Wibbo, carbon 14 dating is one method used to estimate the age of samples. For decades, historians and paleontologists have often relied on radiocarbon dating to estimate the age of fossils. However, according to Time magazine, “those estimates, while valuable, are also known to be somewhat uncertain.” The magazine added that “carbon 14 levels in the air—and thus the amount ingested by organisms—are known to vary over time, and that can affect the results of carbon dating.” After comparing the results of a carbon-14 test with a uranium-thorium test, a group of geologists at the Lamont-Doherty Geological Laboratory in Palisades, New York, found that the “radiocarbon dates may be off by as much as 3,500 years—possibly enough to force a change in current thinking on such important questions as exactly when humans first reached the Americas.”
