X-rays reconstruct ancient primate fossil

A mouse-sized fossil from China has provided remarkable new insights into the origin of primates.

At 55 million years old, it represents the earliest known member of this broad group of animals that includes humans.

The European Synchrotron Radiation Facility in Grenoble, France, used brilliant X-rays to more fully visualise the creature's skeleton.
