Fossils inside rock have been clearly visualized utilizing an X-ray interferometer. Two types of clear images are obtained, one involves phase contrast in interference beams and the other involving refraction contrast in forward-diffracted beams. 2D monochromatic synchrotron X-ray radiation with a beam size of 10 mm x 10 mm and a photon energy of 35 keV was used. Using a stereographic pair of X-ray images, the locations of fossils inside rock can easily be determined with a precision of 0.5 mm. This method can be a powerful nondestructive tool in the fields of paleontology and paleobiology to discover and locate fossils and trace fossils inside rock.
