Description
TABLE 3. — Dental developmental stages of OMO 362-10001 and a comparative sample of Paranthropus, based on Moorrees et al. (1963) scale. Age at death are provided by Dean (1987) and Smith et al. (2015b). DNH 47, DNH 44, DNH 84, SK 62 developmental stages are from Braga et al. (2023); KNM-ER 1477 and KNM-ER 1820 developmental stages are from Braga & Moggi-Cecchi (2025). OMO 362-10001, KW 9000, and DNH 108 developmental stages were acquired by the authors. *, indicates estimated age, see text; 1, emerged M1; 0, M1 not emerged.
