Alfred Wegener collected diverse pieces of evidence to support his theory, including geological “fit” and fossil evidence. Geological “fit” evidence is the matching of large-scale geological features on different continents. Another important piece of evidence in the Continental Drift theory is the fossil relevance. There are various examples of fossils found on separate continents and in no other regions. This indicates that these continents had to be once joined together. Possibly the most important fossil evidence found is the plant, Glossopteris.
