Conodont elements are calcium phosphate(apatite structure)mineralized remains of the cephalic feeding apparatus of an extinct marine *** to the high affinity of apatite for rare earth elements(REE)and other high field strength elements(HFSE),conodont elements were frequently assumed to be a reliable archive of sea-water composition and changes that had occurred during ***,the crystallinity index of bioapatite,i.e.,the rate of crystallinity of biologically mediated apatite,should be generally linearly dependent on diagenetic alteration as the greater(and longer)the pressure and temperature to which a crystal is exposed,the greater the resulting *** this study,we detected the uptake of HFSE in conodont elements recovered from a single stratigraphic horizon in the Upper Ordovician of Normandy(France).Assuming therefore that all the specimens have undergone an identical diagenetic history,we have assessed whether conodont taxonomy(and morphology)impacts HFSE uptake and crystallinity *** found that all conodont elements are characterized by a clear diagenetic signature,with minor but significant differences among *** distinctions are evidenced also by the crystallinity index values which show positive correlations with some elements and,accordingly,with diagenesis;however,correlations with the crystallinity index strongly depend on the method adopted for its calculation.
