Eduard Suess first proposed the existence of these things to explain marine transgressions in his textbook The Face of the Earth. J. J. Rogers used evidence from the Kaapvaal region to propose an early one of these objects called Ur. A cycle named for these objects is complemented by the Wilson cycle, and models the periodic closing and opening of the Earth's oceanic (*) basins; that cycle proposes that these objects are created and destroyed every 500 million years. The largest one of these structures, which contained most of the Earth's cratons, was surrounded by Panthalassa and had a name coined by Alfred Wegener. Laurasia and Gondwanaland are examples of, for 10 points, what extraordinarily large kind of landmass that includes Pangaea?
