Ardipithecus Kadabba Haile-Selassie, Suwa, And White, 2004

Provisional species of fossil hominid dating from 5.8-5.6 mya. Six specimens were recovered in 2002 from Asa Koma Locality 3, in the Middle Awash region of Ethiopia; the holotype is ASK- VP-3, and consists of six isolated teeth. A. kadabba has a canine-third premolar honing complex that approximates that of extant and fossil apes, and is thereby distinct from A. ramidus. Specimens described in 1961 from Ardipithecus ramidus kadabba are now referred to this new species. A. kadabba may be sufficiently similar to Orrorin tugenensis and Sahelanthropus tchadensis to warrant the latter’s collapse into a single genus, Ardipithecus.
