Laurasia (/ l ɔː ˈ r eɪ ʒ ə,-ʃ i ə /) was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around ), the other being Gondwana.It separated from Gondwana (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split and finally broke apart with the opening of the North Atlantic Ocean c. 56 …

Pangaea or Pangea (/ p æ n ˈ dʒ iː. ə /) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic.

La Laurasia ou Laurasie est un supercontinent qui se sépara du reste de la Pangée (appelé dès lors Gondwana) durant le Mésozoïque.La Laurasia se divise à son tour en Eurasie et Amérique du Nord il y a environ 65 millions d'années, avec l'ouverture de l'Atlantique nord.. Son nom provient de l'association des zones géographiques « Laurentides » et « Asie ».

Laurasia (zusammengesetzt aus Laurentia und Asia, auch Laurasien) war die nördliche der beiden großen Landmassen, in die der Superkontinent Pangaea im Mesozoikum zerbrach. Der südliche Kontinent, der während dieser Trennung erneut entstand, wird Gondwana genannt. Laurasia bestand im Wesentlichen aus den paläozoischen „Nordkontinenten“ Laurentia, Baltica, Sibiria …

The Americas (or America) are lands in the Western Hemisphere that are also known as the New World.Comprising the continents of North America and South America, along with their associated islands, they cover 8.3% of the Earth's total surface area (28.4% of its land area).. Most people consider the countries in Central America to be part of North America instead of South …
