Wellacre Quarry
Wellacre Quarry is a 12.3 hectare geological Site of Special Scientific Interest in Gloucestershire, notified in 1974. It is within the Cotswold Area of Outstanding Natural Beauty and the site was formerly known as Blockley Station Brickworks. The site is listed in the 'Cotswold District' Local Plan 2001-2011 as a Key Wildlife Site and a Regionally Important Geological Site.
Geology
The site is stated as providing the best exposures in Britain of part of the Lower Jurassic, Middle Lias rock succession. This is the subdivision called Luridum Subzone. In other places in Britain this subzone is thin and incomplete, but at Wellacre Quarry it is thick, richly fossiliferous, and there is full research documentation available.The strata contain an abundant fossil fauna. This includes an important suite of ammonites.
Specimens from this site have been the subject of research and have provided insight into the evolution and shape of ammonites.
