List of Supercontinents
Name Ga
(Billions of years ago)
Laurasia ~0.253–~0.056
Pangaea ~0.335–~0.173
Euramerica 0.433-0.056
Gondwana ~0.62–~0.132
Pannotia, also called Vendian 0.62–~0.555
Avalonia 0.63-0.056
Protogondwana 1.071-0.62
Protolaurasia 1.071–0.592
Rodinia 1.071–~0.75
Cimmeria 1.25–present
Baltica 1.8-present
Laurentia 1.816-present
Columbia, also called Nuna ~1.82–1.35[1]
Nena 1.95-0.592
Atlantica 2.11-0.114 Protracted tectonic magma plume rifting occurred 1.31 Ga. Final breakup occurred ~114 Ma.
India (continent) 2.525-present
Siberia (continent) 2.695-present
Sclavia 2.665-2.33 Kenorland is a "one-piece" alternative to Superia, Vaalbara, and Sclavia.
Kenorland/Arctica ~2.72–2.1 Neoarchean sanukitoid cratons and new continental crust formed Kenorland. Protracted tectonic magma plume rifting occurred 2.48 to 2.4 Ga and this contributed to the Paleoproterozoic glacial events in 2.4 to 2.22 Ga. Final breakup occurred ~2.1 Ga.
Ur ~3.1-2.803 Classified as the earliest known landmass, Ur was a continent that existed three billion years ago. While probably not a supercontinent, one can argue that Ur was a supercontinent for its time as it was possibly the only continent on Earth, even if it was smaller than Australia is today. Still, an older rock formation now in Greenland dates back from Hadean times.
Congo (continent) (Protoafrica) 3.6-present This former continent thought to be parental to the São Francisco craton, Congo craton and the Central Africa.
Vaalbara ~3.6-2.803 Possibly the first supercontinent
Superior craton 4.031-present

Present day

List of Supercontinents

America ~-15 Myr to +150 Myr
Eurasia ~-253 Myr to ~+215 Myr If not considered a part of Afro-Eurasia
