Guide to minerals: Amazonite

Steven Marquez (USA) The specimen displayed is a variety of microcline feldspar, referred to as amazonite. Many jewellers love this mineral for making cabochons because of its brilliant colour, which is thought to be caused by traces of lead and water. The gemstone is called the “Stone of Hope”, because … Read More

Geological expedition along the southwest coast of Scotland

Dr Robert Sturm (Austria) Compared to the geological architecture of other European countries not exceeding a total area of 100,000km², the geology of Scotland is characterised by an unusual diversity of geological features. Due to its tectono-metamorphic complexity Scotland attracted numerous earth scientists in the eighteenth and nineteenth centuries, whose … Read More

Guide to minerals: Amethyst

Steven Marquez (USA) Amethyst is the violet to purple variety of quartz. It is often associated with albite and orthoclase in pegmatites. Fine specimens of amethyst can be classified as semiprecious gemstones. This specimen was found in Cripple Creek Colorado, as a near surface deposit on the David Leighton gold … Read More

Geology and fossils of the Spilsby Sandstone Formation of Nettleton, Lincolnshire

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).

Iguanodon is older than you think: The public and private announcements of Gideon Mantell’s giant prehistoric herbivorous reptile

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

Book review: Walking the Jurassic Coast: Dorset and East Devon: The Walks, the rocks, the fossils, by Ronald Turnbull

There are a lot of guide books to the Jurassic Coast Work Heritage Site. This one is intended to provide a useful introduction to the general geology of the coastline, dealing with its formation, fossils and plate tectonics (among many other things), but specifically in the context of walks – for both afternoon rambles and long distance hikes for the more committed.

Book review: A History of Life in 100 Fossils, by Paul D Taylor and Aaron O’Dea

I wouldn’t say I know Paul Taylor, but I did once go on a fieldtrip with him, organised by the Natural History Museum (NHM) in London, more years ago than I care to remember. It was to the Coralline Crag of Suffolk, which was chock full of bryozoans – Paul’s favourite niche fossil. And very interesting it was too – as was Paul. Therefore, I am not surprised how fascinating this book turns out to be.

Book review: Introducing Mineralogy, by John Mason

I have been fortunate enough to review for this magazine a large number of books from the Dunedin series of guides introducing aspects of the different sciences, especially the earth sciences. And Introducing Mineralogy continues the high standard set by its predecessors. It is slightly larger than some of the other guides in the series, but is still beautifully illustrated, nicely written and very informative.

Book review: Geology and Fossils of the Hastings Area (2nd edition), by Ken Brooks

I remember buying the first edition of Ken Brook’s fascinating little guide on Hastings a long time ago, and bumbling off to Hastings in the hope of finding Lower Cretaceous dinosaurs and tree ferns. Sadly, I was disappointed, as the area is not as productive as, say, the Dorset or North Yorkshire coastlines. Having said that, I have been back a few times armed with that first edition and have enjoyed the visits every time.

Book review: Early Miocene Paleobiology in Patagonia: High-Latitude Paleocommunities of the Santa Cruz Formation, by Sergio F Vizcaino, Richard F Kay and M Susan Bargo

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.

Book review: The Artists and The Scientists Bringing History to Life, by Peter Trusler, Patricia Vickers-Rich and Thomas H Rich

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.

Book review: Guides to: Fossils & Rocks of the Jurassic / The Geology of the Lake District – an introduction / The Geology of Cornwall – an introduction, by Robert Westwood

These three guides by Robert Westwood are in the same simple format. All are local geological guides to specific areas of the UK and all are illustrated by lovely full colour photographs. They all contain simple, introductory geological introductions for the uninitiated, and then more detailed expositions of what makes the regions so special.

Book review: Amber: Tears of the Gods, by Neil D L Clark

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.

Book review: The Tunguska Mystery, by Vladimir Rubtsov and Edward Ashpol

It appears that I was naive to assume the Tunguska explosion of 1908 had been adequately explained. It was a meteorite or, more probably, a comet that exploded above a remote area of Siberia. Wrong! This fascinating book shows that we still await an adequate scientific explanation and the jury is still out on what precisely the object was.
