abc.net.au/news/queensland-sauropod-dinosaur-skull-found/102198990The nearly complete skull of a 95-million-year-old sauropod dinosaur named "Ann" found in Central Queensland, has unearthed new insights into how the massive creature lived.
Stephen Poropat, lead researcher from Curtin University's School of Earth and Planetary Sciences, said Ann is the first sauropod dinosaur found in Australia to include most of its skull, and the first Diamantinasaurus to have its back foot preserved. "These include details of the brain case, the bones forming the back end of the skull near the jaw joint, and in the shape of the teeth ."Dr Poropat said his team's research supported previous theories that sauropods were travelling between continents in search of more balmy weather.
"The window between 100 and 95 million years ago was one of the warmest in Earth's geologically recent history, meaning that Antarctica, which was more or less where it is now, had no ice."In that climate, Antarctica was forested, and might have been an attractive habitat or pathway for wandering sauropods.""Our research suggests that Diamantinasaurus was one of the most 'primitive' titanosaurs.
