In learning more about old wood, I learned that this problem occurs for marine archaeologist too.If a stump from old wood is found underwater at a shipwreck for example then the archaeologist need to be aware and not use this misleading data.

To check on the method before applying it on various historical and paleontological material, Libby chose material of Egyptian archaeology, under the assumption that no other historical material from over 2,000 years ago is so secure as to its absolute dating.

Therefore the claim was made that the magnetosphere around the earth, discovered in 1958, suffered occasional weakening, thus allowing more cosmic rays to pass it and to hit the nitrogen atoms in the upper atmosphere, changing them to radiocarbon.

It was further claimed that the magnetic field of the earth might have reversed its polarity in the last 40 thousand years, a phenomenon known to have happened in geological epochs.

These items will also bring in new radiocarbon to the bone.

Both of these contaminates, natural and artificial, will make the bones carbon dating much younger than it actually is.
