Continental assembly and uplift also meant increasingly arid land climates, favoring the evolution of amniote animals and seed plants, whose eggs and seeds were better adapted to dry climates. [40] The early drying trend was most pronounced in western Pangaea, which became a center of the evolution and geographical spread of amniotes.
In geology, a supercontinent is the assembly of most or all of Earth's continental blocks or cratons to form a single large landmass. [ 1 ] [ 2 ] [ 3 ] However, some geologists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. [ 4 ]
The supercontinent will be encircled by a global ocean, the Neopanthalassan Ocean (meaning "new" Panthalassan Ocean), [7] which encircles half the Earth. [9] The Earth is expected to have a hothouse climate with an average global temperature of 28 °C (82 °F). [7] The only areas likely to be habitable for land mammals are those closest to the ...
The formation of a new “supercontinent” could wipe out humans and all other mammals still alive in 250 million years, researchers have predicted.
Like most breakups, the separation of continents is not a quick and painless process.. Take the supercontinent Gondwana, for example. Some 180 million years ago, the landmass separated from what ...

Map of Pangaea with modern continental outlines. The supercontinent cycle is the quasi-periodic aggregation and dispersal of Earth's continental crust.There are varying opinions as to whether the amount of continental crust is increasing, decreasing, or staying about the same, but it is agreed that the Earth's crust is constantly being reconfigured.
