I am reminded of a piece I read about a dig in either Central or South America. It was probably a thousand years old and archaeologists were baffled by something commonly found in the burial sites. A local fisherman was able to readily identify it as a spacer for making fishing nets with consistently sized openings. So much of what gets left behind only makes sense if you have knowledge of human behavior. It isn't necessarily readily inferable from the physical remains themselves.
