A PRICELESS fossil of the 3.67-million -year-old ‘Little Foot’ skull was flown from South Africa to a lab near Didcot. With the help of an X-ray, scientists at the British research facility Diamond Light Source, were able to see some microscopic details in the ancient remains that could help unravel key clues to the origins of modern humans. The X-ray work from June 2019 is highlighted in a new paper in e-life published this week which reveals new information about evolution and human origins. The scientists were able to observe and describe the vascular canals that are enclosed in the compact bone of the lower jaw.
