dc.description.abstractThe physical extraction of fossilised remains from rocks enables quantitative physiological investi gation of bonedimensions,volume, and porosity, however leads to the destruction of valuable con textual information and soft-tissue remains within the matrix. Conventional and synchrotron-based X-ray computed tomography (XCT) have been utilised for many years as critical tools in uncovering valuable 3-D internal and surface renderings of scientifically important fossils, however poor contrast and X-ray penetration often prevents thorough tomographic analysis. DINGO, Australia’s first and only neutron micro-computed tomography (nCT) instrument, located at the OPAL nuclear research reactor, is being used to obtain unpreceded reconstructions of ex traordinary fossilised anatomical features not visible with conventional imaging techniques. This presentation will outline the physical capabilities of DINGO, the limitations and results to-date in the field of palaeontology. Drawing upon specimens scanned from across Australia, North America, New Zealand, and China, this presentation will demonstrate the complementarity of nCT to classic XCT methods for certain geological formations and fossil localities. nCT has yielded unpreceded contrast and detailed-reconstructions of fossilised soft tissue in a Juras sic cynodont. The stomach contents and digestive function of herbivourous and carnivorous di nosaurs, and a Cretaceous Australian crocodilian have been revealed, providing insights into an cient environments and food chains. In this way, a new species of Australian dinosaur has been discovered. © The Author.en_AU
