This technique relies on the property of half-life.Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope.Radiometric dating is also used to date archaeological materials, including ancient artifacts.Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

For example if you have a fossil trilobite and it was found in the Wheeler Formation.

As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.

By measuring the ratio of the amount of the original radioactive element to the daughter isotope, scientists can determine how many half-lives the element has undergone and from there can figure out the absolute age of the sample.

One way that helps scientists place fossils into the correct era on the Geologic Time Scale is by using radiometric dating.

Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.
