Wegener used various types of fossil evidence to support his theories of continental drift and plate tectonics. One type of fossil evidence he relied on was the presence of similar fossils on different continents that were separated by vast oceans. For example, he found identical fossils of the ancient reptile Mesosaurus in both South America and Africa. Wegener argued that this indicated that these two continents were once connected and later drifted apart. He also used fossil evidence of ancient plants and animals found in Antarctica, which he believed was once part of a larger landmass called Gondwana. Overall, Wegener's use of fossil evidence provided crucial support to his theories of continental drift and plate tectonics.
