@yourimmortal I think that would depend on context preservation (and  security I. E. How likely is it that the context you're sampling includes material from, say, modern contexts) to be honest? I used IRMS and animal bone / teeth,  as I could then use the data to try and build animal management strategies (and I was severely limited on sample numbers and funds!) and compare the profiles for potential movement! The bone provides a lifetime average of the carbon and nitrogen values, and the incremental sampling of the tooth allowed me to build a life history over the formation of that tooth, so comparing the two can help identify significant changes, and thus potentially movement or change in husbandry practice (for example, from an open field to a forest)! I hope that makes sense, I've only just woken up 😂 X
