Last week, scientists announced the discovery of a remarkably 1 well-preserved skeleton of what might be a new species of an ancient hominid that lived almost 2 million years ago.
The bones were found in 2008. This February, they were analyzed 2 by one of the highest-tech tools available, the synchrotron at the European Synchrotron Radiation Facility in Grenoble, France. The device uses beams of x-rays a trillion times brighter than medical x-rays, and produces images at the atomic level.
Paleontologist Paul Tafforeau developed a technique to use the synchrotron to study fossils even still partially 3 entombed—with resolution at the micron scale.
Fossils of the age and significance of the new find are rarely moved. But discoverer Lee Berger oversaw 4 the careful transport of the skull 5 and skeleton fragments from South Africa to France for a two-week intensive study.
The preliminary analysis has turned up fossilized insect eggs, left by ancient bugs 6 that may have fed on the decomposing 7 corpse 8. There’s also a region of low-density that could be a section of the hominid’s brain. The researchers hope that the synchrotron ultimately supplies what used to be impossible-to-get details about our distant relative.
