Here, we show that after the continental collisions that led to the formation of Pangaea, plate convergence continued in a large, wedge-shaped oceanic tract. We suggest that plate strain at the periphery of the supercontinent eventually resulted in self-subduction of the Pangaean global plate, ...
Pangaea (redirected fromPangaean) Thesaurus Encyclopedia Related to Pangaean:Pangea,Pangea supercontinent Pangaea Pan·gae·a alsoPan·ge·a(păn-jē′ə) n. A supercontinent that included all the world's landmasses in the late Paleozoic and, according to the theory of plate tectonics, subsequen...
Its suture extends over 10,000 km from Mexico to Turkey, and its closure assembled the greater part of Pangaea with the formation of the vast Variscan–Alleghanian–Ouachita orogen. The evolution of the Rheic Ocean is consequently central not only to the history of the Palaeozoic, but also ...
These revealed that Selaginella originated on Euramerica around 383Ma in the Devonian period, while its peak diversification began with the formation of Pangea. The divergence of the two main species‐rich Selaginella lineages occurred approximately 318Ma on the supercontinent. The major divergences ...
This is because the process offormation for igneousandmetamorphic rocksinvolves heat or pressure so that fossils would be completely erased. These are the rocks that can incorporate bones, shells, and exoskeletons from living organisms such as shells that are compacted sea creatures. ...

The climate for a highly idealized geographic representation of the megacontinent of Pangaea, corresponding to the period 250-200 m.y. ago, is explored using a low-resolution atmospheric general circulation model that is coupled to a static mixed layer ocean of constant depth, with a provision ...
