Relative dating erosion
The patina is darker on the older images and the newer images are brighter.
Although it is difficult to state the absolute ages of most of the rock art studied in this project, there are certainly general trends, best estimates and bracketing dates, which will be provided whenever possible.
The earth at that time was considerably colder and the ice caps were much larger than they currently are.
Many species, such as mammoth and woolly rhinoceros thrived in Eurasia and the mammoth, mastodon, camel and giant sloth lived in North America.
Around 10,0000 BCE, a significant climate change occurred, altering environments, flora, and fauna in most parts of the world.
Following the Pleistocene, the Holocene or Recent epoch, witnessed a marked global warming that we still experience today.
The relatively high frequency of hunting scenes in contrast to pastoral ones could also reflect the greater risk invested in hunting forays, and therefore perhaps more accompanying rituals.
Wild species targeted as prey by Neolithic hunters included: the aurochs (now extinct large-horned wild cattle), onager, ibex, bezoar goat, oryx, addax, and gazelle.
Then, however, it must be clear that the artist is referring to his or her own time, and not providing historical commentary.Different researchers have applied a variety of absolute dating methods directly to petroglyphs or to sediments covering them, including AMS (accelerator mass spectrometry) radiocarbon, cation ratio, amino acid racemization, OSL (optically stimulated luminescence), lichenometry, micro-erosion and micro-stratification analysis of patina. These techniques have yielded mixed results in terms of reliability and feasibility, but, in any case, none has been applied to date in Saudi Arabia.It is hoped that absolute dating will be successfully implemented in the future in this region.Clues to relative dating include: the manufacturing technique used; the patina covering the art; the layering of figures on top of each other; the style of human forms; and the particular animal species, types of artifacts and subject matter shown.For some 20,000 years, during the Late Pleistocene epoch (Ice Age), the Arabian Peninsula was overall very arid, as it is today.
