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.
Pangaea was C-shaped, with the bulk of its mass stretching between Earth's northern and southern polar regions and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.
Superocean. 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] Named global superoceans include Mirovia, which surrounded the supercontinent Rodinia, and Panthalassa, which surrounded ...
Supercontinent. The supercontinent of Pangaea with the positions of the continents at the Permian - Triassic boundary, about 250 Ma. AR=Amuria; NC= North China; SC= South China; PA= Panthalassic Ocean; PT= Paleotethys Ocean; NT= Neotethys Ocean. Orogens shown in red. Subduction zones shown in black.
Gondwana (/ ɡɒndˈwɑːnə /) [ 1 ] was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian Subcontinent. Gondwana was formed by the accretion of several cratons ...
Laurentia, the Palaeozoic core of North America and continental fragments that now make up part of Europe, collided with Baltica and Avalonia in the Caledonian orogeny c. 430–420 Mya to form Laurussia. In the Late Carboniferous Laurussia and Gondwana formed Pangaea. Siberia and Kazakhstania finally collided with Baltica in the Late Permian to ...
Tethys Ocean. First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana. The Tethys Ocean (/ ˈtiːθɪs, ˈtɛ -/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era ...
The western edge of Pangea lay at the margin of an enormous ocean, Panthalassa (lit. ' entire sea ' ), which roughly corresponds to the modern Pacific Ocean . Practically all deep-ocean crust present during the Triassic has been recycled through the subduction of oceanic plates, so very little is known about the open ocean from this time period.
