Could dates assigned by that method be vulnerable to faulty assumptions that render them invalid? The age assignment for certain Viking bones caused a decades-long controversy until the carbon-14 methodology used to date them was recently exposed for its flawed assumptions.A mass burial of 250 to 300 skeletons was discovered in the Derbyshire village of Repton, England, in the 1980s.This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.

Rogers said: "I was irritated and determined to prove Sue and Joe wrong."However, when he came to examine threads taken in 1978 - luckily from the same section as the 1988 sample - he found cotton in them.

He said: "The cotton fibres were fairly heavily coated with dye, suggesting they were changed to match the linen during a repair.

It seemed likely they were the remains of the Scandinavian Vikings of the Great Heathen Army who wintered in Repton over a millennium ago during 873–874.

Eyewitness accounts indisputably reported the army’s historical presence during the latter 800s, so many modern historians concluded that these mass-grave skeletons were those very Vikings.

"I concluded that area of the shroud was manipulated by someone with great skill. The worst possible sample for carbon dating was taken.

"It consisted of different materials than were used in the shroud itself, so the age we produced was inaccurate." In the video, made shortly before he died of cancer in March 2005, he said: "I came very close to proving the shroud was used to bury the historic Jesus."This latest evidence, to be broadcast in The Turin Shroud: New Evidence at 8pm on Sunday on the Discovery Channel, is the latest chapter in the shroud's history.

In general it is always better to date a properly identified single entity (such as a cereal grain or an identified bone) rather than a mixture of unidentified organic remains.

Common materials for radiocarbon dating are: The radiocarbon formed in the upper atmosphere is mostly in the form of carbon dioxide. Because the carbon present in a plant comes from the atmosphere in this way, the radio of radiocarbon to stable carbon in the plant is virtually the same as that in the atmosphere.

He came to his conclusion after re-examining a theory from two amateur scientists that he had earlier dismissed as being from "the lunatic fringe".
