Popis: Alignment procedure carried out before Finite Element Analysis; Case-specific fossil reconstruction procedures applied in some of the fossils to enable Finite Element Analysis.; Detailed description of the Mesh-weighted arithmetic mean (MWAM) and Mesh-weighted median (MWM) statistics.; Mardia’s multivariate test applied to check the assumption of multivariate normality in the distribution of the stress percentiles.; Extra information about how the Intervals’ method was applied to obtain the biomechanical variables subsequently used for fossil classification.; Additional information and brief descriptions of the machine-learning methods that were used to classify the fossil sample.; a) Results of the phylogenetic multiple regression (PGLS) of von Mises stress percentile values on volume (9,999 iterations). This test was carried out to test that the observed differences in von Mises stress results between the different platyrrhine taxa were not merely attributed to size-dependent effects.; Results of the phylogenetic multiple regression (PGLS) of talar shape on centroid size (9,999 iterations) carried out to test that the observed differences in talar shape between the different platyrrhine taxa were not merely attributed to size-dependent effects.; Briefly discussed results for each one of the analysed fossil specimens.
