Gondwana (/ ɡ ɒ n d ˈ w ɑː n ə /) [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.
Its flood basalt mostly covers South Africa and Antarctica, but portions extend further into southern Africa and into South America, India, Australia and New Zealand. [ 3 ] Karoo-Ferrar formed just prior to the breakup of Gondwana in the Lower Jurassic epoch, about 183 million years ago; [ 4 ] this timing corresponds to the early Toarcian ...
Euramerica in the Devonian [20] Map of Earth around 405 million years ago, during the Early Devonian, showing Euramerica (centre) and Gondwana (south and east) Laurentia remained almost static near the Equator throughout the early Palaeozoic, separated from Baltica by the up to 3,000 km (1,900 mi)-wide Iapetus Ocean.

Argoland, once part of the ancient supercontinent Gondwana, was long thought to be lost. But scientists discovered it splintered apart in Southeast Asia.
The sedimentary deposition from this mountain chain, known as the Gondwana Super-fan, exceeded 100 million cubic kilometres (24 million cubic miles) or the equivalent to covering the United States with c. 10 km (6.2 mi) of sediment, lasted for 260 million years and coincided with the Cambrian explosion, the sudden radiation of animal life c ...

The border between North America and South America is at some point on the Darién Mountains watershed that divides along the Colombia–Panama border where the isthmus meets the South American continent (see Darién Gap). Virtually all atlases list Panama as a state falling entirely within North America and/or Central America. [116] [117]
