My student Erin Barr's work (whilst at the ANU) on 14C and pangolins is out! It works as a cool dietary isotope. These insectivores look such individuals in what they choose to eat. What are the implications for conservation? @sf14c.bsky.social @unioxarchaeology.bsky.social @isotopesuk.bsky.social

Archaeology isn’t just about the past. @oxfordarchaeology.bsky.social's Prof Shadreck Chirikure is uncovering how ancient technologies, manufacturing and repair cultures could help tackle today’s challenges - from sustainability to inequality. Read more ⬇️ bit.ly/4tIL6it
Portrait of Professor Shadreck Chirikure smiling at the camera, wearing a dark blazer and white shirt, against a wooden background. Text on the image reads: “Professor Shadreck Chirikure: How archaeology can take us back to the future.” University of Oxford branding appears at the bottom.
