what do the glossopteris fossils tell us about the early positions of the continents?

Sagot :

The Glossopteris arose in the Southern Hemisphere around the beginning of the Permian Period (298.9 million years ago). Their distribution across several, now detached, landmasses led Eduard Suess, amongst others, to propose that the southern continents were once amalgamated into a single supercontinent—Pangaea.   The glossopteris fossils tell us that the early positions of the continents were once combined or amalgamated into a super continent---the Pangaea. The Glossopteris turn out in the Southern Hemisphere around 298.9 million years ago, the beginning of the Permian Period.
