Researchers get the unique opportunity to look at the finest details of the craniodental anatomy of the ‘Little Foot’ skull – and to learn about her life.

The hominid, that lived 3.67 million years ago and is perhaps a human ancestor, experienced two malnutrition events as a child, then possibly had to adapt to a sudden change of diet.

The international team of scientists, that included Stratford, imaged the skull using synchrotron X-ray microcomputed tomography, provided by the UK’s national synchrotron, Diamond Light Source.Their findings were published in the paperLittle Foot skull. Little Foot is an early Australopithecus hominid that was discovered in the Sterkfontein Caves, near Johannesburg, by Professor Ron Clarke, in 1994. Three years later he found the location of the skeleton and the painstaking work began on excavating the specimen. For the next two decades, Clarke and his team went about removing the hominid from the hard cave breccia using a small air scribe.

Unusual wear on her front teeth, as opposed to her molars suggest that Little Foot might have been forced to change her diet.
