The diagram below shows two locations where fossils of Mesosaurus have been found. Mesosaurus was a freshwater reptile that existed on Earth about 250 million years ago.

Question

Which statement best explains why these freshwater Mesosaurus fossils are found today in some rock layers in both South America and Africa?

Answer 1

The presence of Mesosaurus fossils in both South America and Africa suggests that these land masses were once connected, allowing the freshwater reptile to move freely between the two regions. This supports the theory of continental drift, where the continents have moved over millions of years due to tectonic plate movement.
