Largest dataset on Mg/Ca in shells yet (+100 and over a dozen sites)🐚 Again, we found tightly correlated but shell-specific relationships between temperature and Mg/Ca. Lots of potential for future archaeological studies🏺

Excited to share our new publication, led by the amazing Anastasia and @youssefdjellal.bsky.social! We show that CNNs can help not only with classifying traces of use, but also on how to acquire imaging data 🔬 @icarehb.bsky.social @leizarchaeology.bsky.social

Don’t miss this one 👇🏼 join us next year at the @caaint.bsky.social and show us your innovative computer applications to the study archaeological artefacts!

Pioneering animal behavior scholar Jane Goodall.

Anyone wishing a master class on changing the world for the better, without becoming negative, cynical, angry or narrow-minded, could model after Jane Goodall.
