One of the world’s most valuable fossil beds has been rediscovered, having been forgotten during Victorian times. Fossils recovered near Christian Malford in Wiltshire caused a sensation when they were unearthed in 1840 because they were the first to include the flesh of Jurassic wildlife.

Phil Wilby, of the British Geological Survey, has now rediscovered the site and led the first dig there in more than 150 years. He hopes that freshly recovered fossils can help to explain why tens of thousands of animals died simultaneously in episodes repeated many times over about a million years.

Fossil hunters and academics flocked to the area in the 1840s and 1850s to dig out extraordinarily well-preserved specimens of fish and squid-like creatures. But despite its importance as an extremely rare source of fossilised soft tissues preserved along with hard bones and shells, the location of the site was lost.

None of the Victorians who visited the site, even leading researchers from universities and museums, recorded the precise place and, when digging ended, the location was forgotten.

ABSTRACT

The small village of Christian Malford, Wiltshire (UK) is known to palaeontologists the world over because of the chance discovery of an astonishing fossil bonanza in the mid-nineteenth century. Pits in the Jurassic Oxford Clay yielded thousands of specimens of exquisitely preserved ammonites, fish and crustaceans, but became most famous for squid-like cephalopods and belemnites (collectively termed coleoids) with fossilized soft-parts. The precise location of the find has remained obscure, until now, and a new attempt is underway to understand the ancient environment that triggered this unusual preservation.
