What is Laurussia?
[[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 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. 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]]. {{Continents}} {{geo-stub}} [[Category:Supercontinents]]
