Of long dead fishes, brains and teeth... How X-ray tomography applied to Australian fossil fishes improved our knowledge of the jawed vertebrate emergence

Dr Vincent Dupret has been working on the origin of gnathostomes (jawed vertebrates), and especially the evolution of anatomical features surrounding this astonishing event which occurred 450 million years ago.
Very well preserved Australian fossil fish from various localities (Wee Jasper, NSW, and Gogo Formation, WA) were scanned, processed and rendered in our facilities (CTLAb, Applied Maths, ANU, etc.) or at the Australian Synchrotron (Melbourne). His study focused on  the internal structures of the braincase or the teeth in a key group of armoured fossil fishes, the placoderms, which are the first jawed vertebrates.
Beyond anatomical and evolutionary outputs, Dr. Dupret wishes to acknowledge the joint efforts and collaborations sustained at the Department of Applied Mathematics and Vizlab, which resulted in mutual benefits.
