By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down.

If the archaeologist finds a sample suitable for carbon dating, then an absolute date may be assigned to an object. This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
This evaluation of the rocks and fossils in the relative dating is known as the biostratigraphy. Fluctuating levels can skew results — for example, if an item went through several high radiation eras, thermoluminescence will return an older date for the item.
