Haven Cliff at Seaton is an actively eroding coastal site, where recent landslides have exposed fresh material from the Chalk and Upper Greensand. The foreshore and fallen blocks can yield a range of fossils, including echinoids, ammonites and bivalves, particularly after storms and at low tide. With regular cliff falls supplying new material, it can be a productive location for collectors willing to search carefully.Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦

Seaton Hole, at the western end of Seaton Bay, exposes fossil-bearing Upper Greensand and Chalk beneath White Cliff. Oysters, other bivalves and echinoids are useful finds to recognise in naturally weathered loose material, with rarer ammonites also recorded. Red Triassic mudstones below the Cretaceous rocks reveal a much older chapter of the coast’s history. Visit only when the tide and beach conditions leave a safe route well clear of the unstable cliffs. Cretaceous, Cliffs and Foreshore, Rating: ♦♦♦
