Extended Data Fig. 7: Sexual dimorphism in P. robustus from DMQ.
From: Drimolen cranium DNH 155 documents microevolution in an early hominin species
Frontal (top row), lateral (middle row) and superior-oblique (bottom row) views of a, c, e, DNH 7 and b, d, f, DNH 155. Note that the face of DNH 7 is detached from the specimen’s neurocranium and neurocranial distortion makes it difficult to join the two pieces. The placement of the face on the neurocranium in lateral and oblique views is heuristic and no morphological assessments reported here are dependent on these cranial parts being properly aligned. Moreover, the lateral view of DNH 7 is a reflected image of the specimen’s right side. DNH 155 is absolutely larger than DNH 7, it exhibits a sagittal crest (red arrows) and strong anteromedial incursion of the superior temporal lines (yellow arrows), and a zygomatic body that projects anterior to the nasal aperture (green arrow). DNH 7 is smaller, it lacks a sagittal crest, has only moderate anteromedial incursion of the superior temporal lines, and its zygomatic body does not project anterior to the nasal aperture. Scale bar = 10mm. Oblique views not to scale.
