Artifacts which can be dated using these methods include ceramics, burned lithics, burned bricks and soil from hearths (TL), and unburned stone surfaces that were exposed to light and then buried (OSL).

Is it not the case that the stone around the Sphinx was in situ or not “exposed to light (then re-buried)”? I’m assuming OSL is the technique since afaik the Sphinx structure wasn’t burned (TL)?

I see articles that OSL confirms established dates, just not sure how the exposed-to-light-then-reburied works. We know the Sphinx was buried in the late 18th century, but obviously had been uncovered at some point before that in order to be built - what effect would that have on the OSL dating?
