Dear Isogeochemists,
Has anyone conducted isotopic analyses on carbonate eggshell protein 
and lipids that have separated the two components. How do the isotope 
ratios of protein and lipids change in older (fossil and subfossil), 
and how does that diagenesis (if any) affect the C/N ratios of the 
bulk organic matter.

Any advice, knowledge, or references would be greatly appreciated!
Cheers,
Bill
