Fossils, geology and minerals. Highly acclaimed international earth science blog with over 850 articles and book reviews.
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
Steve Koppes (USA) A lanky predator roamed South America in search of prey as the age of the dinosaurs began, approximately 230Ma. This dinosaur, named Eodromaeus (the “dawn runner”), sported a long neck and tail, and weighed only 4.5kg to 6.8kg. A team of palaeontologists and geologists from Argentina and … 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
Stephen K Donovan (The Netherlands) A misconception shared by many non-palaeontologists is that fossils are rare. For example, when governments pass legislation to protect their fossil heritage, they are stopping the export of complete and well-preserved specimens, such as those of Mesozoic dinosaurs, hominids and Ice Age mammoths. There can … Read More
Dr David Penney and Dr David Green (UK) It is almost two decades since the original blockbuster movie, Jurassic Park, brought the existence of fossil insects in amber (fossilised tree resin) into the limelight. Since then, numerous books and research papers have been published. Fossiliferous amber deposits are still being … Read More
Dr Steven C Sweetman (UK) Most palaeontologists now accept that birds are descended from non-avian dinosaurs and are therefore the only living representatives of otherwise terrestrial animals that ruled the world during the Mesozoic. That being the case, the Cuban bee hummingbird, which measures just 5cm in length and weighs … Read More
Brian Day (UK) I first got interested in Fossils by accident… I was an engineer by profession and worked lots of hours travelling to Germany etc. So I took my family on holiday at every opportunity. My family comprised my Wife, Son and Daughter. I enjoyed an early morning walk … Read More
The Jurassic/Cretaceous boundary interval is represented in Lincolnshire by the Spilsby Sandstone Formation, a shallow water marine deposit that spans the Volgian stage of the Jurassic to the Berriasian stage of the Cretaceous (Hopson et al. 2008). The ammonite faunas of this formation are of particular interest, exhibiting affinities with correlative forms in both Russia on the Siberian plain, as well as Greenland and Canada (for example, Casey, 1973; Mikhail Rogov, personal communication 2015).
Back here in the United States, the blockbuster movie Jurassic World still plays in theatres, while presidential candidates hit the campaign trail. This confluence of events reminds me of a crazy idea I had back in 1992, a couple years after Michael Crichton published his novel. This tongue-in-cheek essay explores the idea to its full absurdity.
John P Green (UK) As many amateur and professional palaeontologists are aware, ichthyosaurs are well-known aquatic reptiles from the Mesozoic era, which are especially common in Jurassic marine deposits in the UK. They are particularly conspicuous in the Charmouth and Whitby Mudstone Formations of the Lias (Lower Jurassic), as well … Read More
Ryan Clayton (UK) I have always been curious about footprints and trackways made by prehistoric animals, especially dinosaurs, due to the concept that the ground has captured the process of an animal, which is now long dead and their species extinct. I find it even more exciting when the creature … Read More
Martin I Simpson (UK) The details of how the nineteenth century Sussex surgeon and palaeontologist Gideon Mantell came to acquire, describe and announce to the world a new fossil herbivorous reptile, later to be christened Iguanodon and to be included in Owen’s Dinosauria, have been merged together to form one … Read More
