Rob_H Posted October 9, 2018 Share Posted October 9, 2018 Dear colleagues I found this strange small thin disk on the surface of the sand in the desert in Giza, Egypt (just outside Cairo). It's very thin and has concentric lines, each line being made up of small dots. I can't find anything like it on various fossil sites that I looked at. It's only 2.5cm (one inch) in diameter and very thin. Many thanks to anyone who has the time to reply, even if it's just speculation (it's fun guessing too !)
