1. Matching Coastlines: The most obvious piece of evidence is the striking similarity of the coastlines of continents, particularly South America and Africa. They seem to fit together like puzzle pieces, suggesting they were once connected. This observation, while initially intriguing, lacked the scientific rigor to be conclusive.
2. Fossil Distribution: The discovery of identical fossils of ancient plants and animals on continents now separated by vast oceans was a major breakthrough. This provided strong evidence that these landmasses were once united, allowing the same species to inhabit them. The presence of Mesosaurus fossils, a freshwater reptile, in both South America and Africa was particularly significant.
