Figure 9. Maxillary dentition and tooth wear of Shunosaurus lii (ZG65430). A, sagittal cross-section of a maxillary tooth in alveolus showing the relative depth of the lingual and labial walls; the missing interdental plate gives a pleurodont-like tooth implantation. B, the same jaw section when the interdental plate is restored in place, showing typical thecodont implantation. C, lingual view of the left maxilla showing tooth wear facets, replacing teeth, and interdental plates.
