Hi Jonny,

Many thanks for your detailed info on this subject; much appreciated, what l know about carbon dating could fit on the back of a stamp.
Would not the logs in the Bent pyramid be an ideal candidate, see image from following link, [isida-project.org]
Often described as cedar; though l have not come across any detailed reports on these logs. If some of these logs are the trunk of a young tree, is this not an ideal candidate to date, as we have the entire cross section of the tree: the tree rings should give the age of the tree when it was felled and allowing the carbon dating of the tree to be better defined.
