Bracklesham Group

The Bracklesham Group (formerly Bracklesham Beds), in geology, is a series of clays and marls, with sandy and lignitic beds, in the Middle Eocene of the Hampshire Basin and London Basins, England.

The type section of the Bracklesham Group is the sea cliffs at Whitecliff Bay on the Isle of Wight, and it is also well developed on the mainland. The Group gets its name from a section at Bracklesham in Sussex. The thickness of the deposit is around 120 m. Fossil mollusca are abundant, and fossil fish are to be found, as well as Palaeophis, a sea-snake, and Puppigerus, a sea turtle. Nummulites and other foraminifera also occur.
