Homo erectus - Turkana Boy Homo erectus - Turkana Boy skull profile


"Turkana Boy" (KNM-WT 15000)

Discovered by Kamoya Kimeu in 1984 at Nariokotome near Lake Turkana in Kenya. This is an almost complete skeleton of an 11 or 12 year old boy, the only major omissions being the hands and feet. (Some scientists believe H. erectus matured faster than modern humans, and that he was really about 9 years old) It is the most complete known specimen of Homo erectus, and also one of the oldest, at 1.6 million years. The brain size was 880 cc, and it is estimated that it would have been 910 cc at adulthood. The boy was 160 cm (5'3") tall, and would have been about 185 cm (6'1") as an adult. This is surprisingly tall, indicating that many Homo erectus may have been as large as modern humans. Except for the skull, the skeleton is very similar to that of modern boys, although there are a number of small differences.
