In 3–5 sentences, identify and describe the fossil evidence Wegener used to support the theories of continental drift and plate tectonics.(

Answer 1

Alfred Wegener supported his theory of continental drift by citing fossil evidence that indicated once-contiguous landmasses. He noted that identical fossils of the freshwater reptile Mesosaurus were found in both South America and Africa, suggesting these continents were once connected. Additionally, fossils of the plant Glossopteris were discovered across several southern continents, further supporting the idea of a supercontinent called Gondwana. Wegener posited that the distribution of these fossils could not be explained by evolution alone, but rather indicated that the continents had drifted apart over geological time.
