Extended Data Fig. 2: Biomechanical analysis results of cynodont and mammaliaform taxa for simulated unilateral biting at canines and last tooth.

Extended Data Fig. 2

Results for models scaled to the same size (with T. liorhinus as reference). ag, Multibody dynamics analysis plots showing bite forces and joint forces (working and balancing side) during jaw opening and closing cycles. Range bars denote values obtained from reaction forces of finite element models. Peak values represent maximum bite force obtained from multibody dynamics analysis models. hn, Finite element von-Mises-stress contour plots for bite at canine and last tooth (indicated by red arrows). Scale bars in h, jn, 10 mm; i, 50 mm. Sample size for each species, n = 1.
