Fossils, geology and minerals. Highly acclaimed international earth science blog with over 850 articles and book reviews.
Paul Lyle begins GeoHibernica with a slightly mischievous acknowledgement: the book exists only because the author of GeoBritannica was unable to take on its Irish counterpart himself. It is a revealing admission, and one that immediately invites comparison between the two works. That comparison is instructive, although not always in the ways one might expect.
Mike Leeder’s Geology and the Pioneers of Earth Science is an ambitious and absorbing exploration of the intellectual and personal stories behind the transformation of geology in the twentieth century. Published in September 2024, the book positions itself as an account of how the discipline shifted from a largely descriptive, field-based science into the more synthetic, quantitative and planet-wide framework we now call “earth science”.
Dr Neil Clark (UK) The last place most people will associate with amber is Scotland. Yet, it is the place where some of the oldest inclusions (from the Carboniferous) in tree resin have been found. Amber is defined differently by different cultures. Its precise origin is unknown, but is fossilised … Read More
Steve Koppes (USA) When the solar system was born 4.5 billion years ago, davisite and grossmanite were soon there. These minerals were two of the first solids to form when an interstellar gas cloud collapsed to form the sun. Found in the Allende meteorite (Fig. 1), they now carry the … Read More
Deborah Painter (USA) Why is there a reef in a cavern under a hill in south-central Pennsylvania in the USA? My good friends Richard Hedges and David Hawk and I wanted to know the answer. We had seen various websites which describe an amazing commercial cave with one wall composed … Read More
In recent years, geology has evolved from being primarily concerned with rocks, minerals and the Earth’s physical structure, to integrating fields, such as climatology, meteorology, biology and more. This interdisciplinary approach has become essential for understanding complex Earth systems and this book is part of that trend – a discussion of Earth’s climate and the evolution of life, in the context of geology.
Tony Forsyth (Australia) Located over 1,100km west of Sydney in New South Wales, Australia is the city of Broken Hill (Fig. 1). Nicknamed Australia’s “silver city”, with a population of over 20,000 people, it is now a prosperous centre for mining, the arts, tourism and film production. However, my wife … Read More
Mike Viney (USA) Introduction The Front Range of the Colorado Rockies is not a place one would expect to find a residence designed in the style of a European castle. So, for me, it was a delightful surprise to learn about the existence of Cherokee Castle in Sedalia, Colorado (Fig. … Read More
Last week, I published a book review of The Trilobite Collector’s Guide, by Andy Secher, in which I suggested that it was a great choice for a Christmas present for those who like geology. I think the same could be said for this (but it’s not all geology). Once again, it has a coffee table book feel, but once again, it is much, much more.
Deborah Painter (USA) It’s all about time, rocks and living things. When humans make attempts to record the distant past, there will be gaps in our knowledge. Historians and archaeologists have the luxury of the written word and of the preservation of culture in the form of fences and aqueducts, … Read More
Ru D A Smith (Malaysia) A fascinating aspect of palaeontology is the history of early descriptions and the process of assigning and revising the scientific names of fossils. A recently discovered nineteenth century ammonite specimen discussed here provides a vivid illustration of the sometimes tortuous process and can be connected … Read More
Marta Pino Larrío (Spain) In July 2023, I travelled with fellow geologists to Băile Herculane, an ancient Romanian town in the Western Carpathians, situated between the Danube and the Serbian border. Our mission was to analyse the site for a new railway tunnel that will replace the existing one. Băile … Read More
Steven Wade Veatch (USA) Hidden among geological marvels at a mineral show was a cinnabar-bearing chalcedony breccia-specimen (Fig. 1). The term “breccia” refers to a rock composed of angular fragments, while “chalcedony” describes a type of cryptocrystalline quartz. Adding “cinnabar” specifies the presence of mercury sulphide, which creates a distinctive … Read More
Dr Ross Barnett and Simon Sylvester In Zoology, nothing is more exciting than the rediscovery of an animal previously thought long extinct. The coelacanth (Latimera chalumnae) and the ivory-bill woodpecker (Campephilus principalis) are two famous recent examples of ‘Lazarus’ taxa. Well-publicised rediscoveries like these promote the idea that refugia containing … Read More
Michael D Johnson It has now been 63 years since a huge iron meteorite impacted the Sikhote-Alin Mountains of the former USSR. Imagine what it must have been like on that cold morning of 12 February 1947 – the tremendous smoke trail, the thunderous crash and the roaring sound it … Read More
Deborah Painter (USA) The famed English explorer of the “New World”, Captain John Smith, led expeditions during the early 1600s to create charts and plan settlements along the east coast of the United States, from what is now Virginia to Maryland and, on a subsequent voyage, New England. Smith’s map … Read More
Dean Lomax (UK) Dr Dean Lomax is now well known from his books, television appearances and especially for his work on marine reptiles. However, before all this, he wrote this article for Issue 21 of Deposits. After returning from a long summer working in the USA at the Wyoming Dinosaur … Read More
Neale Monks (UK) Not many palaeontologists would go on a field trip to the Houses of Parliament in London, but if you do something similar in the state of Nebraska, you will be surprised to find a whole variety of prehistoric life, including dinosaurs (Fig. 1), ammonites and trilobites. The … Read More
Rosalind Jones On the Hebridean island of Mull, on a day just before 1850, when potato famine and clearances brought misery to the Highlands and Islands, a man (perhaps collecting shellfish to stave off starvation) ventured down into a wind-swept gully on the Ross of Mull. Known as Slochd an … Read More
John A Cooper (UK) The legacy of Gideon Mantell’s fossil collection, sold to the British Museum in 1833, would have been so much more significant to Brighton had he been successful in establishing a permanent Sussex scientific institute to house it. In his article, Gideon Mantel and the dinosaur relic, … Read More
Rob Hope (France) A break from work, and also from reading about the history of palaeontology, enabled me to get away for a while. And a chance visit to the south of England found me driving through the lovely Sussex town of Lewes. Held up by a red light, I … Read More
Steve Koppes (USA) Although he is an experimental physicist who discovered new elementary particles in the early 1950s and invented the high-resolution scanning ion microprobe, Riccardo Levi-Setti also is known in paleontological circles for co-discovering a giant trilobite subspecies and for his book, Trilobites. Decades ago, as a diversion, Levi-Setti … Read More
Flavia Faedo (UK) The Thiepval Memorial is situated four miles (almost 6.5km) north of the town of Albert, in northern France, and was built to commemorate British soldiers who have no known grave, yet died here during the Great War of 1914-1918. This memorial rises majestically from the woods and, … Read More
