Turkana boy, or Nariokotome boy, is the fossil KNM-WT 15000. It is a nearly complete skeleton of a hominid who died in the early Pleistocene 1.5 million years ago (mya), near present-day Lake Turkana in northwest Kenya. This specimen is the "most complete early human skeleton ever found". It was first classified as "Homo erectus"; after much heated debate, it was re-classified as "Homo ergaster".
