The nickname of the 1.6-million-year-old hominid skeleton found in Kenya is Turkana Boy.
Turkana Boy is the common name for fossil KNM-WT 15000, a remarkably complete skeleton of a young Homo erectus. It was discovered in 1984 by Kenyan fossil hunter Kamoya Kimeu near the Nariokotome River, west of Lake Turkana. The alternative name Nariokotome Boy refers to the same specimen.
The skeleton is especially valuable because it preserves 108 bones and provides an unusually detailed picture of early human anatomy. Researchers estimate that the individual was roughly 7–11 years old when he died. His long legs, relatively narrow pelvis and body proportions show that efficient upright walking was already highly developed.
Turkana Boy is sometimes classified as Homo ergaster rather than Homo erectus, reflecting an ongoing taxonomic debate about early African members of the human lineage. The names Selam, Ardi and Lucy refer to different hominin fossils from different places and periods, not to this Kenyan skeleton.
