Your donation will help ensure that Australia’s fossil, cultural and natural heritage is not lost to science or the Australian community but discovered, preserved and accurately documented for perpetuity. South west Queensland, is a unique region of Australia with so much still to be discovered and recorded... the history books on Outback Gondwana are yet to be written.

Named after ANZAC day having been being discovered on this day in 2006. At the June 2010 dig it became clear that Zac is one of Australia’s most complete sauropods with over 60 bones already discovered. For the scientifically minded, Zac is the only known articulated skeleton of a sauropod from the Cretaceous Period of Australia. Zac is most likely a new genus and species of dinosaur.
Location: West of Eromanga, South-west Queensland, Australia.
Age: Approximately 95-98 million years ago: Cenomanian Epoch , mid-Cretaceous Period.
Size: Based on the remains so far discovered Zac was probably between 15-20m long making it a large sauropod.
Type: Medium-sized plant-eating (herbivorous) sauropod dinosaur.
Formation: Winton Formation, Eromanga Basin.
Classification: It is difficult to determine the classification of Zac because much of the skeleton is enclosed in solid rock, awaiting preparation. Based on specimens so far found Zac will be a peculiar sauropod and unique scientifically, most-likely a species of titanosaur.
Excavation: Excavation of ‘Zac’s’ skeleton only begun in the 2009 field season. The full potential of this dinosaur site is yet to be realized but Paleontologists say these new discoveries confirm that the South-west Queensland sites will be of great significance, not only for Australia, but for the greater understanding of all dinosaurs. Early indications are the ‘Zac’s skeleton is different and even more complete than ‘Cooper’s’.
Two other distinct dinosaurs have been discovered at the Zac site and probably represent a second sauropod of the same species as Zac and a younger individual.
