If Laurasia and Gondwanaland were recombined, they would form the supercontinent Pangea, also commonly spelled Pangaea.
Laurasia was the northern landmass and included much of modern North America, Europe, and Asia. Gondwana, also called Gondwanaland, occupied the south and included Africa, South America, Antarctica, Australia, India, and other continental fragments. Their collision brought most of Earth’s continental crust together.
The assembly of Pangaea occurred mainly during the Carboniferous and Permian periods, with the supercontinent largely complete by the late Permian. The collision closed ancient oceans and created major mountain belts, including ranges associated with the Appalachian and Variscan orogenies.
Pangaea did not remain intact. Beginning in the Triassic and Early Jurassic, it began to split into northern Laurasia and southern Gondwana as rifting opened new ocean basins. The modern continents formed through later stages of that breakup. “Pangea” is an accepted spelling variant, so the stored answer is valid.
