Figure 20. Tapuiasaurus macedoi (MZSP-Pv 807). Upper teeth, wear pattern. A, right premaxilla and maxilla in oblique anterolateral view, with blown up images of maxillary teeth 3 (left) and 2 (right) showing labial wear facets. B, right premaxilla and maxilla in oblique ventromedial view with blown up images of maxillary teeth 2 (left) and 3 and 4 (right) showing lingual wear facets. Both labial and lingual facets are present on right premaxillary teeth 2 and 4 and right maxillary teeth 2 and 3. Note that A and B were photographed at different stages of preparation; A was shot before matrix on the lingual faces of teeth was removed. The triangular piece of bone missing from just behind the tooth row in A represents a sample removed for analysis. Scale bars are for images of the premaxilla and maxilla; teeth are not to scale.
