* Distribution: Mesosaurus fossils have been found in both South America and Africa, specifically in regions now separated by the Atlantic Ocean. This is highly unusual for a freshwater reptile, which wouldn't be able to swim across such a vast expanse of saltwater.
* Limited Range: Mesosaurus was a small, freshwater reptile with a limited range. It's unlikely that it could have independently evolved on separate continents.
* Geological Time: Mesosaurus fossils date back to the Early Permian period (around 290-270 million years ago), well before the breakup of Pangaea.
Therefore, the presence of Mesosaurus fossils on both sides of the Atlantic Ocean strongly suggests that these landmasses were once connected, forming a single supercontinent, which we now know as Pangaea.
This evidence, along with other fossil discoveries and geological data, provides compelling support for the theory of continental drift and the past existence of Pangaea.
