Shroud of turin carbon dating flaws

Even as stubborn as I can be when it comes to accepting “facts” when other people have told them to me, I must concede that when multiple independent tests have reached the same conclusion, it is almost always because they invariably have gotten the answers.It should be noted that the key word in the sentence above is “almost.” As part of the Shroud of Turin Research Project (STURP) three different laboratories in Zurich, Oxford, and Tucson performed independent carbon dating tests.See the most recent report by Garza Valdes re-printed on "bio- plastic coating" he found on Shroud fibers, in sufficient quantity to throw the date WAY off.This organic material would of course be younger than the linen itself and would not have been removed in pretreatment.The new tests have recently been performed, putting the shroud in the right time frame so that it could be authentic.

He proposed testing the scorch marks on the shroud for more accurate carbon dating.

Let's start by noting that an organism growing on, and feeding on, the linen threads exclusively will simply re-shuffle the available carbon with no effect on the radiocarbon content.

Hence the growth must incorporate carbon from an external source, and to produce an age shift like that postulated, that source must be the atmosphere, whether by photosynthesis or some other mechanism.

[Correction: reader Dan Porter from the website called to my attention that the original article incorrectly cited a 2005 paper published by Benford and Marino.

This article is compiled from a series of postings that appeared on the Shroud Newsgroup, alt.turin-shroud.

In it, Rodger Sparks, a carbon dating expert from New Zealand, and William Meacham, archaeologist and Shroud researcher from Hong Kong, debated some of the theories that have been proposed regarding possible inaccuracies in the 1988 carbon dating test results.
