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.

Over a period of 20 years, Ian Tyler has written a series of books on the metalliferous mining industry of the English Lake District and this has clearly been a significant labour of love for him. Unfortunately, Roughton Gill and the Mines of the Caldbeck Fells is his last – the result of the sad loss of his wife and collaborator in this project. However, he has now created an extraordinary record of the geological economic activity in this part of the world.

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.

This is a comprehensive account of the minerals found in the British Isles (including Ireland) and the surrounding islands. At over 600 pages and illustrated throughout by over 550 images (mostly in colour), the book provides exhaustive coverage of the remarkably wide range of minerals found in this part of the world.

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.

The author, John L Morton, certainly came to popular geological publishing by an interesting and circuitous route. Trained as a pilot, became the district commissioner for scouts in Horsham and, on retirement, studied a BSc in, among other things, geology. In 2001, on the strength of this book on William Smith, he was elected a Fellow of the Geological Society.

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.

There are several passions in my life – geology and geomorphology being a couple and hillwalking being another. And it doesn’t take much to see that that these go together rather well. Over the last few years, a number of great leaflets, often laminated, have been produced setting out UK geological walks and these are some more good ones.

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.

Dorling Kindersley is well-known for producing popular reference media for beginners and enthusiasts. Its Eyewitness Guides to fossils and rocks and minerals, for example, along with their later addition, the Eyewitness Handbook of fossils, certainly makes a useful starting point for anyone new to geology or palaeontology.
