Homo naledi
Homo naledi is an extinct species of hominin, provisionally assigned to the genus Homo. Discovered in 2013 and described in 2015, fossil skeletons were found in South Africa's Gauteng province, in the Dinaledi Chamber of the Rising Star Cave system, about 800 meters (0.5 miles) southwest of Swartkrans, part of the Cradle of Humankind World Heritage Site. As of September 2015, fossils of at least fifteen individuals, amounting to 1550 specimens, have been excavated from the cave.The species is characterized by a body mass and stature similar to small-bodied human populations, a smaller endocranial volume similar to Australopithecus, and a skull shape similar to early Homo species. The skeletal anatomy combines primitive features known from australopithecines with features known from early hominins. The individuals show signs of having been deliberately disposed of within the cave near the time of death. The fossils have not yet been dated.Homo naledi was formally described in September 2015 by 47 co-authors proposing the bones represent a new species. Other experts contend more analysis and evidence is needed to support this classification.
