Essex is well known for its fossil hunting opportunities, particularly from the Eocene London Clay, which is exposed along foreshore areas and coastal cliffs. These deposits are highly fossiliferous and yield a wide range of marine fossils.
Walton-on-the-Naze is the most popular location, with excellent exposures of both London Clay and the Red Crag Formation of Pliocene age. Fossils commonly found include shark teeth, which can also be collected at other sites across the county.
Additional locations such as Maylandsea offer more unusual finds, including fossil lobsters, while many Essex sites are located along river banks, providing varied collecting environments.
Walton-on-the-Naze combines early Eocene teeth, wood and rare vertebrate remains with the abundant marine shells of the much younger Red Crag. Tides and erosion continually change the beach, making some visits far more productive than others. Search loose material with care, keep away from the unstable cliffs and plan around the restricted tidal access. Pliocene, Eocene, Cliffs and Foreshore, Rating: ♦♦♦♦♦
Butts Cliff on the River Crouch is known for small early Eocene shark and fish remains weathered from the London Clay. Crabs and exceptional bird fossils add to its scientific importance. Search permitted loose material carefully, keeping well clear of soft estuary mud and unstable banks and using the signed riverside route. Eocene, Cliffs and Foreshore, Rating: ♦♦♦♦
Maylandsea’s low banks and foreshore yield London Clay lobsters and small fish remains, often among naturally weathered nodules and shingle. The site records an early Eocene marine environment, while shifting modern silt controls what can be seen. Deep tidal mud makes careful route choice essential.

The tidal foreshore at Harwich exposes the Harwich Stone Band, a hard, ash-bearing horizon formed in an early Eocene sea. Loose beach material can yield shark and fish teeth, fossil wood and seeds. The most useful patches change as waves move the shingle and sand, so careful searching matters more than covering a large area. Eocene, Foreshore, Rating: ♦♦♦♦
East Mersea preserves ancient river channels and their fossil wildlife beside the tidal shore at Cudmore Grove. Early Eocene London Clay underlies much younger deposits containing shells, wood and mammal remains. The Middle Pleistocene channel at Cudmore Grove is distinct from younger hippopotamus-bearing deposits farther west, and both need careful protection.

Steeple Bay exposes a London Clay foreshore with fossil lobsters, crabs, teeth and crinoid fragments. Finds are often small and are best sought among permitted loose material when tidal silt has cleared. The early Eocene marine fossils must be distinguished from much younger marsh deposits and archaeological material. Eocene, Cliffs and Foreshore, Rating: ♦♦♦♦
Wrabness offers early Eocene fossils along the tidal shore of the River Stour. Teeth, fossil wood and small fruits or seeds can occur among weathered beach material, while the cliffs reveal volcanic ash layers in the Harwich Formation beneath the lowest London Clay. Beach cover changes with the tides, and soft mud and unstable cliffs require care. Pliocene, Eocene, Cliffs and Foreshore, Rating: ♦♦♦
Stansgate’s tidal shore contains a fossil-bearing London Clay platform, often partly hidden by modern silt. Lobsters, crinoid stems, molluscs and occasional teeth record an early Eocene sea. This quieter locality needs patient searching and a safe route around the estuary mud, with access kept separate from working farm and sailing-club land. Eocene, Foreshore, Rating: ♦♦♦
