Wikipedia
Laurasia ( or ) was the more northern of two supercontinents (the other being Gondwana) that formed part of the Pangaea supercontinent around ( Mya). It separated from Gondwana (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split.
The name combines the names of Laurentia, the name given to the North American craton, and Eurasia. As suggested by the geologic naming, Laurasia included most of the land masses which make up today's continents of the Northern Hemisphere, chiefly Laurentia, Baltica, Siberia, Kazakhstania, and the North China and East China cratons.
