{List of continents}

This is a list of continents.

Past

The list is written in reverse-chronological order ("stratolithic order"). Dates are given as the approximate beginning of the formation of the supercontinent; dates in parentheses are approximate date of the fully formed supercontinent. The Notes column provides the geologic time period of the fully formed supercontinent.

List of supercontinents

Name	Ga (Billions of years ago)	Geologic time period / Notes
Zealandia	0.1-0.79
Laurasia	~0.253–~0.056	Phanerozoic > Mesozoic
Pangaea	~0.335 (0.299) –~0.173	Phanerozoic > Paleozoic > Permian
Euramerica	0.433-0.056	Was next to Gondwana.
Gondwana	~0.62–~0.132	Appeared in 550mya or the breakup of Pannotia.
Pannotia, also called Vendian	0.62–~0.555	Precambrian > Proterozoic > Neoproterozoic > Ediacaran
Avalonia	0.63–0.56
Protogondwana	1.071–0.62
Protolaurasia	1.071–0.592
Rodinia	1.071–~0.75	Precambrian > Proterozoic > Neoproterozoic > Tonian
Cimmeria	1.25–present
Baltica	1.8–present
Laurentia	1.816–present
Columbia, also called Nuna	~1.82–1.35	Precambrian > Proterozoic > Mesoproterozoic > Calymmian
Nena	1.95–0.592	Formation is 1.95 bya.
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	~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	~3.0–2.803	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	Existed when Vaalbara was formed.
Yilgarn Craton	4.27-present	Existed when Vaalbara and the Superior Craton was formed.

List of Supercontinents

Name	Millions of years in the future	Notes
Novopangaea	250	This assumes closure of the Pacific Ocean, docking of Australia with East Asia, and northward motion of Antarctica.
Pangaea Proxima	250	Africa will have met North America by this time.
Amasia	250	Continents moves north and meet near the Arctic Circle.
Aurica	250	Western Eurasia splits from Eastern Asia and moves west along with Africa. Meanwhile, Eastern Asia moves east along India and Australia.
Afro-Euraustralasia	27–215
