Fig. 12. Comparison of orthal bite force (BF) distribution across lower tooth-row at closed gape (CG) and open gape (OG). A. Didelphis marsupialis Linnaeus, 1758, a generalized mammal showing relatively low orthal BF magnitudes at both CG and OG. B. Ursus arctos Linnaeus, 1758, which shows very little ability to preserve high orthal BF at high gape among the therians sampled, but has very high orthal BF at CG. C. Crocuta crocuta (Erxleben, 1777), a taxon capable of preserving a large amount of orthal BF at high gape, and showing similar orthal BF values at CG and OG. Color bar at right is scaled to units of the combined (across-taxa) sample standard deviation in estimated orthal bite force values (generated using all muscle categories, see text). Therefore, colors within the postcanine toothrow correspond to matching, size-scaled, orthal BF magnitudes across all sampled taxa (and in Peligrotherium tropicalis as seen in Fig. 6A). ... : Published as part of Harper, Tony, Adkins, Caleb F. & Rougier, Guillermo W., 2022, Reconstructed masticatory biomechanics of Peligrotherium tropicalis, a non-therian mammal from the Paleocene of Argentina, pp. 177-201 in Acta Palaeontologica Polonica 67 (1) on page 197, DOI: 10.4202/app.00912.2021, http://zenodo.org/record/12198019 ...
