Fig. 3. Schematic indicating the location of nodes sampled for further analysis. (A) Schematic in left lateral view, with the location at which nodes were sampled within the frontal bone indicated by `fri'. This view also indicates the location of the plane across which the endocranium was `opened' in order to visualize principal strain patterns on the roof of the endocranial cavity. (B) View of the internal surface of the calvaria, with the dark gray area indicating the region of the endocranium that was sampled for the analyses presented in Tables 2 and 3 and Tables S2 and S3 in the supplementary material, and illustrated in Figs 4 and Fig. S1 in the supplementary material. fps, frontoparietal suture; ifs, interfrontal suture.
