To support the existence of Pangaea, we can look at fossil records and how they correlate across different continents that are now separated by vast oceans. Here are three examples of fossils that support the theory of Pangaea:
1. **Glossopteris**: This genus of seed ferns provides compelling evidence for Pangaea. Fossils of Glossopteris have been found in South America, Africa, Antarctica, Australia, and India. The widespread distribution of these fossils indicates that these continents were once joined, allowing this particular plant species to thrive in a single climate zone.
2. **Mesosaurus**: This freshwater reptile lived in the Permian period, and fossils of Mesosaurus have been found in both South America and Africa. The presence of this non-marine creature in two distant continents suggests that these landmasses were once connected by land, as Mesosaurus would not have been able to swim across the open oceans that exist today.
3. **Cynognathus**: This terrestrial reptile from the Triassic period is another important piece of evidence for Pangaea. Fossils of Cynognathus have been discovered in both South America and Africa. The similarities in fossil records indicate that these landmasses were once part of a larger supercontinent, allowing for the migration and evolution of species like Cynognathus across these regions.
These fossil findings are critical to the Pangaea hypothesis as they demonstrate that organisms could not have independently evolved in vastly separated landmasses, suggesting that these continents were once aligned in close proximity. The distribution of these and other fossils thus provides significant evidence in support of the existence of Pangaea.
