Toby,
Here's something you might consider as you evaluate the radiocarbon dates you cite:

Manning et al, Fluctuating radiocarbon offsets observed in the southern Levant and implications for archaeological chronology debates. PNAS May 29, 2018. 201719420; published ahead of print May 29, 2018. https://doi.org/10.1073/pnas.1719420115

What Sturt Manning has found is that radiocarbon dates for organic materials from the Levant differ by as much as 60% at the 95% confidence level from organic materials collected from Northern Europe. He concludes that the Northern European calibration dataset must be a function of the local environment/climate and so can be applied to dating organic material from the Levant only if some unknown calibration factor is applied to compensate for the climatological differences between the two geographical regions. That for him is an "unknown unknown" that can influence dates by as much as "several decades."

My advice FWIW is to avoid becoming dogmatic about what we think we know. Make assumptions explicit so they can be more easily corrected when new evidence comes to light. That keeps us honest.

    Greetings, In the Jericho section of Wiki's page on Dr Bryant Wood, it argues against Wood's dating based on Radio Carbon dating which it refers to 8 times. It however totally leaves out, IMO, Wood's ... more
