Pangaea (sometimes spelled Pangea), the most
recent of a series of supercontinents on Earth, formed about 270 million years
ago and broke apart about 200 million years ago. At this time most of the dry
land on Earth was joined into one huge landmass that covered nearly a third of
the planet's surface. The giant ocean that surrounded the continent is known as
Panthalassa.
The movement of Earth's tectonic plates formed
Pangaea and ultimately broke it apart.
Pangaea existed during the Permian and Triassic
geological time periods, which were times of great change. The Permian mass
extinction, which wiped out an estimated 96% species about 248 million years
ago, was a major event during this time.
