Homo rudolfensis is a fossil hominin species discovered by Bernard Ngeneo, a member of a team led by anthropologist Richard Leakey and zoologist Meave Leakey in 1972, at Koobi Fora on the east side of Lake Rudolf (now Lake Turkana) in Kenya. The scientific name Homo rudolfensis was proposed in 1986 by V. P. Alexeev for the specimen Skull 1470 (KNM ER 1470). Skull 1470 has an estimated age of 1.9 million years.
