The deliberate choice of bone — and specifically the dense cortical bone of a mastodon — reflects a specific technological tradition and a specific understanding of material properties that is distinct from the Clovis stone-tool tradition.

The reconstructed tip, made from mastodon bone and shaped to a functional weapon geometry, is not the kind of object that exists by accident.

It is the product of knowledge, intention, and skill.

Someone made it.

Someone chose the mastodon bone as their raw material.

Someone worked it to the specific shape that the reconstruction revealed.

And then someone used it — delivered it against a living mastodon with enough force to drive its tip through the outer wall of a rib and shatter the bone inside the bone.
