Mandibular cheek teeth of Soay sheep. a) Macrographs of left mandibular cheek tooth rows (occlusal view) of Soay sheep of different ages at death. Note that the P2 is congenitally absent in the oldest individual and the infundibulum has already been completely (anterior lobe) or largely (posterior lobe) worn away in the first molar. b) Macrographs of different views of the left mandibular M1 and M2 of individual # 79617, age at death 327 days. Arrowheads mark the cuspalmost and apicalmost positions of the crown root border in the M1
