A dinosaur track investigation
My “Fossil Grandpa” took me to visit this neat site when I was in Texas last summer (2013). We drove to a small rural community, where it seemed there wasn’t anything to find. However, my […]
Encountering desert deposits in Oman
Oman is a geologically fascinating country, where the bedrock beautifully exposes a one-billion-year history. I had the opportunity to explore this country in a group expedition, during which we pursued our own scientific studies from […]
A warming medieval climate supports a revolution in agriculture
In the light of our current worries about climate change and global warming, this is the first a series of articles for Deposits that will cover significant climate changes that have occurred in the geological […]
Sand
As long as I can remember, I have collected interesting bits of rock, looking at their shapes and colours, and wondering what they were. This was fine as long as I had a garden shed […]
Emeralds from the Hohe Tauern (Austria): a precious stone with a long history
The mineral, emerald, represents the green variety of the hexagonal silicate mineral beryl, which has the chemical formula Be3Al2Si6O18. Its colour may be interpreted as the result of the addition of vanadium and chromium ions […]
The geology of islands
Islands are attractive places to visit, not just for geologists. Nonetheless, for us, they provide three advantages that favour collecting and research in the Earth Sciences. One of the attractions of an island is its […]
The abundant yet understudied fossil record of ghost shrimps
“Ghost shrimp” usually refers to decapod crustacean species from the family Callianassidae and Ctenochelidae, although sometimes the term is also used for other crustacean groups, such as caprelloid amphipods or, mostly in aquarium trading, for […]
Nebraska, USA: wonderful fossils, natural history museums and public art depicting fossils
Nebraska is known by vertebrate palaeontologists as the place in North America where there is a very complete Cenozoic geologic record of mammalian evolution over the last thirty-five million years or so. All you have […]
Erratic rocks in fields and on beaches of the Isle of Wight
The Isle of Wight is a marvellous place for the geologist on holiday, but there must be a suspicion that it has all been done before. When I first visited the island in 1999, my […]
Khajuraho stone temples of India
Khajuraho, in the state of Madhya Pradesh in India, was the cultural capital of the Chandela rulers of the tenth century and, even today, is a place that pays homage to artistic talent. There was […]
The histology of a sauropod rib bone found in the Wessex formation, Hanover point, Isle of Wight.
In September 2015, I went to Compton Bay on the Isle of Wight to hunt for dinosaur bones. It was equinox tides all week, so an ideal time to get out on the furthest rocks […]
Twilight of the Mammoths
Perched upon a grassy hill ancient hunters prepare to make a kill… Blaring trumpets shatter the air Terrified voices echo despair Hurtling towards their own demise A chance at life, their fate denies. The blood […]
The geology and landscape of Levisham and Newtondale, Yorkshire: an overview
This article is about the geology and geomorphology of the Levisham Bottoms and Newtondale area of Yorkshire. This is an interesting strip of virtually level land, which forms a shelf at about 150m above sea […]
Features in the field: ignimbrites of the Yr Arddu syncline (Caradoc, Upper Ordovician)
In July 1979, I was one of more than 20 undergraduate students at the Department of Geology, University of Manchester, to undertake their final year mapping project in the Snowdonia National Park in North Wales. […]
Exploding star missing from formation of solar system
A new study, published by University of Chicago researchers challenges, the notion that the force of an exploding star forced the formation of the solar system. In this study, published online in Earth and Planetary […]
An unusual association of a Recent oyster and a slipper limpet
My young son and I both have a taste for oysters, and have a favourite restaurant in which we like to eat them. It is in the Spui district of Amsterdam, which is also an […]
A Ute arrow straightener made of Jurassic dinosaur bone
I am currently studying an arrow straightening tool left behind by the Ute Indians of the Northern Colorado Plateau long ago. The artefact is made of an unusual material – a Jurassic dinosaur bone. As […]
A short introduction to trilobites
Many people interested in palaeontology and collecting fossils have either found fragments of trilobites in the field or marvelled at fossil examples of these animals displayed in museums around the world. Although they are essential […]
A Florissant fossil spider discovery

The weird world of fossil worm cocoons
Fossil hunters occasionally chance upon small glossy red to amber-coloured, roughly circular objects on bedding planes, when they crack open shales that were deposited in ancient swamps and rivers. These curious fossils range from about […]
An alternative view on climate change
Before you start shouting at your magazine, don’t worry, you’re not going to read that I think climate change isn’t happening or that human beings aren’t contributing to it. However, I am going to try […]
A phenomenal fossil fern – forgotten for 40 years
On some occasions, it is the hard sweat and toil of palaeontologists labouring in the field at carefully planned excavation sites that yields the prize specimen on which careers are built. On other occasions, it […]
The graptolites of Abereiddy Bay
Graptolites are curious fossils that are common in Lower Palaeozoic rocks where other types of fossils are lacking. The word ‘graptolite’ comes from Greek words that mean ‘writing’ (graptos) and ‘stone’ (lithos), and refer to […]
