Alfred Wegener used fossil evidence extensively to support his theory of continental drift. One notable example is the discovery of the freshwater reptile Mesosaurus, which was found in both South America and Africa, suggesting these continents were once joined. Additionally, the plant Glossopteris, a seed fern, was found in regions now separated by vast oceans, including South America, Africa, Antarctica, and India, indicating these landmasses were once connected. Wegener also noted similar fossilized remains of the extinct land reptile Lystrosaurus across Antarctica, Africa, and India, reinforcing the idea of once-cohesive continental landmasses. These fossil findings highlighted the historical connections among continents, supporting the notion of continental movement over geological time.

Alfred Wegener presented compelling fossil evidence to bolster his theory of continental drift. One key example is the fossil of Mesosaurus, a freshwater reptile found in both South America and Africa, indicating that these two continents were once part of a larger landmass. He also identified the plant Glossopteris, a seed fern whose fossils were scattered across diverse regions, including South America, Africa, Antarctica, and India, suggesting these areas were formerly joined. Furthermore, Wegener highlighted the presence of the land reptile Lystrosaurus, found in fossils across Antarctica, Africa, and India, which further supported the idea of interconnected continents. Collectively, these fossil discoveries underscored the historical links between continents, providing evidence for their movement over geological timescales.
Alfred Wegener utilized fossil evidence as a critical element in supporting his continental drift theory. A prominent example is the Mesosaurus, a freshwater reptile whose fossils were discovered in both South America and Africa, implying that these continents were once connected. Additionally, the seed fern Glossopteris was found in regions now separated by oceans—such as South America, Africa, Antarctica, and India—suggesting a shared landmass in the past. Wegener also pointed to fossils of Lystrosaurus, an ancient land reptile, found across Antarctica, Africa, and India, which further indicated a once-cohesive supercontinent. These fossil records highlighted the once-interconnected nature of continents, lending credence to the idea of their gradual movement over time.
Alfred Wegener's theory of continental drift was strongly supported by fossil evidence that highlighted the connections between distant continents. For instance, fossils of the freshwater reptile Mesosaurus were found in both South America and Africa, leading to the conclusion that these landmasses were once joined. He also discovered fossils of the plant Glossopteris, which appeared across several continents, including South America, Africa, Antarctica, and India, hinting at a common land connection in their ancient past. Additionally, the existence of Lystrosaurus fossils in Antarctica, Africa, and India provided further evidence of this link between the continents. These findings collectively illustrated how continents were once part of a larger structure, reinforcing the idea of their movement through time.
Alfred Wegener presented a compelling case for continental drift through various fossil discoveries that indicated historical links between continents. One striking example is the freshwater reptile Mesosaurus, whose fossils were unearthed on both South American and African shores, suggesting a shared landmass in ancient times. Similarly, the presence of the plant Glossopteris, found in regions as far apart as South America, Africa, Antarctica, and India, pointed to a once-unified ecological environment. Furthermore, fossils of the land reptile Lystrosaurus, which appeared across Antarctica, Africa, and India, reinforced the notion of connected landmasses. Collectively, these fossil finds underscored the theory that continents have drifted apart over geological time, highlighting their interconnected origins.
Alfred Wegener's theory of continental drift is notably supported by fossil evidence that reveals strong connections among separated continents. For example, the discovery of the fossilized remains of Mesosaurus—a freshwater reptile—on both South American and African coasts suggests that these regions were once part of a single landmass. Similarly, fossils of Glossopteris, a prehistoric plant, have been found on different continents, including South America, Africa, Antarctica, and India, indicating they were once linked. Additionally, the land reptile Lystrosaurus has been discovered in fossil form across Antarctica, Africa, and India, further emphasizing the idea of a formerly united supercontinent. Together, these fossil discoveries provide vital insights into the historical relationships between continents, supporting the concept of their gradual separation over time.
