Morphometry of the mandibular corpus and symphysis in G. freybergi and O. macedoniensis.

a, Bivariate plot of the mandibular tooth row of G. freybergi (black) and O. macedoniensis (RPl-54; grey) illustrating the differences in arcade width. The lingual distances between the left and right tooth row are plotted for each tooth position, if preserved. Measurement was done at the lingual sides of the dental cervices. The vertical axis shows the measuring position along the tooth row given as distance from m3. b, Top: Sagittal sections through mandibular symphyses of O. macedoniensis (RPl-56, RPl 75, RPl-54 [53]). Bottom: Sagittal section through the preserved veneer of the mandibular symphysis of G. freybergi (black) aligned to the symphysal sagittal section of O. macedoniensis [53] (RPl-54, grey; same scale). AP: Alveolar plane; TP: plane of transverse tori; SP: sublingual plane. The inclination of TP and SP, and the angle between both planes is given for G. freybergi.
