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.
Pangaea formed during the closure of the Rheic Ocean 330 Mya (early Carboniferous) (view centred on 30°S,30°E) The subduction of the Iapetus Ocean resulted in the first contact between Laurussia and Gondwana in the Late Devonian and terminated in full collision or the Variscan orogeny in the early Carboniferous (340 Mya).

Location of the Hercynian-Alleghenian mountain belts in the middle of the Carboniferous period.Present day coastlines are indicated in grey for reference. [1]The Variscan orogeny, or Hercynian orogeny, was a geologic mountain-building event caused by Late Paleozoic continental collision between Euramerica (Laurussia) and Gondwana to form the supercontinent of Pangaea.
Pannotia was centred on the South Pole, hence its name. Pannotia (from Greek: pan-, "all", -nótos, "south"; meaning "all southern land"), also known as the Vendian supercontinent, Greater Gondwana, and the Pan-African supercontinent, was a relatively short-lived Neoproterozoic supercontinent that formed at the end of the Precambrian during the Pan-African orogeny (650–500 Ma), during the ...
The South Polar region of the Cretaceous comprised the continent of East Gondwana–modern day Australia, Zealandia, and Antarctica–a product of the break-up of Gondwana in the Cretaceous Period. The southern region, during this time, was much warmer than it is today, ranging from perhaps 4–8 °C (39–46 °F) in the latest Cretaceous ...
Muskingum (also known as Conchake) was a Wyandot village in southeastern Ohio from 1747 to 1755. [3]: 288 It was an important trade center in the early 1750s, until it was devastated by smallpox in the winter of 1752.

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 ...
