Which of the following is not a chronometric dating method
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.
Absolute dating utilizes one or more of a variety of chronometric techniques to produce a computed numerical age, typically with a standard error.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.Another way that precise dating can be achieved is if the artist records the actual date of his or her creation, the name of a leader of known reign, or a distinctive historical event, like the inscription shown in the previous chapter about King Yousif Assar Yathar’s invasion of the Najran region in 518 CE.Then, however, it must be clear that the artist is referring to his or her own time, and not providing historical commentary.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 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.
