A tectonic history of Britain (Part 1): Britain assembled – oceans, collisions and the making of a geological patchwork

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 relatively small area. The explanation for this diversity lies not in Britain’s present tectonic setting, but in a long and complex tectonic history that assembled the country piece by piece from fragments that originated far apart.

Book review: A Field Guide to Collecting British Cenozoic Fossils, by Steve Snowball and Alister Cruickshanks

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.

The death of the Upper Greensand: A stratigraphic obituary for a vanished formation

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 sequence, with two sands bracketing the impervious Gault and the Chalk resting neatly above. It seemed so natural that few doubted it.

Volcanoes, monsoons and a flooded supercontinent (Part 1): The climate engine of the Carnian Pluvial Event

This is the first of three articles on the Carnian Pluvial Event (CPE), often referred to as an ‘event’, although increasingly recognised as a prolonged episode, as I will discuss) of the Triassic that seems to have grown in importance and interest, and only become more widely known in relatively recent times. In this article, I will introduce the topic, concentrating on what might be called the “climate engine” driving what was happening.

A pebble across Deep Time: From Staffordshire to Budleigh Salterton and back again

I found the pebble almost by accident, while staying with friends near Eccleshall in Staffordshire. We had taken their two dogs (the much missed Holly and Chutney) out for an afternoon walk – the kind of slow, stop-start loop where the dogs dictate the pace and the conversation meanders as much as the footpath. Along a muddy stretch of track, something smooth and rounded caught my eye: a faintly banded, reddish stone lying half-buried among the usual Midlands gravel and mud.

The weird and wonderful of the Ediacaran Period (Part 2): Charniodiscus – a frond in the quiet depths of the Ediacaran seas

Jon Trevelyan (UK) This is the second 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

Book review: The Southern Pennines, by John Collinson and Roy Rosen (Classic Geology in Europe 13)

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.

Book review: Fossils on the Seashore: Beachcombing and Palaeontology, by Stephen K Donovan

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

An early specimen of ‘AMMONITES Walcotii’ and Sowerby’s ‘Mineral Conchology’

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

Fossils of the West Somerset coast

Neale Monks (UK) The West Somerset coastline, between Blue Anchor and Lilstock, exposes an almost complete succession of strata from the latest Triassic well into the Early Jurassic (Fig. 1). Fossils are abundant throughout, mostly invertebrates such as ammonites, brachiopods and oysters, but also with vertebrate remains at certain horizons. … Read More

Book review: Geologists’ Association Guide No. 77 – Cumbria, compiled and edited by Richard Wrigley

In many ways, this updated guide is exactly what I want from a GA guide – extensive coverage, well written, and oodles of colourful photos and graphics. I liked and used the previous edition (GA No. 2), and it’s a shame that, for example, the Ordovician site of Stockdale Quarry has disappeared, but it – and no doubt other locations – has been replaced by, what I suspect, are just as good, if not better, sites.
