n. A supercontinent that existed from the Jurassic to Early Tertiary after splitting from Pangea; composed of Laurentia, Baltica, Avalonia, (modern North America, Scandinavia, Greenland, Western and Central Europe); eventually fragmented into Eurasia and North America in the Tertiary with the opening of the North Atlantic Ocean.
The ancient continental land mass that is thought to have split apart to form Europe, Asia, North America, and Greenland.
Northern section of Pangaea.
The protocontinenet of the Northern Hemisphere from which the present continents have been derived by separation and continental displacement. Some geologists believe that Laurasia (and Gondwana) was derived from the supercontinent, Pangaea.
Northern super-continent of the Jurassic.
A protocontinent of the Northern Hemisphere, corresponding to Gondwana in the Southern Hemisphere, from which the present continents of the Northern Hemisphere have been derived by separation and continental displacement. The supercontinent from which both were derived is Pangea. Laurasia included most of North America, Greenland, and most of Eurasia, excluding India. The main zone of separation was in the North Atlantic, with a branch in Hudson Bay; geologic features on opposite sides of these zones are very similar.
the northern protocontinent that was derived from Pangaea. It comprised of North America, Eurasia (exclusive of India) and Greenland.
a hypothetical continent that (according to plate tectonic theory) broke up later into North America and Europe and Asia
northern portion of Pangaea, which consisted of the present day continents of Eurasia (Europe and Asia) North America
A Late Paleozoic, Northern Hemisphere continent composed of the present-day continents of North America, Greenland, Europe, and Asia.
The former supercontinent that formed in the northern hemisphere. This landmass later joined with the Gondwana to form the mighty Pangea.
Laurasia was the northern supercontinent formed after Pangaea broke up during the Jurassic period. Laurasia included what are now North America, Europe, Asia, Greenland, and Iceland.
the protocontinent of the Northern Hemisphere, a hypothetical landmass comprising North America, Europe and Asia, which according to the theory of plate techtonics began to break up into the present continents during the Cenozoic era. [AHDOS
Laurasia was a supercontinent that most recently existed as a part of the split of the Pangaean supercontinent in the late Mesozoic era. It included most of the landmasses which make up today's continents of the northern hemisphere, chiefly Laurentia (most of modern North America), Baltica, Siberia, Kazakhstania, and the North China and East China Cratons.
