Fig. 2 in Dental microwear of a Late Triassic dinosauriform, Silesaurus opolensis
Fig. 2. Non-facet microwear of teeth from the left lower jaw (ZPAL Ab III 361/27) of Silesaurus opolensis Dzik, 2003 from the Upper Triassic; Krasiejów, Poland. Mesial (left), middle and distal (right) teeth have 8, 13, and 8 SEM sites, respectively, shown as open rectangles in the figure, in which scratch angles were measured. The rose diagram located in the middle of each SEM site represents scratch orientations in the site. The black arrow represents a mean vector orientation of each rose diagram. The rose diagram at the base of each tooth represents the scratch orientation of the whole tooth. We could not lay each SEM site horizontal for observation to eliminate effects of mold curvature. Nevertheless, it is clear that scratches are basically oriented in the apico-basal direction for all teeth.
