Pangaea Breaks Apart
On the timeline · around Early–Middle Jurassic, ~200–170 million years ago · The Jurassic
What happened
During the Jurassic, the supercontinent Pangaea broke apart, opening new seaways and separating the land into drifting continents. The climate grew warmer and wetter, and lush vegetation spread across the world.
Why it matters
The breakup created varied new habitats and isolated dinosaur populations, driving them to evolve into an extraordinary range of forms — including the largest animals ever to walk the Earth.
