“Carbon-14 dating has a margin of error of 100 years. In order to date Egyptian dynasties, we need to have specific dates; you cannot use carbon dating," Hawass explained to Al-Masry Al-Youm. "This technique shouldn’t be used at all in making changes to the chronology of the ancient Egypt, not even as a helpful addition.”
I recall this was his same reasoning when questioned why he would not allow dating of the graffiti, though I would not be surprised if RCD had not already been done on it and the result was not pleasant.
And actually RCD has an error rate of 100-400yrs depending on sample quality.
