TL;DR: Finite element models of two crania of Macaca fascicularis were developed and it was indicated that the presence of a zygomatico‐temporal suture in the model produced strains more similar to experimental values than a completely separated or fused arch.

TL;DR: This work provides the first comprehensive metric analysis of permanent mandibular molar root morphology in Middle and Late Pleistocene Homo neanderthalensis, and Late pleistocene (Aterian) and recent Homo sapiens, and finds the first molar to have the largest average root surface area in recent H. sapiens and Neanderthals.

TL;DR: This work develops three micro-CT-based FEA models of M. fascicularis skulls ranging in dental age from deciduous to permanent dentitions and validated them against published experimental data to evaluate the hypothesis that strain energy density (SED) magnitudes are high in subadult individuals with resulting bone growth in the supraorbital torus.

TL;DR: The novel use of MDA to investigate the influence of different muscle representations on a macaque skull model, where muscle groups were represented by either a single, multiple, or wrapped muscle fibers, and the impact of varying muscle representation on stress fields was assessed.

TL;DR: The results show that, in G. blacki, the pattern of mandibular root numbers-particularly that of the premolars-corresponds with that of Gorilla gorilla, Pan troglodytes, and Pongo pygmaeus, however, G.blacki can be distinguished from the extant hominids by having relatively higher values for postcanine root length and surface area.
