If after more extensive exploration, and particularly if they find the city attached to the cemetary, it will be interesting to determine if in fact there was a major decline in this community after 2,000 BC. Ever since blam posted the info about the 4,000 year old 2 mile diameter boloid crater in the Iraq Marshes, I have been looking for other signs of significant disruption of civilization in the Mediterranean and Middle Eastern world of that epoch.
Depends on how the dating of the site was done — the earlier strata may not be that old.
