Fossils, geology and minerals. Highly acclaimed international earth science blog with over 900 articles and book reviews.
Mugdha Chimote (India) The term ‘Quaternary’ is derived from the Latin word “Quaternarius” (meaning “four”, such that the Quaternary is “the fourth great epoch of geological time” in the now-abandoned system of dividing geological time). It refers to the most recent period of the Earth’s history, covering a span of … Read More
Paul Pursglove (UK) Take a close look at the three teeth labelled A, B and C in Fig. 1. All of these teeth could have been sold by unscrupulous fossil dealers as pterosaur teeth. So, which is the real pterosaur tooth? Pterosaur teeth are very rare fossils and they tend … Read More
If you, like me, spend much of your palaeontological time collecting Jurassic and Cretaceous cephalopods in the south of the UK (ammonites, belemnites and nautiluses), while dabbling with some Silurian orthocones in Shropshire, you will be delighted at the number of books being published recently about this fascinating group of animals.
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.
Mugdha Chimote (India) The Deccan Traps occupy approximately 25% of the total of peninsular India, that is, the triangular shaped landscape of southern India. They traverse the states of Maharashtra, Karnataka, Madhya Pradesh, and Gujarat. The Deccan Traps are currently believed to occupy about 500,000km2 of northwest peninsular India. It … Read More
Mugdha Chimote (India) Introduction Sandwiched between the Arabian Sea to the west and the vast Indian subcontinent to the east, the Western Ghats, a haven for trekkers and travellers, are a 1,600km long range of mountains along western edge of Deccan Plateau. Also known as “Great Escarpments of India”, the … Read More
Carl Mehling (USA) Things aren’t always what they seem. The fluidity of information and the frailties of human memory allow for a lot of corruption. Innocent assumptions are made. Sloppy mistakes take place. Unforeseeable accidents occur. And deliberate subterfuge is always there as an option when these others fail. Throw … Read More
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.
Deborah Painter (USA) “Look over there!” I exclaimed as I stood on the grounds of a manufacturing plant and stared across the tracks of the Atchison, Topeka and Santa Fe Railroad to the east of the plant. I was pointing at several mountains a few kilometres in the distance. “That … Read More
Dr Robert Sturm (Austria) The mineral zircon (more correctly, orthosilicate zircon or ZrSiO4) is an important accessory mineral in various rocks of the earth’s crust, but most of all of igneous rocks with the mineral composition of granite. An accessory mineral is a mineral comprising less than about 10% of … Read More
Dr Robert Sturm Over the last few decades, local amateur collectors, as well as professional palaeontologists, have collected a large number of fossils from quarries and sandpits on the northern margin of the Central European Alps. With the help of these marine and terrestrial fossils, it has been possible to … Read More
Dr Robert Sturm As a result of their great diversity in shape and long-lasting occurrence in earth history (from the Devonian to the Cretaceous), ammonites are equally fascinating objects for the professional and amateur palaeontologist. By definition, ammonites exclusively comprise a group of extinct marine cephalopods that, according to the … Read More
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
Dean R Lomax (UK) A ‘big’ discovery In 2002, a wonderful discovery of a 9.7m-long trackway (ichnofossil) with the tracemaker (a horseshoe crab) preserved was made in a quarry near the village of Wintershof, north of the town of Eichstätt in Bavaria, Southern Germany (Fig. 1). Specifically, the specimen was … Read More
Dr Robert Sturm (Austria) Unlike the British Isles, which contain large swathes of Palaeozoic rocks, Central Europe only features sporadic rock types belonging to this early geological era. Among the most salient geological terrains entirely or partially from the Palaeozoic are the Bohemian Massif, the Central Plateau in France, the … Read More
Robert Sturm The Isle of Skye is a part of the Inner Hebrides in the north-west of Scotland. It has a total area of 174,000 hectares and has an irregularly shaped coastline that is typical of the British Isles. Since the early nineteenth century, the island has become a centre … Read More
Scotland has been the source of many important fossil discoveries, from the first ever soft body parts of the conodont animal, to Devonian fishes and early tetrapods. Yet, there has been little published for the popular market on Scottish palaeontology.
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
This is a lovely little book and something of a departure for Dr Dean Lomax, who, these days is more often seen up to his elbows in ichthyosaur remains. However, this fun little book is rather different. Dean (and ably helped by the artwork of Mike Love) has created a full-colour popup book covering the ancestors of many of our favourite pets.
This is a lovely book – a glorious mixture of a beautiful coffee-table book and an academic treatise of the highest quality. But why microfossils? What is it about them that can create such strong feelings?
Robert Sturm (Austria) During the last few decades, the interest of diverse geosciences has increasingly focussed on the examination of so-called ‘shear zones’, because the displacements between two lithological blocks represent natural ‘laboratories’, within which the phenomena of mineral alteration and deformation are clearly shown for the purposes of scientific … Read More
Jens Lehmann (Germany) Thick-shelled oysters of the species Pycnodonte (Phygraea) vesiculare (Lamarck, 1806) are among the most common fossils of the late Cretaceous period of Europe. They are also known as “thick-shelled mussels” in the popular wisdom and the reason for this name is obvious when you have a look … 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
