On August 7, 2013 Eudald Carbonell, one of the directors of excavation at the caves of Atapuerca, Spain, announced the discovery of a flint blade dating back 1.4 million years. The three centimeter (1.2 inch) blade—a portion of a carving knife— was found in the Elephant Chasm cave at Atapuerca near the northern city of Burgos.
