Contamination and repeatability are also factors that have to be considered with carbon dating.
A tiny amount of carbon contamination will greatly skew test results, so sample preparation is critical.
The bodies of living things generally have concentrations of the isotope carbon-14, also known as radiocarbon, identical to concentrations in the atmosphere.Due to all these factors, it’s common for carbon dating results of a particular sample, or even a group of samples, to be rejected for the sole reason that they don’t align with the “expected” results.That’s not unusual in science, so far as it goes, but the relationship between assumptions and interpretations must be kept in mind. At worst, it can make carbon dating circular and self-confirming, though there are other means of dating that can reduce this risk.Likewise, different living things absorb or reject carbon-14 at different rates.Two plants that died at the same moment, but which naturally contained different levels of radiocarbon, could be dated to drastically different times.
