Archeoligy dating

Within 30,000 years, 98% of the already vanishingly small quantities of carbon-14 in bone is gone.And carbon-14 molecules from surrounding soil start to seep into the fossils.Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object.A man called Willard F Libby pioneered it at the University of Chicago in the 50's. This is now the most widely used method of age estimation in the field of archaeology.Collagen, the part of bone that contains the most carbon suitable for dating, sops up contaminants like a sponge, creating a false record.

“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.

That vision sometimes clashes with other scientists' views, but Higham makes no apologies for his interpretations as long as the dates are solid.
