The data from this study lends support to work using more traditional methods that showed bite force to correlate negatively with jaw gape 
. That moving closer to the pivot point of the jaw would increase bite strength is an expected result of the jaw's lever mechanics 
. Although the largest bite force was generated at the shallowest jaw gape, the greatest increase
in bite force did not occur at this angle. Rather it occurred at 25° for the canines and 35° for the carnassials.
It is notable that these angles of high bite force increase also appeared to correlate with regions of the cranium that showed either resistance to the increased force (canine bites), or lowered VM stress (carnassial bites). This suggests that the dingo's skull and musculature may be optimized to deliver maximal bites at these angles, with interesting functional implications. Among subspecies of grey wolf and social canids in general, bite force in the dingo is relatively weak and bite force adjusted for body mass allometry has been shown to correlate with prey size 
. We suggest that optimal gape angle may also be a useful indicator of feeding ecology among carnivorous mammals. Analyses incorporating both large prey specialists (e.g., Canis lupus lupus
, Lycaon pictus)
and small prey specialists (e.g., Vulpes vulpes
) are needed to examine this proposal. Alternatively it could also be that optimality in this range is necessary for disabling bites, such as the severing of major tendons.
As the mandible is the primary object being powered by the jaw muscles, finding higher VM stress in this skull region is not entirely surprising. It is doubtful, however, that stress increase was solely due to the higher bite force attributed to the more acute angles. If bite force itself was the main driver of mandibular stress, then VM stress in the mandible would be greatest in the much stronger carnassial bites. However, a carnassial bite at maximum gape, producing a force 2.7 times higher than the respective canine bite, resulted in mandibular VM stress that was 30% lower than in a canine bite at the same angle. This suggested that dingoes, and perhaps by extension, carnivorans in general, have evolved skulls that are better adapted to tolerate stresses at wider jaw angles than other mammals.
Overall, the results of this study offer support for previous models of mammalian jaw mechanics 
. Bite force is markedly affected by both jaw gape and point of contact along the jaw line. Proximal bites and acute jaw angles result in greater overall force. Even for carnivorans, which have undergone evolutionary adaptations to allow for greater bite forces at wider gape angles, the rules of the models remains true.
In conclusion, while bite force in C. l. dingo appears to still be limited by overall jaw mechanics, the fact that stress data shows greater tolerance of wide jaw angles, indicates the direction taken in carnivoran evolution. Consideration of stress and bite force data, suggests that there is an optimal bite angle of between 25° and 35° in C. l. dingo. Further analyses will be needed to determine whether optimal gape angle might be a useful predictor of feeding ecology.
