The shell middens that accumulate along the coast document the locations of fishing and shellfish-gathering activities, but they say nothing about the languages spoken at those locations or the social structures of the communities that visited them.

The petroglyphs and pictographs carved or painted on rock faces document the existence of sophisticated symbolic traditions, but they do not come with explanatory captions.

Against this vast background of lost human experience, the Manis rib and the bone point inside it represent something almost miraculous in their specificity.

They document not just human presence, not just a cultural layer in a sediment profile, but a specific act: a person attacking an animal with a specific weapon at a specific location at a specific moment in time.

This level of specificity is extraordinarily rare in the pre-Clovis archaeological record, and it is rare precisely because the conditions that allowed this evidence to survive — a weapon tip lodged in bone, bone preserved by wet anaerobic sediment, sediment disturbed by a backhoe, disturbed material recognized by a trained archaeologist — are conditions that very rarely come together.
