On the Iron age in TN. There is skepticism about the dates but a lot of the skepticism is fuelled by racism and political needs and such. Some skepticism needs to be there except I think we need larger collaboration to answer that convincingly. I am a believer in the dates. I think it's quite likely, but there needs to be some kind of larger, international collaboration perhaps with archaeologists from other places invited to verify the findings and perhaps lead further excavations.
