Fossils, geology and minerals. The highly acclaimed international earth science magazine with over 450 articles and book reviews.
Those of you who have read a few of my book reviews will know that I love geo-guides to small geographical areas, rather than just the big geological scientific issues. In fact, there are lots of good UK guides like this one, to areas such as Dorset and Yorkshire, and many areas of Scotland and Wales, for example. And this is another excellent example of that genre.
Bob Williams (UK) I first encountered the geological deposit known as the “London Clay” when I accompanied a friend to an exposure of the stuff. He told me that it was good for collecting fossils. It was and I was taken aback by the quality and quantity of fossil material.… … Read More
Richard M Haw (UK) Blue John is a unique variety of blue-purple banded fluorite. Hydrocarbons or oils have been deposited on some of the crystal surfaces while the mineral was forming. These oil layers are partly responsible for giving the stone an alternate blue and white banding, best seen when… … Read More
Jon Trevelyan Britain has a long and proud history of geological museums (and museums that have significant geological collections) dating back at least to early Victorian times. One need only think of William Smith’s revolutionary and magnificent, 1829 Rotunda in Scarborough to understand this (Fig. 1). Here, Smith’s fossils were… … Read More
This is an interesting little booklet and very much a new departure for the Palaeontological Association. You will be aware that I have reviewed several of its many excellent fossil guides in this magazine. However, this recently published tome is somewhat different.
Ray Chapman (UK) The cliff exposure of the Barton Beds between Highcliffe in Dorset and Barton on Sea in Hampshire are the type section of the Bartonian age and are highly fossiliferous. They are Middle Eocene in age and were deposited between 41.3 and 37Ma. They extend to Southampton in… … Read More
Ray Goodwin (UK) It was a hot and sultry summer afternoon in August 1800. A happy crowd was gathered in the small town of Lyme to watch an exhibition of horse jumping in the nearby Rack Field. No one could have guessed that, before the day was out, tragedy would strike… … Read More
Joe Shimmon (UK) With good luck and perseverance, some beautiful fossils can be collected from the London Clay, which outcrops in the south east of England. The phosphatic remains of crustacea, fish and other, rarer vertebrates are well known, and information and images of them are easily accessed, particularly on… … Read More
Fred Clouter (UK) The Isle of Sheppey is situated at the mouth of the Thames estuary and is a part of the North Kent marshes. The north coast of the island has about 5km of London Clay exposures that are highly fossiliferous. The London Clay here was laid down between… … Read More
Michael E Howgate (UK) Back in the days when I gave my ‘Doctor Dinosaur’ talks to museums, school groups and ‘gifted children’, I would take with me: a plaster cast of the Baryonyx claw; a beach rolled Iguanodon vertebra; and, star of the show, ‘a fossilised dinosaur poo’ (which, in… … Read More
Biddy Jarzembowski, Chris Proctor and Ed Jarzembowski (UK) In this concluding part of the mini-series, we show the archaic wet forest at Writhlington (Fig. 9) which is the most familiar palaeohabitat associated with the Carboniferous age of coal. In the absence of flowering plants, the forest was less biodiverse than… … Read More
Biddy Jarzembowski, Chris Proctor and Ed Jarzembowski (UK) In Part 1 of this article (Writhlington revisited (Part 1): A polychrome perspective), we focused on forest arthropods associated with scale trees (Figs. 1 to 4) that were found in the Coal Measures of Writhlington batch, near Radstock, in southwest England. We… … Read More
I always wait expectantly for the publication of a new Palaeontological Association guide to fossils and, when they turn up, I am never disappointed. This is undoubtedly another triumph. This guide attempts to bring the diversity of its flora and fauna together in a single work, for the first time.
Biddy Jarzembowski, Chris Proctor and Ed Jarzembowski (UK) Thanks to ‘King Coal’, it is perhaps all too easy to visualise the Carboniferous Period – and especially the Pennsylvanian Subperiod – in black and white or shades of grey. The Earth’s first tropical forests – which gave us peat which turned… … Read More
I sat down to read this over Christmas and what a good read it turned out to be. The appropriate word is ‘eclectic’ – because Measures for Measure is written for all us with an interest in the industrial history of Great Britain, and its impact on the landscape, economy, social history and culture. It’s a great read as it dots about linking places and ideas together, with the link always being the geology.
