DESCRIPTION:Speakers: Joseph Bevitt (Australian Nuclear Science and Techno
 logy Organisation)\nThe physical extraction of fossilised remains from roc
 ks enables quantitative physiological investigation of bonedimensions\,vol
 ume\, and porosity\, however leads to the destruction of valuable contextu
 al information and soft-tissue remains within the matrix.\nConventional an
 d synchrotron-based X-ray computed tomography (XCT) have been utilised for
  many years as critical tools in uncovering valuable 3-D internal and surf
 ace renderings of scientifically important fossils\, however poor contrast
  and X-ray penetration often prevents thorough tomographic analysis.\nDING
 O\, Australia’s first and only neutron micro-computed tomography (nCT) i
 nstrument\, located at the OPAL nuclear research reactor\, is being used t
 o obtain unpreceded reconstructions of extraordinary fossilised anatomical
  features not visible with conventional imaging techniques. This presentat
 ion will outline the physical capabilities of DINGO\, the limitations and 
 results to-date in the field of palaeontology. Drawing upon specimens scan
 ned from across Australia\, North America\, New Zealand\, and China\, this
  presentation will demonstrate the complementarity of nCT to classic XCT m
 ethods for certain geological formations and fossil localities.\nnCT has y
 ielded unpreceded contrast and detailed-reconstructions of fossilised soft
  tissue in a Jurassic cynodont. The stomach contents and digestive functio
 n of herbivourous and carnivorous dinosaurs\, and a Cretaceous Australian 
 crocodilian have been revealed\, providing insights into ancient environme
 nts and food chains. In this way\, a new species of Australian dinosaur ha
 s been discovered.\n\nhttps://events01.synchrotron.org.au/event/84/contrib
