Mesosaurus fossils in both Africa and South America can be explained by the theory of continental drift. It is believed that during the Permian period, these two continents were part of a single supercontinent known as Pangaea. Mesosaurus was a freshwater reptile that likely lived in shallow coastal waters, and its fossils have been found in both continents because these areas were once connected and shared a similar environment. As Pangaea began to break apart, Mesosaurus populations became isolated on the separate landmasses, leading to the distribution of their fossils in both Africa and South America. This evidence of Mesosaurus fossils in multiple locations is one of the key pieces of evidence supporting the theory of continental drift.
