Didier Neraudeau, French palaeontologist at the University of Rennes, France, holding pieces of amber. In 2004, Neraudeau discovered feather fragments in clear amber that may have originated from primitive birds or feathered dinosaurs. In 2008, the amber was X-rayed at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The X-rays produced here are one thousand billion times more powerful than hospital x-rays. The sample was X-rayed at multiple angles to create virtual slices. These were reconstructed into a 3-D computer model (see image E445/329).
