Figure 1 in Comparative bite forces and canine bending strength in feline and sabretooth felids: implications for predatory ecology

Figure 1. Skulls of sabrecat Smilodon populator in (A) lateral, (C) ventral, and (E) posterodorsal views, and of lion (Panthera leo) in (B) lateral, (D) ventral, and (F) posterodorsal views, to scale. Shaded areas in (C) and (D) represent the reconstructed cross-sectional area of the masseter–pterygoideus muscle groups, and in (E) and (F) represent the temporalis. The resultant force vector of the masseter–pterygoideus (M) acts through the centroid (white circle in C and D) with an inlever moment arm Im about the temporomandibular joint, and the resultant force vector of the temporalis (T) acts through the centroid (black circle in A and B, white circle in E and F) with an inlever moment arm (It) about the temporomandibular joint.
