Reighton Gap

Reighton Gap is a useful stop along the Yorkshire coast, offering a mix of Kimmeridge Clay fossils and glacial erratics. When exposed, the clay can yield ammonites and marine shells, although productive layers are often covered and depend on scouring tides. The overlying boulder clay is particularly interesting, producing erratic fossils from Jurassic, Cretaceous and even Carboniferous rocks, giving a wide variety of finds in one location.Jurassic, Erratics (Jurassic, Cretaceous, Carboniferous), Cliffs and Foreshore, Rating: ♦♦♦

Corton

Ammonites, belemnites and reptile remains can all be found in the boulder clay, along with many erratic rocks full of shells. The foreshore sometimes yields fossil wood, seeds and bone from the Forest Bed during times of scouring. This used to be a highly productive site, but the sea defence limits scouring.Pleistocene, Erratics (Jurassic, Cretaceous), Cliffs and Foreshore, Rating: ♦♦♦

Grafham Water

Grafham Water was formally a shallow valley, now turned into a large lake, with water sports and a nature reserve. Today, plentiful fossils can be found along the banks of the lake and, during summer months when the water level is at its lowest, ammonites, belemnites and much, much more can be collected.
