The thumb, wrist, and palm bones are modern-like while the fingers are curved, more australopithecine, and useful for climbing.The shoulders are configured largely like those of australopithecines.followed by a second expedition in March 2014 for a 4-week-excavation in the Dinaledi Chamber.In total, more than 1,550 pieces of bone belonging to at least fifteen individuals have been recovered from the clay-rich sediments.Francis Thackeray, of the University of the Witwatersrand, suggested that H. habilis, species that existed around 1.5, 2.5, and 1.8 million years ago, respectively. (2017) announced a much more recent age range of between 335,000 and 236,000 years ago from dating fossil teeth, sediments encasing the fossils and overlying flowstone.naledi lived 2 ± 0.5 million years ago, based on the skulls' similarities to H. They used a variety of dating techniques, including radiocarbon dating of teeth, optically stimulated luminescence of sediment, palaeomagnetic analysis of flowstone, and most conclusively, uranium-thorium dating of cave flowstone and teeth and electron spin resonance dating of teeth. naledi, combining more ancestral with more recently evolved features, might result from hybridization between different hominin lineages.

In 2013, fossil skeletons were found in the Gauteng province of South Africa, in the Rising Star Cave system, part of the Cradle of Humankind World Heritage Site about 50 km (31 mi) northwest of Johannesburg.It, and the corresponding name Dinaledi Chamber ("chamber of stars"), were chosen to reference the Rising Star cave system where the fossils were found.On 13 September 2013, while exploring the Rising Star cave system looking for an extension, recreational cavers Rick Hunter and Steven Tucker of the Speleological Exploration Club (SEC) of South Africa found a narrow, vertically oriented "chimney" or "chute", measuring 12 m (39 ft) long with a very narrow width tightening in places to as small as approximately 20 cm (7.9 in).Creative Commons is not a law firm and does not provide legal services.Distributing, displaying, or linking to this Commons Deed does not create an attorney-client relationship.
