Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [1] was the vast superocean that encompassed planet Earth and surrounded the supercontinent Pangaea, the latest in a series of supercontinents in the history of Earth
There are seven continents in our world today. But 250 million years ago, those continents may have been one giant supercontinent called, Pangaea. How did it break up into the world we know today?
The supercontinent Pangaea surrounded by the superocean Panthalassa. A superocean is an ocean that surrounds a supercontinent . It is less commonly defined as any ocean larger than the current Pacific Ocean . [ 1 ]
Map of Earth during the Early Permian, around 285 million years ago, showing Central Pangean mountain range at equator. The Central Pangean Mountains were formed during the collision of Euramerica and northern Gondwana as part of the Variscan and Alleghanian orogenies, which began during the Carboniferous approximately 340 million years ago, and complete by the beginning of the Permian around ...
The Mesozoic Era [3] is the era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Periods.It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of gymnosperms such as cycads, ginkgoaceae and araucarian conifers; a hot greenhouse climate; and the tectonic break-up of Pangaea.
In contrast with Pannotia, little is known about Rodinia's configuration and geodynamic history. Paleomagnetic evidence provides some clues to the paleolatitude of individual pieces of the Earth's crust, but not to their longitude, which geologists have pieced together by comparing similar geologic features, often now widely dispersed.
In North America it shows as later phases of the Acadian orogeny. This was happening at around the Equator during the later Carboniferous, forming Pangaea with Avalonia near its centre but partially flooded by shallow sea. [14] In the Jurassic, Pangaea split into Laurasia and Gondwana, with Avalonia as part of Laurasia. [15]
