What are facts that proves the Pangaea existed?

Answer 1

Here are some pieces of evidence to prove that Pangaea did exist:

1) Fossils of the same species of dinosaurs were discovered on different continents, and as these dinosaurs could not have swam across the oceans, the must have walked from one continent to another, therefore, Pangaea existed.

2) The coasts of continents (e.g. the east coast of South America and the west coast of Africa) could be joined/fitted together almost nicely, like pieces of jigsaw puzzles.

3) Theories of continental drift and plate tectonics (which causes earthquakes...) evidently proves that the continents drifted apart.

4) The continents are still drifting apart very slowly and the oceans are still expanding up till today.

5) Paleozoic glacial deposits have been found on the continents forming Gondwanaland (Africa, Antarctica, South America, Australia/Oceania) and there were glacial striations left behind on rocks in this area.

6) Mountain belts/chains on different continents have quite similar rocks and structures and many more evidences suggests Pangaea existed.

Answer 2

Fossil evidence of similar species found on multiple continents, matching geological formations across different continents, and the fit of the continents' Coastlines all provide evidence that supports the theory of Pangaea's existence. Additionally, paleoclimatic data from rock formations and glacial deposits also suggest that the continents were once joined together.
