       Diamantinasaurus along with Wintonotitan were the first sauropod dinosaurs discovered in Australia since the discovery of Austrosaurus over seventy-five years earlier. Diamantinasaurus has the nickname 'Matilda' and this along with the type species D. matildae, are in reference to the folk song 'Waltzing Matilda'.
       Much of the skeleton of Diamantinasaurus is still unknown. There is no known skull, and the vertebrae are missing. Only parts of the limbs, ribs, shoulder blade have been recovered, but they do indicate that Diamantinasaurus was one of the titanosaurids. They also show the presence of a thumb claw, something which is not normally seen in titanosaurians.
       Another dinosaur, the theropod Australovenator was also found in close proximity to the remains of Diamantinasaurus.
