For this reason, researchers prefer to use “short-life” samples, such as seeds, grain or olive pits. In many studies, particular radio-carbon dates are not considered valid because they do not match the majority of dated samples from the site in question.In other words the particular sample is either too late or too early No doubt the rejection of certain dates as “outliers” and their exclusion from the model may lead to different dates.The calibration curve is revised periodically as more data are continuously accumulated.But the absolute date after calibration depends on which calibration formula is used. This uncertainty ranges from 20 years (for high-precision dating) through intermediate values of 50–100 years, and in some cases up to 100–150 years. For interpreting the results, different statistical models are used by different researchers.

— Using the largest set of radiocarbon dates ever obtained from a single Maya site, a team of archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to ...

The differences in the various dates for the transition from Iron I to Iron IIa are too small to be helped much by radiocarbon dating.

Hopefully, as radiocarbon dating continues to develop, it will eventually be more useful in solving the problems of Iron Age chronology.

The results, depending on the calibration, can be quite different. Naturally, different statistical models for interpretation of the same data will produce different results. After processing the data with all these scientific tools, most archaeologists “improve” the given dates in accordance with broader archaeological and historical considerations.

For all these reasons, contrasting dates have been reached in the ongoing chronological debate concerning the Iron Age.
