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.
Jon Trevelyan (UK) This is the first of my series of short articles on fossils of the Ediacaran Period.

Stephen K Donovan (UK) The south of England in the late 1940s and 1950s must have been a wonderland for the field palaeontologist. There were still many working or recently discarded quarries. Transport was easy and affordable by rail and bus. Visits to quarries were rarely difficult. It was a … Read More
At first glance, the title might mislead you into expecting a simple guide to finding fossils while strolling along the beach – a sort of field companion for holiday rock-hunters. But Stephen Donovan’s Fossils on the Seashore is a very different creature. It’s not about collecting curiosities for the mantelpiece. It’s about understanding the dynamic relationship between the living and the fossil record, and how coastlines act as natural laboratories for palaeontological and neoichnological study
There are few books (and indeed writers) that have managed to bring fossils, fieldwork anecdotes, scientific rigour and humour together as effortlessly as The Secret Lives of Dinosaurs, Dean R Lomax’s newest offering (with art word by Bob Nicholls). It is more than just a compendium of strange fossils – it’s an invitation to look behind the display cases, to the lives of creatures long vanished (and not just dinosaurs as the title suggests).
Have you ever wished to time-travel to the Miocene while armed with a PhD and a GPS unit? Well, At the Foot of the Himalayas is your next best thing. This sweeping but masterfully integrated volume brings the Siwalik Hills – the sediment-rich, fossil-packed foothills of the Himalayas – into sharp scientific focus.
