Industrial revolution radiocarbon dating
Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws.
The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope.
Unlike many other radiometric dating methods, carbon dating has been calibrated for historical periods and within that range can give reliable results.
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.Despite this, however, caution is still necessary in accepting dates derived from carbon dating.
