Pannotia
Pannotia was a supercontinent firstly described by Dalziel in 1997 which existed from about six hundred million years ago to about five hundred forty million years ago.
About 750 million years ago, the previous supercontinent Rodinia rifted apart into three continents:
Protolaurasia rotated southwards towards the south pole. Protogondwana rotated counterclockwise. Congo came between Protogondwana and Protolaurasia about six hundred million years ago. This formed Pannotia.
Pannotia was short-lived. The collisions which formed Pannotia were glancing collisions, and the continents composing Pannotia already had active rifting. By about five hundred forty million years ago, or only about sixty million years after Pannotia formed, Pannotia disintegrated into four continents:
