Laurussia formed when 3 continents Baltica, North America, and Avalonia collided with each other during the [[Silurian]]. Baltica and Avalonia collided with each other first in the Shelveian Phase of the Caledonian orogeny. Then Avalonia and Baltica collided with North America in the Acadian Phase of the Caledonian orogeny. This drift of Avalonia closed the [[Iapetus Ocean]] and opened the Rheic Ocean behind it.
