This one is a seriously fun read!
This isn't the first archaeological forensics via proteomics paper, but it's the first one I can think of that used old bones(!!) and had this much evidence to support identifications -- old identifications!
Lots to digest here, this isn't a small paper, but worth the time.
Moral of the story might be: we can digest and identify just about anything, and it doesn't really matter how old it is, there is probably trace proteins around and that's all you need today?
