As potassium decays, it turns into argon. Afterward, the amount of the radioactive isotope carbon in their remains decreases. Index fossils are fossils that are known to only occur within a very specific age range. Sometimes called carbon dating, this method works on organic material. Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. So, how do we know how old a fossil is? Using relative dating the fossil is compared to something for which an age is already known. For example if you have a fossil trilobite and it was found in the Wheeler Formation. Both plants and animals exchange carbon with their environment until they die.
