Radiocarbon dating bone
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).
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.
The LMW fraction was found to exhibit different values from those of the other fractions, indicating the possible presence of extraneous contamination.
The Vivaspin™ 6 ultrafilters used in this study were analyzed and radiocarbon dated both before and after cleaning.

In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.
