The numbers of C14 atoms and non-radioactive carbon atoms remain approximately the same over time during the organism’s life.

If a piece of wood was already centuries old when it was burned, radiocarbon dates of the resulting charcoal would be centuries older than the mortar for which it was burned.The number of dates from the two projects was only large enough to allow for statistical comparisons for the pyramids of Djoser, Khufu, Khafre, and Menkaure. First, there are significant discrepancies between the 19 dates for Khufu and Khafre, but not for Djoser and Menkaure.Second, the 1995 dates vary widely even for a single monument.But material from the time of the pyramids lends itself well to radiocarbon dating because they fall into the 2575-1640 date range.
