Animation of the break-up of the supercontinent Pangaea and the subsequent drift of its constituents, from the Early Triassic to recent (250 Ma to 0).. This is a list of paleocontinents, significant landmasses that have been proposed to exist in the geological past.
Laurasia and Gondwana were equal in size but had distinct geological histories. Gondwana was assembled before the formation of Pangaea, but the assembly of Laurasia occurred during and after the formation of the supercontinent. These differences resulted in different patterns of basin formation and transport of sediments.
Gondwana formed part of Pangaea for c. 150 Ma [31] Gondwana and Laurasia formed the Pangaea supercontinent during the Carboniferous. Pangaea began to break up in the Mid-Jurassic when the Central Atlantic opened. [32] In the western end of Pangaea, the collision between Gondwana and Laurasia closed the Rheic and Paleo-Tethys oceans.
Pangaea straddled the equator and extended toward the poles, with a corresponding effect on ocean currents in the single great ocean (Panthalassa, the universal sea), and the Paleo-Tethys Ocean, a large ocean that was between Asia and Gondwana. The Cimmeria continent rifted away from Gondwana and drifted north to Laurasia, causing the Paleo ...
Comparison of the paleomagnetic poles of Patagonia and Gondwana from the Devonian to Permian periods allows for the separation of the two landmasses by up to 1000 kilometres; [4] however, though such a separation is permitted by the evidence, it is not required in order to explain differences in the pole positions.

First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana.. The Tethys Ocean (/ ˈ t iː θ ɪ s, ˈ t ɛ-/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early-mid Cenozoic Era.
The vast supercontinent of Pangaea dominated the globe during the Triassic, but in the latest Triassic and Early Jurassic it began to gradually rift into two separate landmasses: Laurasia to the north and Gondwana to the south. The global climate during the Triassic was mostly hot and dry, [12] with deserts spanning much of Pangaea's interior ...
