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.For example, by using a laser, researchers can measure parent and daughter atoms in extremely small amounts of matter, making it possible to determine the age of very small samples [source: New Scientist].Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.

Unfortunately, these elements don't exist in dinosaur fossils themselves.These artifacts have gone through many carbon-14 half-lives, and the amount of carbon-14 remaining in them is miniscule and very difficult to detect.Carbon dating cannot be used on most fossils, not only because they are almost always allegedly too old, but also because they rarely contain the original carbon of the organism that has been fossilized.Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.Scientists attempt to check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.

The most widely known form of radiometric dating is carbon-14 dating.
