Kenyanthropus is a 3.5 to 3.2 million year old (Pliocene) extinct hominin genus that was discovered in Lake Turkana, Kenya in 1999 by Justus Erus, who was part of Meave Leakey's team. The fossil found features a broad flat face with a toe bone that suggests it probably walked upright. Teeth are intermediate between typical human and typical ape forms. Kenyanthropus platyops, which means "Flat faced man of Kenya", is the only described species in the genus. However, if some paleoanthropologists are correct, Kenyanthropus may not even represent a valid taxon, as the specimen (KNM-WT 40000) is so distorted by matrix-filled cracks that meaningful morphologic characteristics are next to impossible to assess with confidence. It may simply be a specimen of Australopithecus afarensis, which is kno
