Turkana Boy

Popular name for KNM-WT 15000, found by Kamoya Kimeu, an almost complete skeleton of a 11-12-year-old boy from West Lake Turkana, Kenya, and attributed to either Homo ergaster or Homo erectus. The site, found in 1984, is dated to about 1.6 mya. The boy was about 160 cm tall (5’3”) at the time of his death, with a cranial capacity of 884 cm3; as an adult he would have been about 185 cm tall (6’1”), with a cranial capacity of about 910 cm3. Like some of the australopithecines, he also possessed six lumbar vertebrae, instead of five as in modern humans. A suggested cause of death is septicemia secondary to dental abscess.
