Tugen Hills
The Tugen Hills are a series of hills in Baringo County, Kenya. They are located in the central-western portion of Kenya.
The Tugen Hills represent one of the few areas in Africa preserving a succession of deposits from the period of between 14 and 4 million years ago, making them an important location for the study of human evolution. Excavations at the site conducted by Richard Leakey and others have yielded a complete skeleton of a 1.5-million-year-old elephant, a new species of monkey and fossil remains of hominids from 1 to 2 million years ago.
Six-million-year-old hominid fossils were discovered here in 2000 by Brigitte Senut and Martin Pickford; the species was named Orrorin tugenensis after the location. This was the oldest hominid ever discovered in Kenya, and the second oldest in the world after Sahelanthropus tchadensis.Footnotes
