Pangaea and along the adjacent margins of east Africa, Antarctica and Madagascar, new rifts were forming that would lead to the formation of the southwestern Indian Ocean that would open up in the Cretaceous. The second major phase in the break-up of Pangaea began in the Early Cretaceous (150–140 Ma), when the minor supercontinent of Gondwana separated into multiple continents (Africa, South America, India, Antarctica, and Australia). The subduction at Tethyan Trench probably caused Africa, India and Australia to move northward, causing the opening of a "South Indian Ocean". In the Early Cretaceous, Atlantica, today's South America and Africa, finally separated
Gondwana Rainforests of Australia are divided into sections for listing on the Australian National Heritage List, from north to south, as below: Gondwana Rainforests The Gondwana Rainforests of Australia, formerly known as the Central Eastern Rainforest Reserves, are the most extensive area of subtropical rainforest in the world. Collectively, the rainforests are a World Heritage Site with fifty separate reserves totalling from to Brisbane. The Gondwana Rainforests are so-named because the fossil record indicates that when Gondwana existed it was covered by rainforests containing the same kinds of species that are living today. Not all Gondwanan rainforests in Australia are located in
