Cradle of Humankind
Malmani dolomites, in Bloubank River valley, about southwest of Swartkrans, part of the Cradle of Humankind World Heritage Site in South Africa. Recreational caving has occurred there since the 1960s. Fossils found (starting in 2013) in the cave were, in 2015, proposed to represent a previously unknown extinct species of hominin named "Homo naledi".
