The caribou pelvis — the other major dated specimen from the 2017 study — also tells a specific anatomical story.

The pelvis is associated with major muscle groups of the hindquarters — some of the most meat-rich areas of a large animal — and with the tendons that connect those muscles to the axial skeleton.

Cut marks on the caribou pelvis in specific locations are consistent with defleshing — the stripping of muscle from the bone surface — and with dismemberment — the separation of the hindquarters from the rest of the carcass at the sacro-iliac joint.

These are not random marks.
