Antarctica was formed by the breaking of the Gondwana supercontinent. Scientists say Antarctica used to be much farther from north and much warmer, moving to where it is now through continental drift. From 2010 to 2015, scientists collected fossils of frogs, water lilies, and shark and ray teeth, showing that these life forms used to live on Antarctica. The frog fossils were about 40 million years old. Scientists say marsupials, animals that keep their babies in pouches, could have started in South America, migrated to a warm ancient Antarctica, and gone to Australia from there.
