New crystalline structures have been observed in argon ion-milled conodont elements from a diverse suite of Ordovician taxa ('Cordylodus robustus', Drepanoistodus suberectus, Panderodus gracilis, Plectodina? sp., Aphelognathus sp., Periodon aculeatus using transmission electron microscopy (TEM). Electron diffraction patterns of albid tissue reveal that the component crystals are extraordinarily large, in the order of hundred(s) of microns. These large albid crystals show typical cancellate...[Show more]
