As stated previously, carbon dating cannot be used on artifacts over about 50,000 years old.

But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.This restriction extends to animals that consume seafood in their diet.

“If you’re trying to look at archaeological sites at the order of 30,000 or 40,000 years ago, the ages may shift by only a few hundred years but that may be significant in putting them before or after changes in climate,” he says.

One thought on “reasons radiometric dating is accurate”

  1. Don’t show an interest in matches that you aren’t really interested in. You’ll be able to communicate with them enthusiastically, rather than feeling obligated. It’s usually not personal (they won’t have known you long enough to know the ‘real’ you).
