful pyrite ammonites from the Oxford Clay with this excellent guide to the South Dorset Coast. The South Dorset Coast runs from the West Fleet (of Chesil Beach fame) to and including the Isle of Portland.

The blurb for this book states that it will “profoundly affect the way paleontologists and climatologist view the lives of ancient mammals”. However, not being either a (professional) palaeontologist or climatologist,but having read it with interest, I am not sure that is correct. Anyone with an active interest in what the interactions of ancient mammals and their environments tell us about the presentand future will be interested in this well-written and engaging book.

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.
