Gondwanaland was a supercontinent that existed from the Neoproterozoic (about 550 million years ago) until the Carboniferous(about 320 million years ago).
It was formed by the accretion of severalcratons. Eventually, Gondwana became the largest piece of continental crust of thePaleozoic Era, covering an area of about 100,000,000 km2 (39,000,000 sq m During the Carboniferous, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pangaea) gradually broke up during the Mesozoic Era. The remnants of Gondwana make up about two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, and theIndian Subcontinent.
The formation of Gondwana beganc. 800 to 650 Ma with the East African Orogeny – the collision of India and Madagascar with East Africa – and was completed c. 600 to 530 Ma with the overlapping Brasiliano and Kuungaorogenies – the collision of South America with Africa and the addition of Australia and Antarctica, respectively.
