You may find it useful for the clear definitions, and for excellent links on a variety of topic.

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.

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.

An example of a practical application of seriation, is the comparison of the known style of artifacts such as stone tools or pottery.Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history, archaeology, geology, paleontology, astronomy and even forensic science, since in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred.Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.It is commonly assumed that if the remains or elements to be dated are older than the human species, the disciplines which study them are sciences such geology or paleontology, among some others.Nevertheless, the range of time within archaeological dating can be enormous compared to the average lifespan of a singular human being.
