The rib tells us that approximately 13,900 years ago, somewhere near what is now Sequim, Washington, a person — a fully human being, cognitively modern, technically skilled, part of a community that possessed the knowledge to shape mastodon bone into a functional weapon — directed that weapon at a mastodon’s flank.

The weapon struck a rib.

The tip broke off inside the bone.

The hunter’s name is lost.

The community is lost.

The specific story of that day is lost.

What remains is the rib, and the fragments, and the reconstruction that made the fragments visible as what they had always been: the broken tip of a carefully made weapon, driven into the body of the largest animal that walked the late Pleistocene Pacific Northwest, nearly fourteen thousand years before the words to describe the event were ever written.

The science extracted this story from those fragments.
