Fossils of the fern Glossopteris have been found in the continents of South America, Africa, Asia, and Antarctica. The seeds of this fern were too small to be dispersed by wind. Which is best indicated by the presence of Glossopteris fossils on these continents?
Glossopteris was versatile enough to adapt to all climates. The landmasses were joined together in pre-historic times. Fossils were much better preserved in the southern continents. The northern climate regions were not suitable for plant growth.
