The Clactonian is named after finds made at Clacton-on-Sea in the English county of Essex in 1911. The artefacts found there included flint chopping tools, flint flakes and the tip of a worked wooden shaft along with the remains of a giant elephant and hippopotamus. Further examples of the tools have been found at sites in Swanscombe, Kent, and Barnham in Suffolk; similar industries have been identified across Northern Europe.
