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
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
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
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
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
Terence Collingwood (UK) Recently, I was lucky enough to unearth a prize find – a 40-million-year-old, spider-like insect perfectly preserved in amber. I found the valuable harvestman in a piece of prehistoric amber and considered it to be of such scientific interest that I donated it to the National History … Read More
Stephen K Donovan (The Netherlands) The last weekend in September 2013 was sunny after more than two weeks of grey skies, rain and even some fog. Saturday was spent as planned, moving bookcases ahead of Karen’s insatiable paintbrush, the walls changing from lime green to white as she progressed. Sunday … Read More
Nigel R Larkin (UK) A recent find from Lower Jurassic marine deposits on the Dorset Coast consists of a curious association of bones and bone fragments that have so far eluded identification, despite being inspected by some top palaeontologists. Is it a shark? Not according to some shark specialists. Is … Read More
Dean Lomax (UK) A Lagerstätte is a sedimentary deposit that exhibits exquisite fossil richness, detail and/or completeness, often preserving fine details, including soft parts, which wouldn’t normally be found as fossils. There are two main types of fossil Lagerstätten: concentration Lagerstätten, which simply consists of large concentrations of fossils found … Read More
James O’Donoghue (UK) It’s a Welwitschia! Nestling among 280 million year old fossil tree trunks, this is the rare plant I have been searching for. Two wonders of the natural world – the living, sprawling Welwitschia and the ancient, petrified trees – have fortuitously come together here in Namibia. Separated … Read More
Martin Simpson (UK) The Isle of Wight has long been regarded as a world famous fossil locality. It is now called Dinosaur Island, with no less than 29 different species having been found along the southern coast. Indeed, it has recently been ranked in the top seven dinosaur localities worldwide. … Read More
Neil Clark (UK) The existence of dinosaurs in Scotland is not something that is generally well known. Yet, there are at least three different families represented from fossil bones and a number of different footprint types from the Middle Jurassic. Of the bones, there is a sauropod, a thyreophoran, a … Read More
Stephen McLoughlin (Sweden) South of the craggy limits of Patagonia, Africa and Tasmania, and beyond the piercing gales of the roaring forties and the furious fifties, lies Antarctica – the last great continent on Earth to be explored. Straddling the South Pole, it lies frozen in a winter that has … Read More
Robert Broughton (UK) The end Permian mass extinction occurred 251mya and marked the end of the Palaeozoic era. The loss of life is currently estimated to consist of 95% of the marine fauna and around 70 to 77% of the known terrestrial fauna (where the fossil record is inevitably less … Read More
Dr Neale Monks (UK) While arthropods and roundworms exceed the phylum Mollusca in terms of species, molluscs hold their own when it comes to anatomical diversity. There may be well over a million species of arthropod, but crabs, spiders and bees are all obviously related, sharing the same multi-limbed body … Read More
Dick Mol (Netherlands)and Wilrie van Logchem (Netherlands) Somewhere around the Dutch coast, a mammoth herd, led by an experienced matriarch strolls along a trail on the cold, dry and treeless steppe – the mammoth steppe – typified by tall, tough grasses and Artemisia. The impressive herd numbers about thirty animals, … Read More
Benjamin Kear (Australia) and Georgios Georgalis (Greece) Most people are familiar with the famous giant tortoises of the Galapagos Islands – isolated oddities evolving in the absence of predators on a remote tropical paradise. However, as little as 5mya, continental landmasses (including Europe, Africa and India) also had their own … Read More
Richard Bizley (UK) Life on Earth has been affected and shaped by geological and astronomical events during the 4.5 billion years since it was formed. Scientists study geological and palaeontological processes to answer some rather fundamental questions. What did the animals and plants look like and how did they interact? … Read More
Henk Oosterink (Netherlands) The Lower Muschelkalk (from the Anisian age of the Middle Triassic) of the quarry at Winterswijk in The Netherlands is well known for its beautiful and sometimes abundant finds of reptile footprints and bones. A few, almost complete, skeletons have even been found. Most of the bones … Read More
Paul D Taylor and Consuelo Sendino (UK) Last week, In the first par of this two part series (see Dinocochlea (Part 1): The mysterious spiral of Hastings) we introduced Dinocochlea ingens, a gigantic spiral fossil from the Lower Cretaceous Wadhurst Clay Formation of Hastings, Sussex. Discovered in 1921 during the … Read More
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
