I didn’t make this fine animation, it is the work of José-Manuel Benito Álvarez, check at Wikimedia Commons and at Wikipedia. But I did take the photo, before, I have to admit, I really got it. You see, I’m fond of stone, and the reddish-orange silicified sandstone (quartzite) at Wadi Abu Subeira, near Aswan in Egypt, makes my heart jump… I guess the Levallois core was prepared in the Middle Palaeolithic, quite some thousands of years ago.

Happy Easter!
