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 globetrotters, National 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.
