The relationships between similar types can sometimes be shown not merely to classify, but also to explain, their development -- which is called seriation.

The same applies to archeological sites, containing rock art like cupules, petroglyphs, pictographs and other prehistoric works.This usually requires what is commonly known as a "dating method".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.Furthermore, despite the widening range of archeological dating techniques - such as radiometric carbon dating, Uranium/Thorium and thermo-luminescence dating - not every work of art can be dated with great accuracy if the geological environment lacks important measurable elements.Thus sometimes, dating is dependent on paleontologist scholarship to provide the historical context against which an artifact's relevance and age can be assessed, through stylistic comparison with cave paintings and engravings at other archeological sites.
