Holwell Quarries, Geological Site of Special Scientific Interest in Somerset, England
The 1.3-hectare Holwell Quarries features various rock formations, including Carboniferous Limestone with vertical fissures filled with Triassic and Jurassic sediments.
Geologist Charles Moore discovered teeth of Haramiya in 1867 within Neptunian dykes, marking an important advancement in the study of early mammals.
The quarries contribute substantially to geological education, providing researchers and students with access to rock formations spanning multiple geological periods.
Visitors can observe quarry operations from a designated viewing platform at the northernmost pit, while following safety guidelines established by site management.
The Rhaetic fissure fillings contain eight genera of reptiles, including the first British record of Placodont and specimens of Thecodontosaurus and Palaeosaurus.
