Carbon dating on live things

It is also standard to coat fossils during their extraction and transport.

Acetone is sometimes used while extracting fossils, because it dissolves dirt.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

Other radiometric dating methods such as potassium-argon or rubidium-strontium are used for such purposes by those who believe that the earth is billions of years old.

Radiocarbon is not suitable for this purpose because it is only applicable: a) on a time scale of thousands of years and b) to remains of once-living organisms (with minor exceptions, from which rocks are excluded).

The field of radiocarbon dating has become a technical one far removed from the naive simplicity which characterized its initial introduction by Libby in the late 1940's.

It is, therefore, not surprising that many misconceptions about what radiocarbon can or cannot do and what it has or has not shown are prevalent among creationists and evolutionists - lay people as well as scientists not directly involved in this field.

That causes a dating problem with any animal that eats seafood. After about ten half-lives, there's very little C14 left.

So, anything more than about 50,000 years old probably can't be dated at all.

Recall that atoms are the basic building blocks of matter.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.

If you hear of a carbon dating up in the millions of years, you're hearing a confused report. Second, they rarely contain any of the original carbon.
