Archaelogical dating

“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.

Buckland's immediate successors did a little better.

It will also outline where artifacts recovered from the project will be stored, and how the research will be reported and shared with the public.

This expository paper gives a survey of statistical problems arising in two important and widely used scientific methods of dating archaeological deposits, namely tree-ring-calibrated radiocarbon dates and seriation.

Radio carbon dating determines the age of ancient objects by means of measuring the amount of carbon-14 there is left in an object.

Relative dating stems from the idea that something is younger or older relative to something else.

In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.

In 1823, palaeontologist William Buckland painstakingly removed the fossils from a cave in Wales, and discovered ivory rods, shell beads and other ornaments in the vicinity.

He concluded that they belonged to a Roman-era witch or prostitute.

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.

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.

When it comes to dating archaeological samples, several timescale problems arise.
