The National Museum of Natural History formerly known as the Transvaal Museum was founded as the Staatsmuseum of the ZAR on the 1st of December 1892. And it has, since then acted as custodian and documentation centre of South Africa?s natural heritage. The Museum?s collections and exhibits include hominid fossils from the Cradle of Humankind World Heritage Site and associated fauna, including Mrs Ples [the nickname attributed to a fossil skull believed to represent a distant relative of all humankind]; fossils, skeletons, skins and mounted specimens of amphibians, fish, invertebrates, reptiles and mammals. The National Museum of Natural History is the only natural history museum in Gauteng and one of the largest in South Africa.
