The Rising Star cave system, part of the Cradle of Humankind World Heritage Site in South Africa, has been well mapped and was explored by cavers for many years, but without any fossils being noted there. That changed in September 2013, when two South African cavers, Rick Hunter and Steve Tucker, entered a remote, unmapped chamber and found the first-known fossil bones of what is now called Homo naledi strewn across its floor.
