These tools are named after Clacton-on-Sea in the English county of Essex. There, in 1911, archaeologists found Clactonian artifacts along with the remains of a giant elephant and hippopotamus. These artifacts included flint chopping tools, flint flakes, and the tip of a worked wooden shaft. Archaeologists have found other Clactonian tools at sites in Swanscombe, Kent, and Barnham in Suffolk. Evidence shows that early humans made this type of tool throughout Northern Europe.
