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.

The majority of the time fossils are dated using relative dating techniques.

We define the rate of this radioactive decay in half-lives.

If a radioactive isotope is said to have a half-life of 5,000 years that means after 5,000 years exactly half of it will have decayed from the parent isotope into the daughter isotopes.

Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast.

It can only be used to date fossils younger than about 75,000 years.

This measures the amount of the radioactive isotope carbon-14 (C) in the sample.

These are used to measure fossils older than 50 000 years of age.

The Wheeler Formation has been previously dated to approximately 507 million year old, so we know the trilobite is also about 507 million years old.

But, how can we determine how old a rock formation is, if it hasn’t previously been dated?

The other methods of dating use uranium or plutonium.
