It will happen this week at the 7th Congress for Experimental Archaeology. This time organized by @traceolab.bsky.social
I will present how we can use proxies to classify efficiency of Lithic Raw Materials. @humendylab.bsky.social @tracer-leiza.bsky.social @icarehb.bsky.social

Did you ever ask why people used so many different rocks in their tasks?
If you had this question in your mind, go and check my new paper with my colleagues. dx.plos.org/10.1371/jour...
