On rare occasion, archaeological deposits can accumulate up against a petroglyph panel, concealing part or all of the art.
In that case, it may be possible to discern a minimum age for the art because its creation had to precede the archaeological deposit covering it.
Compared to subsequent periods, the older Holocene Wet Phase Neolithic images usually have a patina that formed after the art and is evenly dispersed over both the images and the background.
Later petroglyph artists took advantage of desert varnish, a dark, often shiny glaze that forms on rock surfaces in very arid environments.
The climate was not stable, however, and around 7000 BCE, monsoon patterns shifted northward, causing the Arabian Peninsula to be more like a savanna than a desert.
Relative dating, although somewhat less satisfying than absolute dating in terms of precision, is considerably more successful for petroglyphs.
The Holocene Wet Phase, as it is called, fluctuated greatly between humid and dry periods and then reverted to a more consistent arid condition around 3800 BCE, as the rain belt retreated southward (Parker et al. The oldest known petroglyphs in Saudi Arabia are believed to date to the Neolithic period or Early Arabian Pastoral, which appears to coincide with at least part of the Holocene Wet Phase.
These images are typically carved or pecked deeply into the rock surface.
Given the current status of direct chronometric dating methods for Arabian petroglyphs, it is rare that the precise age of a rock art panel can be determined.
However, all is not lost, and it is possible to establish a temporal sequence that can be quite edifying.
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.
