Fossils, geology and minerals. The highly acclaimed international earth science magazine with over 700 articles and book reviews.
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
John P Green (UK) The Ampthill Clay Formation of the UK, of Late Jurassic (Oxfordian) age, represents a series of highly fossiliferous marine mudstones that form part of the Ancholme Clay Group in North Lincolnshire (Gaunt et al, 1992); but are almost unexposed in the county other than at an … Read More
John P Green (UK) The large, disused quarry at North Ormsby [O.S. grid ref. TF2893], north of Louth in Lincolnshire, displays an important sequence of beds of the Burnham Chalk Formation (Upper Cretaceous, Upper Turonian stage) and, at present, constitutes the best exposure of the beds in the county. Similar … Read More
I don’t normally review BGS memoirs – they are excellent publications, but largely written for the professional or the seriously committed amateur geologist. (I have to admit to owning several, which cover my favourite fossil collecting areas of the UK.) However, this is one ‘Special Memoir’ that I am quite willing to make an exception for.
John P Green (UK) The Early Cretaceous succession in Lincolnshire consists of a series of shallow water marine sandstones, ironstones, clays and limestones, not unlike those deposited elsewhere in the UK during early Jurassic times. In the north of the county, at Nettleton Hill, near the village of Nettleton, minor … Read More
Dr Trevor Watts (UK) In the first part of this article, I discussed the Middle Jurassic environment in the region of Whitby, on the northeast coast of England at the time when dinosaurs roamed there. In Part 2 (see The dinosaur footprints of Whitby: Part 2 – problems matching footprints … Read More
Dr Trevor Watts (UK) In my previous articles in the series, I looked at the environments that allowed dinosaurs to flourish in the Whitby area during the Middle Jurassic and to leave their footprints. Then I considered the factors and problems in trying to match the footprints to particular species … Read More
Dr Trevor Watts (UK) In the first part of this article (The dinosaur footprints of Whitby: Part 1), I considered the immediate surroundings of Whitby as a seemingly unlikely place to find many dinosaur footprints; and I looked at the environments that existed here in mid-Jurassic times; and finally discussed … Read More
Dr Trevor Watts (UK) Introduction I recall reading a sentence in a book some time ago that went something like, ‘Occasionally a dinosaur footprint may be found along the coast.’ In fact, dinosaur footprints are superabundant along the Yorkshire Coast. On a day’s visit to any of 15 or 20 … Read More
The Jurassic Coast Trust is certainly producing some good books these days. I have alraedy reviewed one (The Jurassic Coast: An Aerial Journey through time by Peter Sills) and I think these two might even be better. As is well known, in recognition of its wonderful geology, the coast between Orcombe Rocks in southeast Devon and Old Harry Rocks in south Dorset was granted World Heritage status in December 2001.
Mark Wilkinson (UK) Scotland has a number of sites of historical interest to geologists. I described one of these, Hutton’s Unconformity at Siccar Point near Edinburgh (see Hutton’s unconformity and the birth of ‘Deep Time’). James Hutton described several Scottish unconformities in his book of 1795 and, while the one … Read More
This is an odd little book. Produced by the Craven & Pendle Geological Society and edited by Paul Kabrna, it sets out to cover the geology of Craven Lowlands through a series of chapters written by different contributors.
Jens Lehmann (Germany) Plagiostoma – a record of about 200 million years Are there any boring fossils out there in the ground? I do not think so and to demonstrate this, an “ordinary” fossil find is focussed on here. We are talking about “just” a mussel, but one that belongs … Read More
Jon Trevelyan (UK) This is the much anticipated 4th edition of the GA’s Yorkshire Coast guide and it was well worth the wait. From personal experience, I was aware that the previous editions were extremely good for any geologist – professional, academic or amateur – who is attracted by the … Read More
The long awaited PalAss guide to Wealden fossil flora and fauna has finally arrived and what a magnificent tome it is. At 769 pages and 35 chapters, 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.
Martin Simpson (UK) Newly unearthed documentary evidence substantiates the classic story that Mary Ann Mantell found some worn down Iguanodon teeth in Cuckfield, Sussex, before 1822 in some rocks by the roadside, while her husband Gideon was elsewhere. She was accompanied by a friend and purchased the specimens from a … Read More
Rory Mortimore (UK) Flint in the Late Cretaceous Chalk: links across the European platform In a recent issue of this journal Paul Taylor wrote “We are very fortunate in Britain to host one of the most remarkable deposits in the entire geological record, the Chalk” (Deposits Issue 55, 2018, p.35, … Read More
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.
Jan Willem van der Drift (The Netherlands) Historic finds In 1900, nobody knew what kind of tools man used before the handaxe. Some scholars assumed that early-man used ‘eoliths’ – handy natural forms. That theory turned out to be false. The earliest tools were manmade flakes and cores, and this … Read More
The Jurassic Coast Trust has produced a truly fascinating little picture book illustrating the geology of this World Heritage Site.
It has the shape, form and feel of a holiday souvenir book – the sort you buy in tourist information shops to commemorate your visit with pictures of the sites you didn’t have time to see – and there is also plenty of information for the curious visitor who wants to learn more about the earth science of the area.
Dr Neale Monks (UK) The Gault Clay is an Albian (Lower Cretaceous) deposit of blue-grey clay exposed primarily in Southeast England. At the classic exposure at Copt Point, Folkestone, the Gault Clay is sandwiched between the Lower Greensand underneath and the Upper Greensand on top. It is a stiff clay … Read More
Neale Monks (UK) Alongside trilobites, ammonites are by far the most popular invertebrate fossils. Whether you’re an enthusiastic fieldworker or more of an armchair geologist, chances are that your collection includes a fair number of ammonites of one sort or another. These may well have names and localities, but details … Read More
