But this sediment doesn't typically include the necessary isotopes in measurable amounts.

Fossils can't form in the igneous rock that usually does contain the isotopes.

The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

Radiometric dating isn't the only method of determining the age of rocks.

This information has also helped determine the age of the Earth itself.

These layers are like bookends -- they give a beginning and an end to the period of time when the sedimentary rock formed.

By using radiometric dating to determine the age of igneous brackets, researchers can accurately determine the age of the sedimentary layers between them.

Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old.

To determine the ages of these specimens, scientists need an isotope with a very long half-life.

Each of them typically exists in igneous rock, or rock made from cooled magma.
