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: ♦♦♦
