Description: Cliffs at West Runton Beach The dark layer at the cliff base is the West Runton Freshwater Bed. The West Runton Freshwater Bed was formed by mud deposited by a river that once used to flow here about 600,000 to 700,000 years ago, long before the onset of the Ice Ages. Its main outcrop lies to the east of West Runton Gap where it forms a dark bed of up to two metres in thickness at the cliff base. This layer is very rich in fossil remains of plants and trees, molluscs, fish, amphibians, birds and large and small mammals - the skeleton of an elephant (Mammuthus trogontherii) was discovered near here in December 1990. http://www.museums.norfolk.gov.uk/default.asp?Document=400.500.050x1
