when did pangea break up
Pangaea did not break up in a single moment; it started rifting apart around 200 million years ago and continued splitting into today’s continents over tens of millions of years.
Quick Scoop: When did Pangea break up?
The short, straight answer
- The breakup of Pangea began near the end of the Triassic and start of the Jurassic, about 200–195 million years ago.
- The process continued in stages through the Jurassic, Cretaceous, and early Cenozoic, with different chunks separating at different times.
Key stages of the breakup
- About 200–195 million years ago: Initial rifting starts and the early Atlantic Ocean begins to open as Pangea cracks.
- 195–170 million years ago: Major early phase of breakup; Gondwana (future Africa, South America, Antarctica, India, Australia) separates from Laurasia (future North America and Eurasia).
- Around 150–140 million years ago: Gondwana itself begins to fragment into separate southern continents (Africa, South America, India, Antarctica, Australia).
- Around 60–55 million years ago: Final big phase; North America fully separates from Eurasia, opening the Norwegian Sea and further enlarging the Atlantic.

| Time (million years ago) | What was happening? |
|---|---|
| ~200–195 Ma | Pangea starts to break; early Atlantic begins opening at the Triassic–Jurassic boundary. | [5][1][3]
| 195–170 Ma | First major breakup phase; Gondwana splits from Laurasia. | [1][3]
| 150–140 Ma | Gondwana breaks into several southern continents. | [3]
| ~60–55 Ma | Laurasia splits; North America pulls away from Eurasia, opening the Norwegian Sea. | [1][3]
Why it’s a “range,” not a date
Geologists talk about “when did Pangea break up” as a multi-step story because:
- Different parts of the supercontinent rifted at different times, so there is no single calendar date for the breakup.
- Plate tectonics operates over tens of millions of years, so “about 200 million years ago” is already a simplified way to describe a long, gradual process.
If you just need a one-line takeaway:
Pangea started breaking up about 200 million years ago and took more than 100 million years to fragment into the continents we recognize today.
TL;DR: When people ask “when did Pangea break up,” the common textbook answer is that the breakup began roughly 200 million years ago, with the process unfolding in major phases between about 195 and 60 million years ago.
