<P> Gondwana ( / ɡɒndˈwɑːnə / ) , or 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 several cratons . Eventually , Gondwana became the largest piece of continental crust of the Paleozoic Era , covering an area of about 100,000,000 km ( 39,000,000 sq mi ) . During the Carboniferous , it merged with Euramerica 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 the Indian Subcontinent . </P>
