Slickstones Quarry, Cromhall, Paleontological site in Cromhall, England.
Slickstones Quarry is a quarry with a large lake featuring rock formations from the Carboniferous period, approximately 350 million years old. The limestone and oolite layers expose sedimentary rocks that were once part of a shallow marine environment, now revealing fossils of ancient creatures preserved within the stone.
The quarry was officially designated as a protected scientific site in 1966 due to its geological and paleontological importance to researchers. This recognition ensured the preservation of its rock layers and fossil deposits, allowing continued study of the ancient life forms they contain.
The site draws scientists and geology enthusiasts who recognize its importance as a window into prehistoric life and the evolution of species over millions of years. Visitors who explore the exposed rock layers can see firsthand how different organisms inhabited this region long ago.
The site is actively used for diving instruction and water safety training, which means access to certain areas may be restricted or controlled. Visitors should check conditions beforehand to understand which parts of the quarry are open for viewing and where activities take place.
Among the numerous fossils found here is Agnosphitys cromhallensis, a small early reptile about 2 feet long that fed on insects. This creature ranks among the earliest known members of its lineage and demonstrates the variety of life that existed during this ancient period.
