The paring knife acts as the flake removal, the idea is to simulate more complex core preparation without going through hundreds of dollars of flint 😂

This is weirdly difficult for students at first and speaks to the challenge of spatial reasoning inherent in flint knapping! Even a handaxe was hard on the first try, let alone a levallois

Native Americans invented dice and games of chance more than 12,000 years ago, archaeological study reveals A new study shows that dice and games of chance date back thousands of years earlier than experts previously thought.

An archaeologist searching archives found evidence of binary lots going back nearly 13,000 years, suggesting Native Americans were using probability at the end of the last Ice Age - possibly as a way to make strangers into trading partners.🏺🧪

Protect Chaco Canyon | New Mexico Wild

ACTION ALERT⚠️ Dept. of Interior is trying to rush through a revocation of Biden’s public law protecting lands around Chaco Canyon from new oil/gas leases. They’ve given only 7 day for public comment, during Easter/Passover. Thread 🧵 below on why you should care, but here’s a link to comment! 🏺

Field folks, any advice on the tradeoffs between EOS Arrow vs Bad Elf Flex and similar #GNSS units? I'd love a version I can just clip to my backpack and ignore while using Field Maps or OnPoz on a tablet or phone. Advice for 1-3m and sub-meter RTK versions would be appreciated #GIS 🏺🧪

In 1953 archaeologist Robert Braidwood initiated a debate: what began the domestication of cereals in the Ancient Near East? Was it for bread or beer? Malt & malting was discussed briefly by some of the Braidwood Symposium participants but the "Bread or Beer" debate continues unresolved today. 🏺

🦜🏔️ How did vibrant Amazonian parrot feathers end up in a desert tomb on the Pacific coast of Peru 1,000 years ago? Our new paper on @natcomms.nature.com reveals they didn't just trade feathers, pre-Inca societies transported live macaws and parrots across the Andes!👇 www.nature.com/articles/s41...

Interested to know how widespread eating limpets was- on our cold fringe of the north Atlantic they're regarded as a famine food more commonly used for baiting longlines, but I've tried a few & they're not that bad. Maybe they're just harder to harvest than the usual mussels and whelks?

An adorable #Roman shoe, made for a #baby too young to walk. The shoe imitates the footwear of Roman soldiers (caligae). The cut-out design would have shown off the kid’s socks!

The Bronze Age vs The AI Age
1/ Can archaeology predict the future of Big Tech?

Economists usually look back 50-150 years; archaeologists look back further.
When you look at the Bronze Age Collapse (c. 1200 BCE), are there any parallels to our current AI trajectory?
