Laurasia The northern continental mass produced in the early Mesozoic by the initial rifting of Pangaea along the line of the northern Atlantic Ocean and the Tethys Sea. Laurasia included what was to become North America, Greenland, Europe, Asia, and Malesia east to Sulawesi, while the large, southern continental mass (called Gondwana) was later to divide into South America, Africa, India, Australasia, Malesia east of Sulawesi, and Antarctica. Fossil evidence indicates that the Laurasian floral assemblage included many species of tropical plants that were incorporated into sediments to form the extensive coal measures that are mined throughout Europe and the eastern USA.

Laurasia a vast continental area believed to have existed in the northern hemisphere and to have resulted from the break-up of Pangaea in Mesozoic times. It comprised the present North America, Greenland, Europe, and most of Asia north of the Himalayas.
