Zachary Sepulveda (USA) Perched upon a grassy hill ancient hunters prepare to make a kill… Blaring trumpets shatter the airTerrified voices echo despairHurtling towards their own demiseA chance at life, their fate denies. The blood of giants spills upon the grassBrought forth by razor-edged volcanic glassMarching closer to defeat with … Read More
Gavin Noller (USA) I am currently studying an arrow straightening tool left behind by the Ute Indians of the Northern Colorado Plateau long ago. The artefact is made of an unusual material – a Jurassic dinosaur bone. As I work with this object (which is more than 13 decades old), … Read More
Zachary J Sepulveda (USA) and Steven Wade Veatch (USA) The Florissant Fossil Beds National Monument is known worldwide for its late Eocene (34Ma) fossil plants and insects. Recently, a fossil spider was discovered at the commercial quarry, which is near the fossil beds (Fig. 1). Due to the condition of … Read More
James Cresswell (UK) Eighty percent of Greenland is covered by ice and, in places, this is up to 3.4km thick. So, Greenland might not immediately spring to mind as a place to go to observe rocks. However, it is a huge country and the ice-free area, at 410,000km2, is nearly … Read More
Chetan Patel (USA) Often referred to as the Red Rock Country, the state of Utah boasts some of the most breathtaking landscapes formed from years of erosional artistry. Dominating this impressive landscape is the Colorado Plateau that spans the four states of Colorado, New Mexico, Arizona and Utah. Adjacent to … Read More
Nebraska has an excellent geology record, which is celebrated by some fine mosaics at the Nebraska State Capitol. When the building was being constructed, and at the request of Prof Hartley Burr Alexander of the University of Nebraska Philosophy Department and from drawings by his colleague Dr Erwin H Barbour (former director of the University of Nebraska State Museum), the artist, Hildreth Meière, was asked to create a series of mosaics.
Phil Stone (UK) Plate tectonics have produced some surprising juxtapositions, as the earth’s continental fragments have drifted and jostled over the eons. Microplates seem to have enjoyed most freedom of movement and none more so than that supporting the Falkland Islands. Though this archipelago is situated in the south-west corner … Read More
Stephen K Donovan (The Netherlands) The writers of holiday brochures invariably fail to mention, let alone emphasise, the bad points of a location. For example, I’ve lived in both Jamaica and the Netherlands, and, for me, the thing that unites these two countries is the number of mosquitoes. However, as … Read More
James Smith (USA) Author of the Declaration of Independence, creator of the University of Virginia, a Founding Father and third president of the USA, Thomas Jefferson was a pioneer. Of this, you are undoubtedly aware. And, like most pioneers, Jefferson fostered an interest in virtually every aspect of science. This … Read More
Stephen K Donovan (The Netherlands) and Joe SH Collins (UK) Decapod crustaceans (crabs) are among the most attractive of fossils. Yet, the beautifully preserved specimens seen in museum displays and dealers’ catalogues are in stark contrast with the usual haul of the collector, that is, scraps, commonly claws or (more … Read More
Kris Howe (USA) When you think of Texas, what comes to mind? It may be wide open spaces, longhorn cattle, cowboys and ten gallon hats. Now, there’s something else to add to the list – the oldest, definitive bird fossil in North America. That bird is Flexomornis howei, from the … 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
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
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
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
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
Graham Roberts (UK) There is an old maxim in the mining industry that says, “Mines are where you find them”. To put it another way, you cannot change the location of geological deposits. This is frequently unfortunate for all involved and, almost inevitably, takes exploration and mining companies to wherever … 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 Steve Koppes (USA) Hikers visiting the Kilauea Iki crater in Hawaii today walk along a mostly flat surface of sparsely vegetated basalt. It looks like parking lot asphalt, but, in November and December 1959, it emitted the orange glow of newly erupted lava. Now, a precision analysis of lava … Read More
Landis Wofford (USA) Like all mountains, the Blue Ridge Mountains of western North Carolina and Eastern Tennessee are the result of the action of plate tectonics. The crust of our planet is composed of five primary plates, or huge pieces of rock that move very slowly over deeper layers of … 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
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
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
Stephen K Donovan (The Netherlands) The two most significant geologists to visit Jamaica and study its geology between the two World Wars were both British: Charles Alfred Matley (1866-1947) and Charles Taylor Trechmann (1885-1964). Both had active research programmes in Jamaica and the Antilles in the 1920s and 1930s, mainly … Read More
Patagonia has not always been the cold, arid and dry place it is today. About 17mya – because the Andes were much lower allowing humid winds from the west to reach the area – it consisted of substantial forests and grasslands. It was also inhabited by strange and wonderful animals, many of which are now extinct, such as glyptodonts, huge snakes and the giant, tapir-like astrapotheres.
Any serious collector of fossils will certainly have heard of the famous Green River, Morrison and Hell Creek formations. These, however, are not commonly detailed in guides that can easily be obtained in the UK.
