Pangaea came together during the Paleozoic and has been breaking up since the Mesozoic. The supercontinent was the most recent.
Why It Matters
- Pangaea formed around 300 million years ago and began to break apart around 200 million years ago.
- While Pangaea was together, there was one giant ocean called Panthalassa.
- Geological evidence exists for the continents coming together on each of these continents.
- Distribution of fossils provides evidence for the existance of Pangaea.
Fossils found across continents provides evidence for Pangaea
- There is also evidence for the supercontinent rifting apart.
