Radioactive carbon dating fossils


The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.

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.

Notice the titles of 4 and 6 correspond in both lists, which in the opinion of some, hints strongly that the list with number 5 present was an original list." href="#footnote5_6klbc5d"Why is the information presented in the paper important?

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.

This restriction extends to animals that consume seafood in their diet.
