Quick Summary

Laurussia, also known as Euramerica, was an ancient supercontinent that formed in the Northern Hemisphere during the Devonian Period. It was created by the union of the paleocontinents Laurentia and Baltica. This landmass included what are now North America and Eurasia, excluding the Indian subcontinent.12

Laurussia was characterized by widespread continental deserts and alluvial plains, evidenced by deposits like the Old Red Sandstone. The distribution of nonmarine fish and marine invertebrate fossils indicates that Europe, Siberia, and the Canadian Arctic islands were connected, forming the main body of Laurussia. This supercontinent later fragmented into the present-day continents of North America, Europe, and Asia approximately 66 to 30 million years ago.134

Paleogeography
The principal landmass of Laurussia was made up of present-day North America, western Europe through the Urals, and Balto-Scandinavia. Much of Laurussia lay near the paleoequator, whereas the cratons of Siberia, Kazakhstania, and most of China existed as separate continents occupying positions at high latitudes. During this time, the…
