Fossils, geology and minerals. Highly acclaimed international earth science blog with over 900 articles and book reviews.
At first glance, Geology: an illustrated history appears to be another entry in the now familiar genre of large-format, image-rich popular science books. In practice, however, David Bainbridge has produced something rather more distinctive: a visually driven history of geology in which images – maps, diagrams and artefacts – take a leading role, with the text providing interpretation and context.
Steve Snowball (UK) This article is a response to a request by the editor of Deposits to write about my inspiration and reasons for writing a series of fossil collecting guides, the latest of which is A Field Guide to Collecting British Cenozoic Fossils, by myself and Alister Cruickshanks, and … Read More

Jon Trevelyan (UK) This is the eleventh and last of my series of short articles on fossils of the Ediacaran Period. Yorgia is one of the most distinctive members of the Ediacaran biota – a broad, quilted, segmented organism that thrived on the shallow seafloors of the White Sea region … Read More
Jon Trevelyan (UK) Britain is often described as geologically quiet. There are no active volcanoes, no subduction zones, and only modest earthquakes. Yet, for its size, few countries display such a concentration of geological variety. Mountain uplands, volcanic terrains, deeply folded rocks, and ancient metamorphic cores all occur within a … Read More
Jon Trevelyan (UK) This is the tenth of my series of short articles on fossils of the Ediacaran Period. Of all the organisms populating the Ediacaran oceans, Tribrachidium stands out as one of the most geometrically extraordinary. Living around 555 million years ago, it possessed a perfectly tri-radial body plan … Read More
Books devoted specifically to collecting Britain’s Cenozoic fossils are surprisingly rare. While collectors are well served by guides to the country’s Palaeozoic and Mesozoic fossils, the younger deposits that record the last 66 million years of Earth history have received far less attention. A Field Guide to Collecting British Cenozoic Fossils aims to address that gap by providing a practical introduction to the fossils and collecting sites associated with these deposits.
Jon Trevelyan (UK) The geology and palaeontology section at the Museo di Storia Naturale: geology and palaeontology in Verona is one of those museum experiences that perhaps quietly insists you pay attention if you notice it there among the other attractions of this lovely town. It doesn’t shout with flashy … Read More
Jon Trevelyan (UK) This is the ninth of my series of short articles on fossils of the Ediacaran Period.

Kimberella is one of the most influential fossils from the Ediacaran period, living around 555 million years ago and preserved primarily in the White Sea region of northwest Russia. Unlike the … Read More
The Oldest Rocks on Earth is composed in a consciously popular-science style, making it an enjoyable read, as well as an informative one for readers interested in how geologists reconstruct the earliest history of our planet. This approach allows Simon Lamb to interweave the science with his own research history, particularly his PhD work and later field studies in Swaziland (now renamed Eswatini), where he investigated some of the oldest rocks on Earth.
Jon Trevelyan (UK) For much of the twentieth century, generations of students (and amateurs like me) learned a tidy, mid-Cretaceous succession for southern England: Lower Greensand – Gault Clay – Upper Greensand – Chalk. It appeared in every textbook, diagram and museum panel. There was an appealing symmetry to the … Read More
Jon Trevelyan (UK) This is the sixth of my series of short articles on fossils of the Ediacaran Period. Funisia dorothea is one of the most revealing fossils from the late Ediacaran Period, offering a rare glimpse into the behaviour of early animals rather than only their anatomy. Found in … Read More

This final article turns to the continents, examining how the CPE transformed terrestrial landscapes … Read More
Jon Trevelyan (UK) This is the fourth of my series of short articles on fossils of the Ediacaran Period. And among the most intriguing organisms of the late Ediacaran Period is Ernietta, a sack-shaped, partly infaunal creature that lived around 548-541 million years ago in the shallow seas of what … Read More
At first glance, What Did Dinosaurs Think About? looks like a slightly mischievous title attached to a familiar subject. Dinosaurs, after all, have been thought about endlessly; whether they themselves did much thinking is another matter. Ronan Le Loeuff’s book makes no claim to settle that question definitively, but it does something arguably more interesting – it asks what sort of sensory world dinosaurs inhabited, and how that might have shaped their behaviour.
Stephen K Donovan (UK) If asked what is my favourite fossil collecting site, I would have to say the Farquhar’s Beach oyster bed on the south-central coast of Jamaica. I taught at the University of the West Indies for over 12 years and this locality was an easy drive. In … Read More
Jon Trevelyan (UK) This is the second of three articles on the Carnian Pluvial Event (CPE). The first covered the climate engine of the CPE. This article turns to the marine record, tracing how the CPE destabilised reefs and reorganised shallow-marine ecosystems. When the Triassic seas lost their balance In … Read More
Planetary geology occupies an awkward but fascinating position between disciplines. It draws its physical framework from physics and astronomy, its observational tools from remote sensing and space missions, and its interpretative instincts from terrestrial geology. Planetary Geology: An Introduction by Dominic Fortes and Claudio Vita-Finzi has, since its first appearance, sought to bring these strands together into a coherent teaching text.
Jon Trevelyan (UK) This is the third of my series of short articles on fossils of the Ediacaran Period.

Charniodiscus is one of the most characteristic frondose organisms of the Ediacaran Period, living around 560-555 million years ago in the quiet, low-energy seafloors that preceded the Cambrian explosion. With its … Read More
The Classic Geology in Europe series has, over many years, established a distinctive and reliable identity: authoritative regional syntheses written by specialists, designed for geologists who want to understand landscapes through field observation rather than armchair generalities. The Southern Pennines sits comfortably within that tradition and, in several respects, exemplifies the mature strengths of the series.
