General Info




Where: Earth





When: Over 200 million years ago.





Why: Tectonic Plates moved and split the supercontinent that soon moved to thier present day positions.




(movment of the continents, right)

Impact On Environment

When the continents split the animals to rome on.

Some land moved near to the Equator and got warmer. Or they, like Antarctica, moved to the bottem of the earth an got colder. So where ever parts of the land went plants and animals had to adapt.

Clues About Pangaea

Fossils of plants and animals such as, Kannemeyerid, Mesosaurus, Labyrinthodont, (prehistoric animals) and the Glossoptelis (prehistoric plant) found on many different continents. Also mounten ranges that match up in age and substance are on different continents. Lastly the continents look like they fit together.

Alfred Wegener (1880-1930)

Alfred Wegener was a German mederologist. He discovered Pangaea and anounced it in 1912. Wegener beleved that the super continent existed 225 million years ago and broke apart 200 million years ago. They slowly moved to their present day positions. He cut out all the continents and put them together like a jiggsaw puzzle. Other scientists refused the idea, but soon agreed.
