Histological application of X-ray computed microtomography of conodonts

The Pa-elements of the Early Carboniferous conodont Siphonodella quadruplicata (Branson et Mehl) were studied at the Skyscan 1272 micro-CT. The obtained results demonstrate three groups of tissues. The first one comprises interlamellar tissue possessing lowest radiodensity, the second group consists of lamellar tissue characterized by intermediate radiodensity, and the paralamellar and albid tissues demonstrate the highest radiodensity. The X-ray computed microtomography (micro-CT) allows reconstructing internal composition of the studyied Pa-elements and improving data about interlamellar tissue distribution. The results demonstrate perspectives of using the micro-CT in the histological study of conodont elements.
