The supercontinent of Pangea was an agglomeration of all the existing continents, brought together by tectonic forces around 335 million years ago, and eventually pulled apart by those same forces 160 million years later.
Its existence was first theorised by Alfred Wegener, the originator of the scientific theory of continental drift, in his 1912 publication The Origin of Continents (Die Entstehung der Kontinente). It was later proven by both geologists and paleontologists, with evidence to support the hypothesis being found in the magnetic resonance of rocks in various continents, and also by the distribution of fossils demonstrating that a land connection must have existed.
