Summary

Microscopy and 3D scans identified a nearly 500,000-year-old Boxgrove bone fragment as a repeatedly used retoucher.

Flint fragments embedded in impact marks show that early humans used the dense elephant or mammoth bone to repair handaxes. The Science Advances analysis makes it the oldest known elephant-bone tool in Europe, though the species and whether people hunted or scavenged the animal remain unknown.
