Freya, without knowing the specifics of the method used to date this particular site, I totally agree that such dating based on prior presumptive context is too often problematic. The obvious culprit is the uncertainty introduced by one or more subsequent cultures that may have moves into a previous culture's infrastructure and made it their own after clearing out the artifacts left by that previous culture. The Crusaders endeavored to remove all evidence of pagan cultures. The Romans apparently attempted to clear out the evidence of a prior culture at Baalbek and perhaps at the "forts" at Mons Claudianus and other sites in the eastern mountain desert of Egypt. When we moved into Manhattan, we removed the presence of the indian culture. It's a recurring phenomenon throughout history.
Good point. Also, if the landscape hasn't undergone some major changes it also makes sense people re-settle on the same sites. A suitable location is still a suitable location. Human needs don't change all that much. Nice along a river perhaps. Many old cities show periods of abandonment and resettlement. And in between, if there are still remains, foundations, materials, why not re-use it?
Think it was in one of those videos posted here were it showed a wall with pre-Inca, Inca and Spanish masonry. (With those incredible polygonal stones at the bottom). Perfect example.
Over were I live we have a whole bunch of dolmen. In some archaeologists found human remains and now they're all considered graves. However before the refrigerator and/or when regular houses got cellars they would have been ideal for storing. Stays cool in summer and doesn't freezes in winter. In fact this is exactly how people used to store meat and grain and all perishable supplies. Even tools that weren't weather resistant. They made an underground shelter. A man-made cave.
So perhaps these dolmen were the first things people constructed when starting a settlement. Now it makes sense to spend all this labor and energy on this structure. It's like laying the cornerstone for a building. The first building for the new settlement. The communal refrigerator. Big party when it's finished and the start of a new village.
Who knows how many eons later and populations being replaced over and over, they get re-used as graves. Some, not all. Which would also explain why there are many that have no traces of human remains or have ever been used for burial. Or why some only have 'burial gifts' (leftover supplies) and no bodies.
Similar this article. "ruins of ancient temples" Because that's all the ancients build right? Tombs, palaces and temples. Everything either for ritual of glorification. Never for practical purposes. And the dolmen were all graves. And in France they build them right into the ocean. Because they're at most only 5000 years old. [sarcasm off] It's such a mess. Very little science and a whole lot of dogma.
