The same rock formation also contains a type of trilobite that was known to live to million years ago. Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. Typically commonly occurring fossils that had a widespread geographic distribution such as brachiopods, trilobites, and ammonites work best as index fossils. This light can be measured to determine the last time the item was heated. This process frees electrons within minerals that remain caught within the item. Carbon, the radioactive isotope of carbon used in carbon dating has a half-life of years, so it decays too fast. This makes it ideal for dating much older rocks and fossils. This technique is based on the principle that all objects absorb radiation from the environment. This technique relates changes in amino acid molecules to the time elapsed since they were formed. The amount of luminescence released is used to calculate the equivalent dose De that the sediment has acquired since deposition, which can be used in combination with the dose rate Dr to calculate the age.

    These isotopes break down at a constant rate over time through radioactive decay. So, how do we know how old a fossil is?

    When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization. Carbon, the radioactive isotope of carbon used in carbon dating has a half-life of years, so it decays too fast.

    Index fossils are fossils that are known to only occur within a very specific age range.

    If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil. By measuring the ratio of the amount of the original parent isotope to the amount of the daughter isotopes that it breaks down into an age can be determined.
