1. Matching Coastlines: The coastlines of continents like South America and Africa fit together like puzzle pieces. This suggests that they were once connected and have drifted apart over time. While not a perfect fit due to erosion and tectonic activity, the similarity is striking and points to a shared past.
2. Fossil Distribution: Identical fossils of ancient plants and animals have been found on continents now separated by vast oceans. This suggests that these landmasses were once united, allowing for the migration and dispersal of these species. For example, the discovery of Mesosaurus fossils in both South America and Africa was a key piece of evidence, as this freshwater reptile could not have crossed the Atlantic Ocean.
3. Geological Formations: Similar rock formations and mountain ranges can be found on continents now separated by oceans. This suggests that these landmasses were once a continuous landmass that has been broken apart by tectonic forces. The Appalachian Mountains in North America, for instance, are a geological continuation of the Caledonian Mountains in Scotland, indicating that they were once part of the same landmass.
