Holwell Quarries, Geological Site of Special Scientific Interest in Somerset, England
Holwell Quarries is a quarry in Somerset featuring Carboniferous Limestone with fissures filled by sediments from later geological periods. The roughly 1.3-hectare site contains several pits where these different rock layers are clearly visible.
A naturalist named Charles Moore discovered teeth of early mammals known as Haramiya in stone fissures in 1867. This discovery was an important moment in science and helped advance understanding of early mammal evolution.
The quarries attract geologists and students who come to study layers from different geological periods. This location plays an important role in teaching and understanding Earth's history.
A viewing platform at the northernmost pit allows visitors to safely observe the work and rock formations. It is important to follow the safety rules of the site and stay within designated areas.
The stone fissures contain fossils of eight different reptile species from the Rhaetic period, including the first known British record of a certain marine reptile. This collection makes it an exceptional location for paleontologists studying early reptiles.
