Question

Why was the Mesosaurus fossil one of the most convincing arguments in favor of continental drift?

a
The Mesosaurus was a water dwelling dinosaur whose fossils were found atop the Himalayan mountains.
b
The Mesosaurus fossils were tropical plant seeds found in Antarctica, suggesting Antarctica must have once been in a tropical location.
c
The fossils of this freshwater reptile were found in both South America and Africa could not have swam across the Atlantic ocean.
d
The fossils of the Mesosaurus were found in a rock layer that was older than the Mesosaurus itself.

Answer 1

The correct answer is:

c. The fossils of this freshwater reptile were found in both South America and Africa and could not have swum across the Atlantic ocean.

This finding provided strong evidence for the theory of continental drift, as it suggested that the continents were once joined together, allowing the Mesosaurus population to spread across what is now the Atlantic Ocean.
