New long-neck dino may have embarked on transcontinental slog across Antarctica

Researchers now believe a group of massive, herbivorous, long-necked dinosaurs called sauropods were quite the globetrottersNational Geographic reports. Their tip-off? A recently discovered skull in Australia that forced them to reorganize the sauropod family tree. The nearly 100-million-year-old skull, which belongs to a new species dubbed Savannasaurus elliottorum, suggests that Australia’s sauropods descended from relatives in South America and arrived Down Under tens of millions of years after other dinosaurs on the continent. 

That means the only sensible connecting route for them would have been across an iceless Antarctica, the researchers report today in Scientific Reports.
