English term or phrase:propagation phase contrast microradiography
Opaque amber represents more than 75% of the amber found in sites from the Cretaceous period (from135 million to 63 million years ago), a time that saw the disappearance of dinosaurs and the emergence of modern insects and flowering plants. However, studying this kind of amber has proved difficult, since the presence of fossils cannot be determined with the naked eye.
To find out what was inside the stone, Ms Lak and her colleagues and Dr Paul Tafforeau of the ESRF, along with researchers from the National Museum of Natural History of Paris, made use of the synchrotron X-ray imaging technique ** 'propagation phase contrast microradiography' **. The technique permits light to reach the interior of this dark amber. 'Researchers have tried to study this kind of amber for many years with little or no success,' explains Dr Tafforeau. 'This is the first time that we can actually discover and study the fossils contained within.'
