Fossils, geology and minerals. The highly acclaimed international earth science magazine with over 600 articles and book reviews.
Paul D Taylor and Consuelo Sendino (UK) Spiral structures in nature hold a particular fascination on account of their beautiful yet twisted symmetry. The logarithmic spiral coiling of ammonite shells and rams’ horns, the corkscrew helix of a plant tendril, and the planar spiral of a hurricane when viewed from … Read More
Dr Michał Zatoń (Poland) The Middle Jurassic Bathonian stage, which is preceded by Aalenian and Bajocian and overlaid by the Callovian, was established on the basis of oolitic limestones outcropping at Bath in Somerset. This historical and English connection is a major reason I have chosen the Bathonian as a … Read More
Sebastian Lüning (UK) Morocco is a popular tourist destination. Most people travel to the white beaches of Agadir to sunbathe and relax, to watch the magicians on Djemaa el-Fna square in Marrakech, or to go shopping in the UNESCO-protected Osouk of Fes. However, Morocco has much more to offer. Some … Read More
Rick Day (USA) I found my first Triassic fossil when I was about 15 years old on a backpacking trip in Tule Canyon, Briscoe County in Texas. After setting up camp, I walked over to a small, red-coloured hill. On its slope, I found a small, unusual bone fragment approximately … Read More
Dr Caroline Buttler (UK) It has long been recognised that art and archaeological collections in museums may need specialised conditions and conservation to survive. However, until relatively recently, geological collections have not had the same level of care. Perhaps, it was thought that rocks, minerals and fossils that had already … Read More
Dr Neale Monks (UK) Mosasaurs were large lizards, for a long time assumed to be most related to the modern monitor lizards such as the Komodo dragon, Varanus komodoensis. Certainly they had a lizard-like shape, except that their legs were modified into flippers for steering and their tail was flattened … Read More
Dan Quinsey (UK) Some fossils show evidence of the violent relationships between predator and prey. Below is a brief discussion of a few of such fossils – fossils that seem to preserve the moment when a carnivore has killed its victim or scavenged a dead body for food. Predator: MosasaurPrey: … Read More
Dr Neale Monks (UK) So far our essential collectibles have been invertebrate fossils, remains of animals without backbones such as ammonites and trilobites. Vertebrate fossils are much rarer, and consequently more expensive, the pocket money-priced ones tending to be things like sharks’ teeth or small fragments of reptile bone. Certainly, … Read More
Dr Neale Monks (UK) Gastropods, or snails, are common fossils thanks to their strong, easily preserved external shells. Quite a few fossil gastropods are traded commercially, including members of the genus Turritella. This particular genus first appears in the fossil record during the mid Cretaceous and includes many species still … Read More
Mark Witton (UK) Planet Earth was a busy place 225Ma. The super-continent, Pangaea, in the Northern Hemisphere started rifting, creating the beginnings of the North Atlantic Ocean. Dinosaurs began their campaign for global dominance of Mesozoic terrestrial ecosystems and drove many older reptile lineages into extinction. In the seas, enormous … Read More
The Geologists’ Association have extended their excellent series of geological guides by producing what some people (including me) would think at first was a slightly self-indulgent couple of volumes on ‘Devonshire Marbles’.
