Sharpening our understanding of saber-tooth biomechanics.

ABSTRACT: Saber-teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber-toothed taxa employed a distinct biting strategy compared to conical-toothed carnivores, like the lion, the precise mechanics and variability of this bite remain debated. In this review, we integrate current knowledge of pointed tooth mechanics and puncture mechanics to explore predatory function, focusing on the canine shear-bite hypothesis. We quantify the key morphological characteristics of saber-teeth-elongation, slenderness, curvature, sharpness, and cross-sectional shape in a sample of saber-and conical-toothed taxa. Using the morphological diversity observed and insights from experimental st
