The four methods involved in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence while biostratigraphy, stratigraphy, and cross dating are involved in the relative dating.

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. In a hypothetical example, a rock formation contains fossils of a type of brachiopod known to occur between 410 and 420 million years.It is a less advanced technique when compared to absolute dating.Some methods used in relative dating are stratigraphy, biostratigraphy, and cross dating.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.Absolute dating is expensive and takes time while relative dating is less-expensive and efficient.

Absolute dating is the technique that determines the exact age of a historical remaining while relative dating gives the order of age of several samples.

Absolute dating and relative dating are two techniques used in geology to evaluate the age and the period of a fossil or rock. What is Absolute Dating – In geology, absolute dating is a technique that determines the exact numerical age of a historical remaining.

Since it evaluates the exact age of the sample, absolute ageing is also called numerical dating.

Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation.

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

Absolute age is a quantitative measurement while relative age is a qualitative measurement.

    Some isotopes of certain elements are unstable; they can spontaneously change into another kind of atom in a process called “radioactive decay.” Since this process presently happens at a known measured rate, scientists attempt to use it like a “clock” to tell how long ago a rock or fossil formed.
