BONUS: What is a Glossopteris and how was it important in discussing continental drift and Wegner's theory of Pangaea
A Glossopteris is a fern (plant) and its fossils were found on different continents and it became clear that these fossils could not travel through water or be moved through water so Wegner felt this was evidence to prove that the continents were together at one point and must have shared the same environment in order for the fern to survive.
