Which fossils occurs on most landmasses in Pangaea?

The fossil of the reptile Mesosaurus is one of the most notable fossils found on multiple landmasses that were part of Pangaea. This freshwater creature is significant because its remains have been discovered in both South America and Africa, suggesting that these continents were once connected. Additionally, fossils of the plant Glossopteris, which was a seed fern, are also widespread across Pangaea's former landmasses, further supporting the theory of continental drift.
