First glimpse of intricate details of Little Foot’s life

In June 2019, an international team brought the complete skull of the 3.67-million-year-old ‘Little Foot’ Australopithecus skeleton, from South Africa to the UK and achieved unprecedented imaging resolution of its bony structures and dentition in an X-ray synchrotron-based investigation at Diamond. The X-ray work is highlighted in a new paper in e-Life, published today focusing on the inner craniodental features of ‘Little Foot’. The remarkable completeness and great age of the ‘Little Foot’ skeleton makes it a crucially important specimen in human origins research and a prime candidate for exploring human evolution through high-resolution virtual analysis.

To recover the smallest possible details from a fairly large and very fragile fossil, the team decided to image the skull using synchrotron X-ray micro computed tomography at the I12 beamline at Diamond, revealing new information about human evolution and origins. This paper outlines preliminary results of the X-ray synchrotron-based investigation of the dentition and bones of the skull (i.e., cranial vault and mandible).
