According to a new study published in the US journal PNAS, this would make them older than Dinkinesh, also called Lucy, the world’s most famous Australopithecus fossil.
The research was carried out by a team of scientists from the University of the Witwatersrand in South Africa and the University of Toulouse Jean Jaurès, France.
Experts have found Australopithecus fossils, such as the near-complete skeleton known as Little Foot, to be between 3.4 and 3.7 million years old, rather than between two and 2.5 million years as previously thought. .
The Cradle of Humankind is a UNESCO World Heritage Site in South Africa comprising a number of cave fossil sites, including the Sterkfontein Caves.
The latter became famous for the discovery of the first adult Australopithecus, an ancient hominid, in 1936.
With the new investigation, the fossils found in that deposit are about a million years older.
