New Discovery Suggests Antarctica Once Had Warm Rainforest
新发现表明南极洲曾经是热带雨林


Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area was very different in the past.


The evidence was found inside a piece of Earth sediment collected by researchers from under the seafloor off the coast of Antarctica. In the sediment, they found forest soil estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals.
