Wow! Alison Fisk on Bluesky today showing "An extraordinary Acheulean handaxe knapped around a fossil shell c. 500,000-300,000 years ago!"That's some serious dedication to the art of the craft. They wanted that shell to be in the hand axe. Of that I have no doubt.https://bsky.app/profile/alisonfisk.bsky.social/post/3lyppyz3pu22x#Archaeology #Knapping
