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.
Formed in late Cambrian, Rheic Ocean stretched between Gondwana and the microcontinent of Avalonia. Cuyania (northwest of today's Argentina) was located at low latitudes. Gondwana, already a large continent, consisted of today's South America, Africa, the Arabian Peninsula, India, eastern Australia and eastern Antarctica.
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 tracks were originally created about 621 miles apart over a thin sandstone layer of silt and mud on the former supercontinent Gondwanan, which later separated and formed the south Atlantic Ocean.

Australia separated from Gondwana 99 Ma, and initially remained warm and humid with rainforest vegetation. Inland Australia had systems of rivers and lakes with abundant wildlife. Fossil birds, platypus, frogs and snakes are present from this period. From 30 Ma there was a period of global cooling, and from 15 Ma the Antarctic ice sheet formed.
