For the last 75 years or so, Australia has been a relative wasteland when it comes to sauropod discoveries. That all changed in 2009, with the announcement of not one, but two new sauropod genera: Diamantinasaurus and Wintonititan, comparably sized titanosaurs represented by sparse fossil remains. Like most titanosaurs, Wintonititan probably had a rudimentary layer of armored skin along its back, the better to deter the large, hungry theropods of its Australian ecosystem.
