Carbon dating calibration
This problem is especially severe in shellfish or anything that eats shellfish; it is not unusual for freshly-killed seals to be dated as several thousand years old.
...various plants have differing abilities to exclude significant proportions of the C-14 in their intake. The varying rates at which C-14 is excluded in plants also means that the apparent age of a living animal may be affected by an animal's diet.
However, as explained above, carbon dating is incapable of providing dates in the range of millions or billions of years, and many scientists turn to other forms of dating to derive such extremely long time periods.
Some also argue that carbon dating should only be used on samples that fall within the range over which it can measure.
Carbon dating, or carbon-14 dating, is a method for comparing the ages of organic materials such as bones or artifacts made from anything that once lived.
Unlike many other radiometric dating methods, carbon dating has been calibrated for historical periods and within that range can give reliable results.
This calibration curve adds additional assumptions to the process as well as additional opportunities for error.
The bottom line is that the history of Egypt and Israel may need to be rewritten.
Theories about the correct dates for events in the ancient world have been debated for centuries.
Adding to the debate was the announcement of a recent study last month in the Cornell Chronicle.
Sturt Manning, Professor of Classical Archaeology at Cornell University, and colleagues, recorded a series of carbon 14 dates in tree rings from southern Jordan near Petra that have sent tremors through the field of archaeology.
