Taxon	Specimen	Years
Australopithecus anamensis	KNM-KP 31712	2.80
	KNM-KP 34725	3.63 (5)/4.25 (6)

	DNH 44	1.70
	DNH 47	0.67–0.77
	DNH 84	2.24
	DNH 107	4.82
	DNH 108	5.35/5.53
South African Homo	DNH 35	2.18

Details for individual calculations are given in Table E in S1 File. Ages for KNM-KP 34725, DNH 83, and KB 5223 are given for multiple periodicity values shown in parentheses (which should be considered alternative ages rather than error ranges). The age range for each periodicity value in KB 5223 also reflects some uncertainty in the age of an accentuated line matched across the dentition. The age range for TM 1536 represents estimates derived from lower central incisor initiation ages for two P. robustus specimens. The age range for DNH 47 reflects some uncertainty in postnatal long-period line number. The age range for DNH 108 reflects some uncertainty in the age of an accentuated line matched across the dentition. Due to taxonomic uncertainty, the age for StW 151 is based on estimates of average cuspal enamel secretion rates from A. africanus (from ref. [53]) and South African Homo (measured directly during this study), which should be considered alternative ages rather than error ranges.
