Prearticular fragment from specimen GZG.V.29285 A, position of the three scans of this fragment, with the scan used in this figure highlighted in red. B, buried odontode showing extensive apical resorption, as well as reorption from the pulp cavity. C, transverse section from scan, showing semibasal reorption (left) and three other partially resorbed odontodes; the partially resorbed odontode in the top right is the same as in B.
