A prehistoric tool made from elephant bone has been discovered in Europe, with reports suggesting it may be around 480,000 to 500,000 years old. The tool is believed to be the oldest known elephant bone tool found in Europe, with some outlets describing it as a hammer or ax sharpener. The discovery was made in England, specifically at a site known as Boxgrove, and is seen as a significant find in the study of early human tool-making skills.
