Rare 95-Million-Year-Old Dinosaur Skull Uncovered.

Rare 95-Million-Year-Old Dinosaur Skull Uncovered in Australia.

The first-of-its-kind find reveals how sauropods may have moved between Australia and South America during the mid-Cretaceous.

Now, the 95-million-year-old fossil is revealing insights into how dinosaurs may have traveled between continents. In a paper published last week in Royal Society Open Science, Poropat and his colleagues detail the similarities between Ann and another sauropod discovered in Argentina and described in 2016. The authors suggest these dinosaurs may have traveled between South America and Australia by crossing Antarctica during the mid-Cretaceous.

“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,” Poropat says in a statement. At that time, Australia, Antarctica, New Zealand and South America were all connected in a southern landmass known as Gondwana. “In that climate, Antarctica was forested and might have been an attractive habitat or pathway for wandering sauropods.”
