Pangaea A single supercontinent which came into being in late Permian times and persisted for about 40 Ma before it began to break up at the end of the Triassic Period; or, in the view of some people, which existed throughout most of the Earth's history prior to the Triassic (the matter remains unresolved). It was surrounded by the universal ocean of Panthalassa.

Pangaea a vast continental area or supercontinent comprising all the continental crust of the earth, which is postulated to have existed in late Palaeozoic and Mesozoic times before breaking up into Gondwana and Laurasia.

The name is frequently stated to have been coined by A. Wegener 1914, in Die Entstehung der Kontinente und Ozeane, but it has not been found in the 1st edition of that book (actually published in 1915); Pangäa does occur in ed. 2 (1920), but with no indication that it is a coinage.

Pangaea Name for the single supercontinent that formed about 240 million years ago, and which began to break up at the end of the Triassic period. Geologists have reconstructed existing land masses with continental shelves to form models of this supercontinent. See also Gondwanaland
