Fig. 5. Results of Group 1 (G1) minus Group 2 (G2) analysis of orthal bite force (BF) for Peligrotherium tropicalis Bonaparte, Van Valen, and Kramarz, 1993. A. Lower left working-side hemimandible of P. tropicalis with postcanine crowns colorized by relative G1 vs. G2 advantage (yellow shows areas where G1 produces higher orthal BF, while bluer colors correspond to higher G2 BF values; white areas are where G1 and G2 forces are sub-equal). B. Violin boxplot showing distribution of total GP1 minus GP2 BF and its orthal component marginal over all locations in the postcanine tooth-row (TR). C. 2D histogram plot showing distribution of estimated bifulcral force magnitudes for G1 and G2 muscle recruitment regimes, as a function of mesiodistal location (MDL). JF-W/B, working-/balancing-side joint force.
