Answer:
The Glossopteris fossils
Explanation:
The Glossopteris fossils, otherwise called the Glossopteridales, are the ones which are viewed as the most reoccurring fossils in the majority of the land masses. It proposes that the majority of the mainlands which exist on the earth may have migrated themselves from their past positions.
This proposes the atmosphere around these specific mainlands had been fundamentally the same as, if not totally the equivalent, and that the Glossopteris had been a typical plant back in the days, notwithstanding it having the option to adjust well.
