Additional specimens showed probable human modifications.

The lower number than might initially be expected reflects the rigor of the analysis — the researchers excluded specimens where any reasonable doubt existed about the cause of the marks.

The 15 confidently identified specimens showed marks consistent with specific butchery activities: skinning marks on the extremities of limbs, where a person processing a carcass would have run a stone tool along the bone while removing the skin; defleshing marks on the shafts of major limb bones, where a stone tool would have been used to strip muscle from bone; tendon removal marks at specific anatomical locations where major tendons attach; and dismemberment marks at joint surfaces, where the carcass would have been divided into transportable portions.

The specific anatomical locations of the marks, and the specific activities they implied, told a story.