P W Forster (UK) I have many years of experience collecting and cutting agates. It was my wife who originally had an enthusiasm for these beautiful semi-precious stones and it was because of her enthusiasm that I developed an interest that has now become an obsessive hobby for the both… … Read More
Byron Blessed (UK) As many of us know, a good day’s fossil hunting rarely stops when we leave the beach. However, many people do not know what to do with a fossil once they’ve found it. So, here are a few pointers in the art of fossil preparation. This article… … Read More
David Mayhew (The Netherlands) When you walk through the countryside,youwill not often come across a vole. However, they are present in most habitats and are one of the most successful groups of small mammals, widely distributed in both Eurasia and North America. Broadly speaking, Voles are blunt- nosed, short-eared, mouse-like… … Read More
Joe Shimmin (UK) The beauty and variety of the microfossils of Folkestone’s Gault Clay cliffs has amazed me ever since I was about 14 years old. At about this time, I had the good fortune to see some samples sent to me by Jim Craig, who I had met at… … Read More
This book is truly sumptuous, and yet is also a comprehensive discussion of William Smith’s maps (including the revolutionary ‘A Delineation of the Strata of England and Wales, with part of Scotland’) and career. It is beautifully produced, printed on quality paper and the full colour illustrations are outstanding.
Joe Shimmin (UK) The Gault Clay outcrop, at Folkestone in Kent, is a wonderful place to find all manner of fossils. Over 100 species of ammonite have been found and there are also barnacles, belemnites, bones (reptile and fish), coprolites, corals, crinoid pieces, crabs, crocodile teeth, fish teeth, gastropods, (deep… … Read More
Jon Trevelyan (UK) In Issue 60 of Deposits, I restarted my occasional series on UK geological museum with a visit to the Booth Museum in Brighton (see Geology museums of Britain: The Booth Museum of Natural History, Brighton). Having more time on my hands than I would like during the… … Read More
This little guide contains excursion guides explaining and exploring the relationship in the UK between hillslope gully erosion and the response by stream and valley systems within the Howgill Fells of Cumbria. The author’s choice of this area rests on the fact that it is one of the most active landscapes in Britain from the point of view of erosion.
Dr Paul D Taylor (UK) Fossil collectors often overlook, or worse discard, bryozoans. There are several reasons: some bryozoans are small and not easily spotted in the field, others are mistaken for non-descript sponges or algae, while bryozoans cemented to the surfaces of other fossils can be cursed for detracting… … Read More
Mary Anning was clearly one of the most significant characters of eighteenth century science and possibly of all time, particularly in the realm of palaeontology. I am not sure that she is quite as unknown (certainly in the UK) as the American author this excellent little biography claims, but she certainly should be better known.
The 71st GA guide has been published and what a good one it is too. It’s not really my area (I prefer palaeontology) and covers quite a specialist subject, but this is certainly interesting. And this is surely the point of GA guides – to cover topics that other publishers might be reluctant to consider.
Dean R Lomax (UK) Introduction Ichthyosaurs are extinct marine reptiles that superficially resemble dolphins and sharks, but are neither. They are most definitely not ‘swimming dinosaurs’. In fact, they were fully aquatic marine tetrapods that lived in the seas, while their more famous counterparts – the dinosaurs – roamed the… … Read More
David M Martill (UK) After several gruelling years of working in the sticky wet Jurassic clay pits of the Peterborough district for their gigantic marine reptiles and even more massive fishes, it was a refreshing change to fly south and investigate the sun-baked Caatinga of South America. The Chapada do… … Read More
Jens Lehmann (Germany) The recent find of a big slab of Early Cretaceous lumachelle limestone of the Wealden facies containing a bone (Figs. 1 and 2) made for a time-consuming and technically ambitious preparation process. (Lumachelle limestone is a compact limestone or marble containing fragments of shells, encrinites and other… … Read More
Jens Lehmann (Germany) Plate tectonics drove the continent-continent collision of Euramerica and Gondwana, roughly 280 to 380mya. This mountain-building phase of the late Palaeozoic era is referred to as the Variscan Orogeny and eventually formed the supercontinent Pangaea. This was largely complete by the end of the Carboniferous and many… … Read More
