[[Image:Caledonides EN.svg|thumb|250px|Laurussia, red lines mark the border of the 3 landmasses that make up Laurussia]]
'''Laurussia''' was a minor [[supercontinent]] which formed in the [[Devonian]] [[Period (geology)|period]]. It is often called the '''[[Old Red Sandstone]] Continent''' or '''Euramerica'''.
Laurussia included much of what is now northern [[Europe]], [[Greenland]] and [[North America]].
==Lifespan==
Laurussia formed when 3 continents Baltica, North America, and Avalonia collided with each other during the [[Silurian]]. Baltica and North America collided with each other first. Then Avalonia collided with Baltica before colliding with North America. Avalonia completely closed the [[Iapetus Ocean]] and opened the Rheic Ocean behind it.
Laurussia became part of [[Pangaea]] in the [[Permian]]. In the [[Jurassic]], when Pangaea rifted into two supercontinents, [[Gondwana]] and [[Laurasia]], Laurussia became part of Laurasia. The [[Atlantic ocean]] opened up in the middle of Laurussia, causing it to split into [[North America]] and [[Europe]].
