Earth's Interior, Plate Tectonics, and Boundaries

How did fossils show that the continents were once joined together?

• Animal fossils such as the mesosaurus were found on one continent.

• Freshwater animal fossils were found in the nearby oceans.

• Scientists found examples of different kinds of fossils on some continents.

• Plant fossils of the same kind of fernlike plants were found on five continents.
