Bracklesham Bay’s Eocene sands and clays yield shells, shark and ray remains when low tide and scour expose the beds. The guide centres on Bracklesham Lane and the nearby Earnley fossil horizons. The broader four-formation Bracklesham Group succession is spread along the bay, rather than exposed together by the car park. Eocene, Foreshore, Rating: ♦♦♦♦♦
The shore from Holywell towards Cow Gap exposes fossiliferous Cretaceous chalk and an important Cenomanian–Turonian boundary section. Ammonites, bivalves and brachiopods occur in the rocks, but fossils in loose blocks may have fallen from higher beds. Tides, slippery ground and unstable cliffs make careful planning essential. Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦♦♦
The Seven Sisters cliffs east of Cuckmere Haven expose flinty Late Cretaceous chalk, with echinoids, shells and other fossils in loose material. Distinctive flint bands trace the bedding through the high brows. This guide follows the east-bank coast; Seaford Head across the river is a separate locality. Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦♦
The shore from Pett Level and Cliff End towards Fairlight Cove records Early Cretaceous rivers and muddy environments. Its Cliff End Bone Bed is important for fish, reptile and rare mammal remains. Fossils may occur in loose material, but unstable cliffs, soft ground and rapid tidal cut-off demand particular care. Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦
Aldwick and Bognor Rocks expose early Eocene London Clay when beach conditions permit. Shells, plant remains and fish-bearing nodules and pyritic debris make this an important fossil coast, also known for rare insects. The wider scientific section extends towards Pagham, with different reefs exposed in different places. Eocene, Foreshore, Rating: ♦♦♦♦
Seaford Head’s chalk foreshore is noted for echinoids, especially in the beds around Hope Gap, although many specimens are worn or incomplete. Its flints, marls and hardgrounds record a changing Late Cretaceous succession along the coast. Hope Gap steps are closed: the geological account is not a route to the shore.
