Stephen K Donovan (The Netherlands) Building stones may tell us something or nothing about the geology of the local area. As Ted Nield (2014) recently highlighted in his book, Underlands, stones used in Britain today are rarely local. Once upon a time, local stone would have been derived from a… … Read More
Steven Wade Veatch (USA) Quartz (SiO2) is a common mineral found in all three classes of rocks (igneous, metamorphic and sedimentary), in many environments and in a range of colours. However, rose and blue quartz are less common than some of the other varieties. This article discussed these two extraordinary… … Read More
Trevor Devon (UK) Eleven members of the Hastings and District Geological Society (HDGS) assembled in front of the Canterbury Law Courts on a fine Sunday morning in June 2010 to meet up with our guide for the day, Geoff Downer. Geoff had previously given a talk to HDGS in the… … Read More
Bob Williams (UK) Chert and flint are crystalline (perhaps more accurately described as microcrystalline) forms of rock that man has made use of from Stone Age times. The crystals consist of a microcrystalline form of silica, more commonly known as quartz (silicon dioxide). Flint is the better-known form of this… … 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
Stephen K Donovan (The Netherlands) My late wife, Dr Trina MacGillivray, was a geomorphologist. She loved the Netherlands and the Dutch landscape, but more than once made astute comparisons with the scenery of other northern European countries. The Dutch landscape, if it has a fault, is too organised, too well… … Read More
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.
It won’t come as any surprise to a reader of this magazine, but might to the vast majority of the UK population (and probably anyone reading this elsewhere), but this country is a great place to find dinosaurs.
Growing up, I collected and purchased trilobite fossils for my own personal collection, to learn about and understand prehistoric life. They were to me, and still are, a fascinating group of fossils to examine and wonder about how the myriad of different forms evolved.
This fascinating book looks at the professional interaction over more than 30 years between a respected husband and wife team of US palaeontologists working for most of their professional lives in Australia (Prof Pat Vickers-Rich and Tom Rich) and a freelance artist (Peter Trusler), as he tries to interpret their work and bring to life ancient organisms and environments.
Normally, I wouldn’t be interested in semi-precious stones and other pretty things. Personally, I prefer grubbing around in the dirt, perhaps for those far more beautiful, elusive and perfectly formed Cretaceous terebratulids or Silurian trilobites. However, some semi-precious stones have the advantage of also providing a tangible link to the ancient history of life.
I like the GA guides. They are excellent resources for amateurs and professional geologists alike and I frequently browse mine, planning geological trips I will probably never take, because I live in geological unexciting London.
