The Shroud of Turin, a linen cloth that tradition associates with the crucifixion and burial of Jesus, has undergone numerous scientific tests, the most notable of which is radiocarbon dating, in an attempt to determine the relic's authenticity. (wikipedia.org)
In 1988, scientists at three separate laboratories dated samples from the Shroud to a range of 1260-1390 AD, which coincides with the first certain appearance of the shroud in the 1350s and is much later than the burial of Jesus in 30 or 33 AD. (wikipedia.org)

Years passed, and the scientists eventually analyzed the sample, along with others. (smithsonianmag.com)
The idea is to use the same principles as traditional radiocarbon dating, but a much smaller sample of painting is necessary. (ibtimes.co.uk)
these are a sample and carbon dating. (byaonline.org)
Radioactive dating estimates the pressure within those rocks using radiocarbon dating, protium and, if you had a sample is on the appropriate prices. (byaonline.org)

There was no evidence of human life, and scientists wondered what it was that finally took the mammoths out . (mentalfloss.com)
Some did argue that, in a way that parallels evolution in the biological world, the technologies may have evolved in different areas and spread more locally, but with limited dating evidence, this idea was almost impossible to support or reject from the available information. (encyclopedia.com)
The evidence is omnipresent, scientists say. (eenews.net)
The new study presents two additional lines of evidence for the older date range. (wate.com)
The date would place human habitation in the Americas during the Last Glacial Maximum and at least 5,000 years earlier than widely accepted evidence has yet suggested. (tpr.org)

And crucially, if supposedly old radiocarbon sources tilted these age assignments this far from expectation, then how do we know they did not also nullify other radiocarbon "ages? (icr.org)
Such raw ages can be calibrated to give calendar dates. (wikidoc.org)
