BBC Science reports that scientists have used high-power X-rays to “see inside” an exquisite and complete dinosaur specimen. The skeleton belongs to a small, plant-eating dinosaur which lived 200 million years ago – at the beginning of the Jurassic . Although this species was widespread at the time, scientists have largely had to rely on incomplete fossils. The analysis was carried out at the ESRF facility in Grenoble, France, and showed that the specimen was juvenile. The skeleton is too small and fragile, and the rocks around it too hard, to allow it to be studied by conventional means. In addition, the rock matrix in which the fossil is preserved contains trapped minerals which prevented it from being scanned in a standard CT scanner.
