Image: ‘Mrs Ples’ Australopithecus africanus skull
Discovered: 1947 by Robert Broom and John Robinson in Sterkfontein, South Africa
Age: 2.5 million years old
The skull was nicknamed ‘Mrs Ples’ because it was originally considered to be an adult female from the genus Plesianthropus. Later, it was decided that the skull was actually an Australopithecus africanus individual and there is also some debate about whether this skull was that of a female or male.
