For a non-exhaustive list of relative dating methods and relative dating applications used in geology, paleontology or archaeology, see the following: Same as geologists or paleontologists, archaeologists are also brought to determine the age of ancient materials, but in their case the areas of their studies are restricted to the history of both ancient and recent humans.

Thus, to be considered as archaeological, the remains, objects or artifacts to be dated must be related to human activity.

For example, in a stratum presenting difficulties or ambiguities to absolute dating, paleopalynology can be used as a relative referent by means of the study of the pollens found in the stratum.

This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time.

It was the case of an 18th-century sloop whose excavation was led in South Carolina (United States) in 1992.

Thus, from the oldest to the youngest, all archaeological sites are likely to be dated by an appropriate method.

These processes result in All of these processes confuse the stratigraphic record.

In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.

But this method is also useful in many other disciplines.

In other words, they may no longer be in their primary context.

When the bones of our early ancestors are found in the same geological strata as those of other animals that are known to have lived only during a specific time period in the past, we assume that these ancestors must also have come from that time.

For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.

However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..

The stratigraphy of an archaeological site can be used to date, or refine the date, of particular activities ("contexts") on that site.
