The Taung Child (or Taung Baby) is the fossilised skull of a young Australopithecus africanus. It was discovered in 1924 by quarrymen working for the Northern Lime Company in Taung, South Africa. Raymond Dart described it as a new species in the journal Nature in 1925.
The Taung skull is in repository at the University of Witwatersrand. Dean Falk, a specialist in brain evolution, has called it "the most important anthropological fossil of the twentieth century."
In the early 20th century, the workers at limestone quarries in Southern Africa routinely uncovered fossils from the tufa formations that they mined. The tufa did not form consistently, and over time cavities were left open and they became beneficial areas for animals to take shelter in. As a result, many bones began to build up in these areas. These areas were mostly sandstone, and they stood in the way of successful mining. So, miners would use explosives to clear these areas, and discard all the debris. However, many fossils began to show up, and these were saved by many of the miners. Many were of extinct fauna, which included baboons and other primates, and the more complete or somehow more interesting fossils were kept as curiosities by the Europeans who managed operations.
In 1924, workers at the Buxton Limeworks, near Taung, showed a fossilized primate skull to E. G. Izod, the visiting director of the Northern Lime Company, the managing company of the quarry. The director gave it to his son, Pat Izod, who displayed it on the mantle over the fireplace. When Josephine Salmons, a friend of the Izod family, paid a visit to Pat's home, she noticed the primate skull, identified it as from an extinct monkey and realised its possible significance to her mentor, Raymond Dart.
Salmons was the first female student of Dart, an anatomist at the University of Witwatersrand. Salmons was permitted to take the fossilized skull and presented it to Dart, who also recognized it as a significant find. Dart asked the company to send any more interesting fossilized skulls that were unearthed.
