100 million years AP

After 10 million years of global warming, the antarctic biota has gradually recovered its biodiversity, starting to reach the biodiversity peaks of the late Lentocene and the early Biancocene.
Biomes are well diversified, but the sea currents together with the increase of temperatures are gradually modifying the biotic composition. For the first time, the South American warm current is dwindling, giving rise to a hotter and drier climate in northern areas. Possibly for the first time in the entire Cenozoic, Antarctica has developed monsoon and xeric shrublands, typical of tropical environments. It was never this hot since the Mesozoic era.
The continent is truly being reborn.
