They are patterned, anatomically specific, functionally interpretable.

They tell a story of someone who knew exactly what they were doing — who understood the anatomy of the animal they were processing well enough to make efficient, targeted cuts at the locations that would accomplish specific butchery objectives.

This anatomical knowledge is itself evidence of an experienced hunting-and-processing tradition.

You do not learn to efficiently butcher a large animal without practice, without teaching, without the accumulated knowledge of a community that has been doing this for generations.

The people who made the marks on the Bluefish Caves specimens were not learning for the first time.
