The Elgin marvel: using magnetic resonance imaging to look at a moldic fossil from the Permian of Elgin, Scotland, UK.
The successful use of magnetic resonance imaging (MRI) of a moldic fossil dicynodont from the Permian aeolian Hopeman Sandstone Formation of Elgin, Scotland, UK, provides paleontologists with a nondestructive technique for examining fossils preserved in this fashion. For large moldic fossils, medical scanners such as the Phillips Gyroscan MRI, provide adequate resolution for gross morphologic determination. The 3-D rendered images using software such as Philips Easivision allows the fossil to be examined and dissected without causing any physical damage to the original material. From the scans it is also possible to produce 3-D stereolithographs for a more tactile manipulation of the renderings.
