An acclaimed international collection of earth science articles and book reviews on palaeontology, geology, minerals and more
William Bagshaw (UK) White Scar Cave takes its name from the limestone outcrops or “scars” that overlook the entrance. This part of the Yorkshire Dales National Park is dominated by the ‘Three Peaks’ – Ingleborough, Pen-y-ghent and Whernside. Their distinctive shapes are due to their geological structure, which consists of … Read More
Tyler Keillor (USA) In the March 2010 issue of the open-access journal, PLoS Biology, palaeontologist Jeff Wilson and colleagues give an account of a truly unique and amazing fossil discovery. In their article entitled Predation upon Hatchling Dinosaurs by a New Snake from the Late Cretaceous of India, the snake … Read More
Chellai El Hassane (Morocco), Ghanmi Mohamed (Tunisia) and Doblaas Miguel (Spain) The Triassic terrestrial deposits at the northern edge of the High Atlas near Marrakech are mainly represented by thick sequences of massively layered, red sandstone. These are topped by a formation of silt and pink-brown clay containing large deposits … Read More
Adrian Lister (UK) As palaeontologists, we are used to relying on the preserved hard parts of extinct organisms – shells, bones, teeth and so on – to reconstruct their appearance and adaptations in life. The reconstruction of soft tissue relies upon our knowledge of related living forms, plus clues such … Read More
I reviewed another of Gareth T George’s books (The Geology of South Wales: A Field Guide, Ed 2) in the last issue of Deposits (Issue 47). However, given that both these books are well worth buying and reading if you are interested (like me) in the geology of the regions of the UK, I make no apologies.
In this book, Samuel McKie has produced a guide to the most common fossils that can be found at different sites along the Yorkshire coast. And, as he says, it is written by an amateur for amateurs. At the moment, it is set out in black and white, but he is hoping to raise enough money for a full-colour print run.
In these times, when the classic discipline of palaeontology is diminishing, there is a demanding need to inspire the next generation of palaeontologists – and perhaps also to make this field of scientific research more approachable.
It is a wonderful state of affairs that we can not only now write detailed books about planetary geology and geomorphology of the bodies in the solar system, but we can also illustrate them with wonderful photographs.
I quite like regional guides books, even about areas I haven’t been to and am unlikely to visit. That isn’t the case for South Wales, which is one of my favourite areas in the UK for both scenery and geology. Therefore, this guide is another good addition to my collection and will no doubt accompany me soon on another holiday in the Principality.
Almeria is a province in southeast Spain, situated in the furthest southeast part of the Iberian Peninsula. It is a classic area for southern European and Mediterranean Neogene and Quaternary geology.
Ruth Crosbie (UK) The Loch Lomond and the Trossachs National Park has a unique and very visible geological character. This, and the geomorphological processes that have taken place in the area have been fundamental in shaping the outstanding landscape and scenery of the park. Rolling, relatively low-lying farmland along the … Read More
Dr Neale Monks (UK) Most geologists will be familiar with Palaeozoic and Mesozoic cephalopods, but their Tertiary counterparts are much less well known. It isn’t that Tertiary cephalopods are rare as such – at some localities they can be quite common – but their diversity is extremely low. For example, … Read More
Stephen K Donovan (The Netherlands), David AT Harper (UK) and Roger W Portell (USA) In his 2014, Ted Nield (2014) reflects on building stones and what they tell the geologist about where they are. Once upon a time, building stones in Britain were derived locally and told the informed observer … Read More
Dr Clare Torney (UK) The weird and wonderful world of trilobite eyes has been subject to study since the late 1800s, but despite being scrutinised intensively over the decades, we are still left questioning how trilobite eyes actually worked due to the loss of their soft parts (that is, photosensitive … Read More
Steve Koppes (USA) Mendoza, Argentina. The remains of a new ten-meter-long predatory dinosaur discovered along the banks of Argentina’s Rio Colorado are helping to unravel how birds evolved their unusual breathing system. In September 2008, palaeontologists, led by the University of Chicago’s Paul Sereno, a National Geographic Explorer-in-Residence, have published … Read More
