Microscopic analyses of 130 of those bone points revealed surface cracks and other damage caused by high-speed impacts, likely because these artifacts were used as arrowheads, Langley and her colleagues conclude June 12 in Science Advances. Notches and wear at the bottom of the bone points indicate that they were attached to thin shafts.
