Fig. 6 in Reconstructed masticatory biomechanics of Peligrotherium tropicalis, a non-therian mammal from the Paleocene of Argentina

Fig. 6. Results of closed gape minus open gape analysis of orthal bite force (BF) for Peligrotherium tropicalis Bonaparte, Van Valen, and Kramarz, 1993. A. Lower left working-side hemimandible of P. tropicalis shown in closed gape (CG) and open gape (OG) position, postcanine crown surfaces are colorized by relative orthal BF (warmer colors represent higher relative orthal BF, and correspond among the taxa seen in Fig. 12). B. Violin boxplot showing distribution of total CG minus OG BF and its orthal component marginal over all locations in the woking-side postcanine toothrow. C. 2D histogram plot showing distribution of estimated bifulcral force magnitudes for CG and OG, as a function of mesiodistal location (MDL). JF-W/B, working-/balancing-side joint force.
