Figure 27. Heterodontosaurus tucki Crompton & Charig, 1962. SAM-PK-K1332 (referred specimen). Line drawings based on scanning electron micrograph images of right dentary teeth: De.7–De.9. A, worn surfaces of the teeth in oblique dorsolateral aspect showing the lipped lower edges of the wear facets and the minor imbrication between crowns (the overlap pattern is the reverse of that seen in the maxillary dentition – see Fig. 21B). B, close-up of De.9 to show details of the wear facet and the lower 'lip' at the base of the wear facet. For full list of abbreviations see end of paper.
