Conodont bioapatite resembles vertebrate enamel by XRD properties

摘要

>XRD properties of Phanerozoic conodont apatite material were studied. It was found out that in terms of crystallinity >the apatite resembles the enamel tissue of modern vertebrates. In terms of crystal lattice, apatite of conodonts is independent of taxa on the one hand and of chemistry of the surrounding rock type on the other hand.
