Amazing Facts About Earth:

Pangaea was not the beginning position of the land on Earth, but one of as many as six lost worlds that have come and gone. Pangea was preceded by Pannotia about 550-650 million years ago and by Rhodinia around 1.8 billion years ago. Before them, at intervals of roughly 500 million years, Nuna, Kenorland, and Ur existed and then broke up.
