“It is another sobering example of cocked-up dates,” says Higham, whose laboratory is leading a revolution in radiocarbon dating.By developing techniques that strip ancient samples of impurities, he and his team have established more accurate ages for the remains from dozens of archaeological sites.Relative dating methods do not tell archaeologists exactly how old things are, but only how old things are relative to each other.Archaeologists work on the principle that objects at the bottom of an undisturbed were put there before objects that are above them, so objects found in the lower levels of a site are usually older than objects found in higher levels.

“He did a good job of excavating, but he interpreted it totally wrong,” says Tom Higham, a 46-year-old archaeological scientist at the University of Oxford's Radiocarbon Accelerator Unit.But in the 1970s a new method that used a fancy piece of equipment known as an Accelerator Mass Spectrometer (AMS) was discovered.Radiocarbon tests that use AMS are a lot faster, more accurate, and can date even very tiny samples, even corn kernels!In addition to radiocarbon dating being expensive and sometimes inaccurate, it also takes time, and most labs have long wait lists.It can be a long time before archaeologists are able to get the results of their tests.
