What best describes why fossils of the same land-dwelling species have been discovered in both South America and Africa?

South America and Africa are two continents separated by a large ocean. Scientists have found 200-million-year-old Mesosaurus fossils on both continents. What is the most likely explanation for how these fossils came to be found on both continents?

• The animals crossed a land bridge that once connected the continents.

• The fossils were brought to South America by explorers.

• The continents were both created through volcanic activity.
