The largest living thing on the interior continent is a small, almost microscopic species of mosquito. Penguins, auks, and terns live on the ice caps on the fringes of the continent. The highest mountain is the Vinson Massif, at 16,066 feet. Antarctica was originally a part of Pangea. 50 million years ago it was a temperate continent near where modern Austrailia is today. This is why dozens of species of dinosaur have been discovered here.
