From: Drimolen cranium DNH 155 documents microevolution in an early hominin species

Right lateral views of P. robustus specimens a, DNH 7, c, SK 48, e, SK 52, f, SKW11, and g, SK 12. Left lateral views of b, DNH 155, and d, TM 1517. Vertical red lines pass through P4/M1 on each specimen. The anterior aspect of the root is positioned at this line in a and b but anterior to the line in c–g. Scale bar = 10mm.
