Brook Brick Pit

Brook Brick Pit is a geological site in Surrey that exposes clay formations from the Atherfield Clay sequence. The roughly 0.9-hectare location displays layered rock formations visible across its countryside setting.

The rock layers here formed during the Lower Cretaceous period, roughly 120 million years ago, when southern England transitioned from dry land to shallow seas. This sequence of deposits records major shifts in water levels over time.

Scientists and researchers study the site to understand the transformation of southern England from terrestrial to marine environments during prehistoric times.

This is private land with restricted public access and serves as a scientific reference area. Visitors should respect these limitations and plan accordingly if interested in the site.

The deposits contain numerous bivalve fossils that represent remains of ancient shelled creatures from these prehistoric seas. These preserved shells offer clues about the types of marine animals that once inhabited these waters.
