Fabulous fossils in the Chedworth area

OUGS field trip, 2 July 2017

‘The old people are coming!’ A cohort of urchins, busily engaged in childish activities in Stony Furlong Quarry, thus greeted the arrival of the OUGS Severnside branch’s finest as we began a study tour in the Chedworth area.

Dr Paul Olver led this sortie into the Middle Jurassic, taking in two sections of railway cutting of the Midland & South Western Junction Railway to follow the succession of outcrops from the Great Oolite series in the quarry, dating from around 165 million years ago, to the older exposures near the Roman Villa.

First on the agenda was a cup of tea and the chance for breakfast at the Denfurlong Farm Shop – well worth remembering for future visits to the area. Then it was off to the cutting for a spot of hands-on geology, with fossils aplenty to be found in the rocks.

The White Limestone in the quarry proved a rich hunting ground whilst providing evidence of a marine environment, with the lower (softer and browner) rocks showing a more brackish environment with less biodiversity.

The fossil finds ranged from brachiopods and echinoids, plus one beautiful fish vertebra, to gastropods and bivalves. My personal favourite was a tiny but very lovely gastropod revealed in a crumbly piece of limestone I was able to pull apart, showing the creature and the impression on the opposite piece of stone.

From there we abandoned the urchins to their foraging and departed en masse on a picturesque drive to the car park by the Roman Villa. Lunch was a very civilised affair in the café at the National Trust property, before the party headed up into the woods and the second stretch of cutting.

This section of older rock dated from the Inferior Oolite Group (inferior only in the sense of lying beneath the Great Oolite Group), with echinoid fragments being the main attraction at our first stop, the Clypeus Grit.

Over the afternoon the group walked the length of the cutting, stopping at 10 locations to look for fossils and examine features including a tufa waterfall and a normal fault.

For me, as a relative newcomer to geology in the field, this was a great opportunity to see geologists in action and to have a range of people to chat to and question. The leisurely pace gave everyone the chance to have a good go at finding fossils – pick of the bunch were the fish vertebra, a beautiful bivalve like a razor shell, thalassinoides and Trigonia costata, shaped like a tricorn hat and featuring three sides with varying ornamentation – and to ask questions.

Best of all was just being able to chat to other members of the group about OU studies, geological activities around the area and field trips to far-flung areas of the globe.

Thanks to Paul for leading an excellent outing, and to the branch for putting on such a day trip. I’ve now acquired my latest piece of kit, a geological hammer, so I’m all set for the next one.

RARE Spiroceras bifurcati Fossil Heteromorph Ammonite Jurassic Coast Dorset UK COA

This listing features a VERY RARE fossil specimen of the heteromorph ammonite Spiroceras bifurcati, discovered by our expert field team, Alister and Alison, on 30 April 2025 at Burton Bradstock, along the internationally recognised Jurassic Coast, Dorset, UK.

The fossil originates from the Inferior Oolite Formation, part of the Bajocian Stage of the Middle Jurassic (~170 million years ago).

This unique morphology makes it an exceptional and highly sought-after specimen.

Scientific and geological context:

Order: Ammonitida

Superfamily: Stephanoceratoidea

Family: Possibly Tulitidae (classification debated)

Genus & Species: Spiroceras bifurcati

Morphology Features: Bifurcating ribbing, heteromorphic shell with open, loosely coiled whorls

Geological Stage: Bajocian

Depositional Environment: Shallow marine shelf with oolitic sedimentation typical of the Inferior Oolite