Dr Neale Monks (UK) Orthocone nautiloids, loosely referred to as Orthoceras in the trade, are another type of fossil exported from Morocco in large numbers, like the Diacalymene trilobites discussed earlier in this series. Both their common and scientific names refer to the long, narrow, conical shape of their shell, … Read More
Dr Neale Monks (UK) One of the most interesting aspects of fossil collecting is learning about the folklore attached to them, and few fossils rival Gryphaea when it comes to this sort of thing! Known as ‘devil’s toenails’ because of their curves and gnarly shape, during medieval times they were … Read More
Dr Neale Monks (UK) Alongside trilobites, ammonites are among the ‘must haves’ in any palaeontological collection. Professional geologists value them as among the best index fossils, many species having only existed for a relatively brief period of time (often a few tens of thousands of years) but in that time … Read More
Dr Neale Monks (UK). In this series of articles we’re going to be looking at those fossils many people buy rather than collect. This doesn’t mean they’re less interesting of course, but because of the way they’re acquired hobbyists often don’t know much about them beyond what they are and … Read More
Niels Laurids Viby (Denmark) I didn’t go to Florida especially to look for fossils, but I am always looking for opportunities when I am abroad. Being an architect, I actually went there to study houses, in particular, the Art Deco district at Ocean Drive in Miami. However, it seems that … Read More
David Bone (UK) “I have been greatly disappointed … [owing to] sand, sometimes two to three feet in thickness, or the tide not leaving the shore sufficiently exposed; so that a stranger might conclude that there were no fossils to be procured at Bracklesham”. The Sussex geologist, Frederick Dixon, writing … Read More
Richard Edmonds (UK) Between Seatown and Eype, on the West Dorset coast (part of the Dorset and East Devon Coast World Heritage Site), there is a remarkable layer of rock known as the Eype Starfish Bed. This is famous for exquisitely brittle starfish (brittlestars) fossils that are usually preserved on … Read More
Charles Underwood (UK) Fossil sites are generally the result of happy coincidence. It may be that this is the result of natural processes, when the sea or a river has eroded into cliffs of fossil bearing rocks. It could also be the result of human activity, where a quarry opened … Read More
Dr Ross Barnett (UK) The lion (Panthera leo) can rightly claim to be the most oft-invoked animal in all of human culture. Whether praising someone as leonine or lion-hearted, or throwing them to the lions, the second largest of felines has the ability to evoke emotions that the tiger (Panthera … Read More
Dr Neale Monks (UK) While they can be found in many other parts of the British Isles, Scotland is uniquely associated with Palaeozoic fossil fishes. That Scotland’s fossil fishes are so well known is largely thanks to a remarkable man from Caithness, called Hugh Miller. Where scholars had dismissed the … Read More
Robert Sturm (Austria) Microfossils, such as foraminifera, diatoms, ostracods and conodonts, are usually studied using a magnifying glass or under a stereo-microscope. However, nannofossils, such as coccoliths – with sizes measured in micrometres – are way beyond the resolving power of these optical tools. In general, coccoliths are very regularly … Read More
Dean Lomax and Jon Trevelyan (UK) By the early nineteenth century, geology in England had started to appeal to the public at large. For instance, in 1824 the Reverend William Buckland of Oxford University named the first dinosaur (Megalosaurus bucklandii) and, after this, it seems that this awe inspiring group … Read More
Neale Monks (UK) The handful of nautilus species found in seas today are small, retiring animals that scavenge about at night, foraging for carrion and crustacean moults. However, nautiluses were not always so insignificant and, during the first half of the Palaeozoic Era especially, nautiluses were major predators, occupying the … Read More
Ken Brooks (UK) This specimen was found in blue-grey clay on the beach at Bulverhythe, near Bexhill, by a local fossil collector in May 2008 (Fig. 1). This fish, Scheenstia mantelli, was previously known as Lepidotes mantelli (Lepidotes coming from the Greek, ‘lepidotos’, meaning ‘scaly’). Between 145 and 125Ma, there … Read More
Michał Zatoń (Poland) During the 8th International Congress on the Jurassic System 2010, which was held in Shehong, Sichuan Province in China, I had an opportunity to visit several palaeontological museums, exhibitions and geoparks. However, one of them exerted on me incredible impression – the Zigong Dinosaur Museum. The Zigong … Read More
Dr Charlie Underwood (UK) Leaving behind the noise and pollution of Cairo, the drive across the monotonous buff desert comes almost as a relief. After passing through the lush farmlands of the Fayum Oasis and back out onto the desert plains, the first sign of the fossils to come is … Read More
Carl Mehling (USA) Generally, we have no use for it, or at least we convince ourselves we don’t, conveniently ignoring the fact that faeces of one kind or another (even our own) have fertilised our food for millennia. Organic waste products are an integral part of the living system and … Read More
Joan Corbacho and Consuelo Sendino (Spain) Ever since fossils first attracted the attention of mankind, they have been traded and, with the emergence of this commerce, so fossil fakes have appeared. The number of such fakes and their geographical origin has increased with time. On the one hand, this parallels … Read More
Dr David Penney and Dr David Green (UK) This is the second in a series of articles concerning fossils in amber. In the first, we focused on the biodiversity of organisms in the major deposits of the world, including the techniques available for distinguishing genuine fossils from fakes (see Fossils … Read More
