Figures
Figure 1
2D sections of the roots of the upper right first molar (A,B), of the cranial vault (C,D), and of the mandibular symphysis (E) of StW 573.
The close up (B) of the roots of the upper right third premolar shows the dentine–cementum junction. The Haversian canals of the mandibular symphysis is reconstructed in 3D (F) in the same orientation as in (E). 1: dentine; 2: cementum; 3: calcite; 4: trabecular bone; 5: incremental line in the cementum; 6: diploic bone; 7: inner table; 8: diploic channel; 9: outer table; 10: Haversian canals; 11: dichotomous branching; 12: transverse connection.
Figure 2
3D renderings of the buccal aspect of the enamel surface of the lower left canine of StW 573 using synchrotron-based data sets at 21.23 (A) and 7.91 µm (B).
The black arrows (A) point to enamel defects. 3D reconstructions are superimposed (C) and the distances between them are rendered by a pseudo-color scale ranging from dark blue (lowest values) to red (highest values).
