Pangaea Ultima is a possible future supercontinent configuration. ... There is a concern the topic of this article may be unencyclopedic. ... Austro-Antarctica-Eurafrasia, (following the Pangaea Ultima supercontinent theory) is a possible future supercontinent that could result from a collision between Antarctica and Australia (now part of the supercontinent of Austro-Eurafrasia). ... Austro-Eurafrasia is a future supercontinent that is predicted to form when Australia collides with Eastern Asia, forming a large mountain range higher than that the Himalayas. ...

Kenorland(~2.7 Ga. Neoarchean sanukitoid cratons and new continental crust formed Kenorland. Protracted tectonic magna plume rifting occurred 2.48 to 2.45 Ga and this contributed to the Paleoproterozoic glacial events in 2.45 to 2.22 Ga. Final breakup occurred ~2.1 Ga.)
Ur(~3 Ga ago, though probably not a supercontinent; but still however, the earliest known continent. Ur, however, was probably the largest, perhaps even the only continent three billion years ago, so one can argue that Ur was a supercontinent for its time, even if it was smaller than Australia is today). Still an older rock formation now located in Greenland dates back from hadean
Vaalbara(~3.6 Ga ago. Evidence is the Yilgarn Craton, Western Australia and the world-wide Archean greenstone belts that were subsequently spread out across Gondwana and Laurasia)
Yilgarn(Zircon crystals from the Jack Hills of the Narryer Gneiss Terrane, Yilgarn craton, Western Australia and also 300 km. south point to a continental crust formation between 4.4-4.3 Ga. Evidence is the high Oxygen-18 values of 8.5 and micro-inclusions of SiO2 in these zircon crystals consistent with growth from a granitic source supracrustal material, low-temperature interactions and a liquid ocean.)

Since the definition of continent is arbitrary, the definition of supercontinent is also arbitrary (as is the definition of a subcontinent), but the term refers to a landmass containing more than one of the modern continents.
Most commonly, the term supercontinent is used to refer to a landmass consisting of all the modern continents.
Supercontinents block the flow of heat from the Earth's interior, and thus cause the asthenosphere to overheat.
