Pangea (also spelled Pangaea) was an ancient supercontinent that joined almost all of Earth’s land into one huge landmass, surrounded by a vast global ocean called Panthalassa.

Quick Scoop: What was Pangea?

  • It was a single giant continent that existed hundreds of millions of years ago, before today’s continents split apart.
  • It formed as earlier continents like Gondwana and Euramerica slowly collided and fused together through plate tectonics.
  • It began to break apart roughly 200 million years ago, eventually drifting into the continents and oceans we recognize on the map today.

When did Pangea exist?

  • Pangea was fully assembled by the early Permian Period, around 299–270 million years ago.
  • It stayed together for tens of millions of years, spanning the late Paleozoic into the early Mesozoic eras.
  • The breakup started near the end of the Triassic and into the Jurassic Period, over 200 million years ago, and continued for a long time as the continents drifted apart.

Why do scientists think Pangea was real?

Researchers don’t just “guess” Pangea; they build the picture from multiple lines of evidence:

  • The continents fit together like puzzle pieces (for example, the east coast of South America and the west coast of Africa).
  • Identical fossils of plants and animals are found on continents now separated by oceans, suggesting those lands were once connected.
  • Matching rock types and mountain ranges, such as the Appalachians and related ranges in Europe and Africa, line up when the continents are “reassembled.”
  • Measurements of plate tectonic motion show continents are still moving today, so scientists can “rewind” their positions back in time.

Why does Pangea matter today?

  • It shaped where today’s continents, mountain ranges, and oceans are located, influencing climate and ecosystems all over the planet.
  • Its formation and breakup affected evolution and migration of species, including early dinosaurs, by connecting and later isolating different regions.
  • Studying Pangea helps scientists imagine future “supercontinents,” like the hypothesized “Pangea Ultima,” that might form if plate motions continue for hundreds of millions of years.

In simple terms: Pangea was the time when Earth’s land hit “merge all continents” before slowly shattering into the world map we know now.

TL;DR: Pangea was a massive ancient supercontinent, assembled about 300 million years ago and broken apart by plate tectonics about 200 million years ago, eventually giving rise to our modern continents and oceans.
