Does the case of mesosaurus by itself the theory why or why not?

The case of Mesosaurus does support the theory of continental drift, particularly in the context of plate tectonics. This freshwater reptile's fossils were found in both South America and Africa, which are now separated by the Atlantic Ocean. The presence of such a species in these two distant locations suggests that the continents were once joined, allowing Mesosaurus to inhabit both regions. Thus, it provides evidence against the idea that these continents have always been in their current positions.
