Metatheria ago, followed by the evolution of deltatheroidian-like taxa in Asia and North America about 120-100 million years ago and then the Paleocene diversification of relatives to the crown marsupials in South America. This makes it a contemporary to some early eutherian species that have been found in the same area. The oldest metatherian fossils are found in present-day China. About 100 mya, the supercontinent Pangaea was in the process of splitting into the northern continent Laurasia and the southern continent Gondwana, with what would become China and Australia already separated by the Tethys Ocean. From there, metatherians spread westward into
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