Stuart Adams (UK) One of the main attractions of a mineral specimen is its colour and this is often due to the chemical composition of the mineral. Commonly, transition metals (nickel, chromium, copper and so on) give rise to colours that are attractive to the eye. The mineral in question absorbs … Read More
Stephen K Donovan (The Netherlands) It is unfortunate that the miscellaneous holes, pits and depressions produced in wood, rocks and skeletons (bones, shells and tests), both pre- and post-mortem, by a wide range of invertebrates, plants and fungi, are called borings. A less inspiring name for a fascinating suite of … Read More
Dr Sue Beardmore (UK) When most people think of Scotland, the images that come to mind are those of high, heather covered mountains like Ben Nevis, islands like Skye, Arran or Rum, or the endless rugged coastline of the northwest coast. However, there is another half to the country, along … Read More
Luke Sattler (USA) This paper is about an unusual artefact from Wyoming that may have been used by prehistoric people. It has now been studied and the preliminary research results are complete. This ancient scraper is a bifacial, thinned, cortical flaked tool, which means that its flakes were struck from … Read More
Bram Langeveld (The Netherlands) Holland is a small country that lies for the most part below sea level, which can be quite problematical. However, if you are a fossil collector hunting for the fossils of animals from the Weichselian (Last Ice Age) and early Holocene, it is not such a … Read More
Blake Reher (USA) Throughout Roman times, amber was considered the ‘Gold of the North’. It was believed to have medicinal properties that cured arthritis, protected people from suffering mental illness, and healed sore throats. People also thought it had magical properties that gave the wearer bravery. Amber was also a … Read More
Paul D Taylor (UK) People have collected fossils since prehistoric times. In pre-scientific times, a remarkable folklore developed about how fossils originated and their usefulness. Folklore refers to the beliefs – usually non-scientific – and customs of ordinary people. Before the true origin of fossils as the remains of once … Read More
Tanya Piejus (New Zealand) One of New Zealand’s most contaminated sites, the Tui Mine near Te Aroha, is to be cleaned up. The New Zealand budget for 2007 confirmed that NZ$9.88 million was available for the two-year project. The orphan mine site sits on the western flank of Mount Te … Read More
Robert Broughton (UK) In many ways, Britain is the birth-place of palaeontology, and the heady years of the 19th century saw the discovery of creatures that have inspired the imagination of small boys ever since – myself included. I’m talking, of course, about the dinosaurs. A vast plethora of names … Read More
Ruel A Macaraeg (USA) In recent years, a number of ammonite pendants, similar to the one in Fig. 1, have been offered by tribal art dealers. As scientific objects, they offer the interest all fossils – a chance to study the tangible remains of ancient life. Being among the more … Read More
Russell Garwood and Alan Spencer (UK) The Carboniferous Period is a fascinating time in earth history. It spanned 60Ma (359.2 to 299.0Ma), towards the end of the Palaeozoic era, falling between the Devonian and Permian. During the Carboniferous, the supercontinent Pangaea was assembling and the oceans were home to invertebrates … Read More
Steven Wade Veatch (USA) Blue John stone is the name given to banded fluorite found in the Castleton area of Derbyshire in England (Ollernshaw, 1964). It has been prized for centuries. Chemically, it is a calcium fluoride (CaF2) and occurs in distinct bands of different colours: blue, white, purple and … Read More
Dr Neale Monks (UK) Our look at those fossils that commonly bought rather than collected has so far looked at the fossil remains of animals, whether shells, teeth or whatever. But this time we’re looking at a trace fossil; that is, a fossil produced by a living organism but not … Read More
Jerrod Gallup (USA) I got this selenite crystal at the first Pebble Pups meeting I attended. As a result, I researched this crystal and found lots of interesting facts, in particular, that it was very unique. This particular crystal was found in Oklahoma in 1970. In fact, you can go … Read More
Dr David Penney (UK) and Dr Jason Dunlop (Germany) When it comes to fossils, arachnids are not a group that obviously springs to mind. However, with more than 100,000 described living species, Arachnida form the second most diverse group of primarily land-living organisms after the insects. And they probably made … Read More
