The flora, glossopteris of the south
grew in a cold, wet climate, while that of the north existed under warm
conditions. Based on the sheer number of leaf fossils found and the fact that
the plants grew in a temperate climate at middle to high latitudes, therefore,
the continent before has a temperate climate, wet to warm climate.
fossils tell us that the early positions of the continents were once combined
or amalgamated into a super continent---the Pangaea. The Glossopteridales
turn out in the Southern Hemisphere around 298.9 million
years ago, the beginning of the Permian Period.
