Telling the story of Central Australia's unique natural and geological history, the exhibitions follow the evolution of the landscape and the fascinating creatures that inhabited it. From the big bang to the present day, meteorite fragments, fossils and interpretive displays detail the geological history of Central Australia. A replica of the ancient Alcoota waterhole, a major scientific site in the region, displays some of the surprising megafauna fossils retrieved from the internationally significant Alcoota fossil site, including a giant freshwater crocodile and the largest bird that ever lived.
