Enamel hypoplasia in the South African Plio-Pleistocene fossil hominid sample is examined. The Swartkrans hominids are shown to have a higher incidence of hypoplasia than the Sterkfontein hominids. Within the Swartkrans sample, individuals with hypoplasia of the first upper molar have lower-than-expected ages of death. Possible taphonomic explanations for these observations are discussed.
对南非上新世-更新世化石原始人类样本中的牙釉质发育不全情况进行了研究。结果显示，斯瓦特克朗斯原始人类的牙釉质发育不全发生率高于斯特克方丹原始人类。在斯瓦特克朗斯样本中，上颌第一磨牙出现发育不全的个体的死亡年龄低于预期。文中讨论了对这些观察结果可能的埋藏学解释。
