I have a new paper with @iondoctor.bsky.social and other MCI, Carnegie Science, and Calvert Marine Museum colleagues where we analyzed 8 and 10 million year old Ecphora shell membranes. We found chitin and various gastropod specific peptides. www.app.pan.pl/article/item...

My second paper with former fellow Tjasa is out now. The focus is about swabbing large plastic art objects to study their surfaces (so that anyone can do it for GCMS) but we also do NPDPI for real-time high-res MS www.nature.com/articles/s40...

The impacts of microCT on preserved proteins is something we probably need to consider in the #palaeoproteomics community as well. theconversation.com/scientists-c...
Scientists could be accidentally damaging fossils with a method we thought was safe
A common scanning method used to create ‘virtual copies’ of precious fossils could be erasing some of the crucial information held within.

Check out our new paper, led by former postdoc and current colleague Daniel Green on 18 Ma proteins in fossil teeth! Tim Cleland, a proteomics wizard, did the measurements. What's the take home? We hope to use protein fingerprints to study mammal and hominin phylogenetics! bit.ly/OldProteome

Two great new studies out in @nature.com today, pushing back the recovery of dental enamel proteins to 21+ million years in the Arctic (www.nature.com/articles/s41...) and 18+ million years in East Africa (www.nature.com/articles/s41...).

Are we ever going to say “Bingo! Dino DNA”? No. But there are other microbio clues about ancient creatures in the rock record, including proteins from 18 million years ago that may help work our relationships of extinct creatures. And it hints there are likely even older protein scraps out there.
