Abstract
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.
