Temagami Greenstone Belt was south of Laurenta, Siberia was just south of the equator east of Laurenta, and Gondwana lied mostly in the Southern Hemisphere. Subsequently, Baltica, Laurenta and microcontinent Avalonia collided in the Devonian period (416-359 million years ago) to form minor supercontinent Euramerica. This eventually started to collide with Gondwana and other landmasses to form supercontinent Pangaea 255 million years ago. In the Late Triassic period some 152 million years ago, Pangaea split into two minor supercontinents, namely Gondwana and Laurasia. The TGB represented a minor portion of western Laurasia until it divided into Eurasia and North America about 94 million
Gondwana (57% of marine families and 83% of genera went extinct) which came to dominate in the Late Permian and from whom true conifers evolved. Tall lycopods and horsetails dominated the wetlands of Gondwana in the Early Permian. Insects co-evolved with glossopterids across Gondwana and diversified with more than 200 species in 21 orders by the Late Permian, many known from South Africa and Australia. Beetles and cockroaches remained minor elements in this fauna. Tetrapod fossils from the Early Permian have only been found in Laurasia but they became common in Gondwana later during the Permian.
