Isotope Geochemists,

I am looking for vertebrate bone phosphate samples that are known to be
altered, either by field relationships (in a contact metamorphic zone?) or
some sort of chemical indicator.  I would like to run some O-18 phosphate
analyses on altered bone phosphate.  Does anyone have or know if such
specimens exist?
