Question

Quizplus · Accepted Answer

Tooth marks and stone-tool marks have distinct characteristics. Tooth marks typically leave smooth grooves along the surface of the bone, while stone-tool marks leave many parallel grooves. This is because teeth have a round cross-section, while stone tools have a flat edge that creates parallel grooves as it cuts into the bone.
