The Ditsong National Museum of Natural History, formerly the Transvaal Museum, is a natural history museum situated in Pretoria, South Africa. The museum curates large collections of Plio-Pleistocene fossils, including hominids from Sterkfontein, Swartkrans and Kromdraai in the Cradle of Humankind, as well as late Permian therapsids (mammal-like reptiles from the Karoo). The most complete skull of an Australopithecus africanus specimen, Mrs Ples, is on display in the museum. In addition, Ditsong houses extensive collections of mammals, birds, reptiles, and invertebrates. The museum is located on Paul Kruger Street, between Visagie and Minnaar Streets, opposite the Pretoria City Hall.
