Figure 2 in The killer's toolkit: remarkable adaptations in the canine teeth of mammalian carnivores

Figure 2. Sharpness measurements (A, B) and landmarking protocol (C) as shown on a jaguar (Panthera onca; NMV R2541) upper canine. The cross-sectional area at 50% of the cusp height is indicated by the yellow line, and the sharpness areas measured are indicated by yellow-outlined areas. The three curves used in three-dimensional geometric morphometric analysis are indicated by red lines, and the landmarks are indicated by dots (blue, fixed landmark; red, sliding semi-landmark).
