Time chart of “possible” early hominin species.

Orrorin

The second oldest potential primitive hominin species is Orrorin tugenensis, the name given to fossils found in sediments in the Tugen Hills of northern Kenya. Its age has been determined using potassium/argon dating to around 6 mya. One specimen, a lower molar tooth crown, was discovered in 1974, and twelve other specimens have been discovered since 2000.

The evidence for O. tugenensis is still frustratingly fragmentary. Its discoverers, Brigitte Senut and Martin Pickford, two paleoanthropologists based at the Collège de France in Paris, base their conclusion O. tugenensis is a hominin on two lines of evidence, one cranial, the other postcranial.
