FIGURE 17. Ultrastenos huberi, pterygoid fragments. A in A reinterpretation and taxonomic revision of Ultrastenos willisi Stein, Hand and Archer, 2016, a short-snouted mekosuchine crocodylian from the Oligocene of northern Australia
FIGURE 17. Ultrastenos huberi, pterygoid fragments. A: QM F42665, right pterygoid in articulation with right ectopterygoid in ventral view. B: QM F31076, pterygoid pair in ventral view. Abbreviations: ect, ectopterygoid; ecss, sutural surface for articulation with the ectopterygoid; palss, sutural surface for articulation with the palatine; sofm, margin of the suborbital fenestra; vptr, ventral pterygoid ridge.

Figure 3. P in Mammals with a long diastema typically also have dominant masseter and pterygoid muscles
Figure 3. P/A = 3/7. Lengthening the jaw (from i to i′′′) increases A (to A″″). Rotation of the vector (from Post to Ant) increases the length of P (to P′′′) and changes the length of A″″ (to A′′′′′′′′′). P′′′/A′′′′′′′′′ = 3/7.
Figure 1 in Mammals with a long diastema typically also have dominant masseter and pterygoid muscles
Figure 1. The distances from the jaw joint to the third molar (Jm) and the length of the tooth row (mi) are both projected onto lines that are perpendicular to the arrow that represents the resultant vector of jaw muscle force. The ratio of P to A is 3: 7.
