During this period, the extinct glossopterids colonised Gondwana and reached peak diversity in the Late Permian when coal-forming forests covered much of Gondwana. The period also saw the evolution of Voltziales, one of the few plant orders to survive the end-Permian extinction (57% of marine families and 83% of genera went extinct) and which ...
Because the formation of Gondwana encompassed several continents and extended from the Neoproterozoic to the early Palaeozoic, Pan-African could no longer be considered a single orogeny, [4] but rather an orogenic cycle that included the opening and closing of several large oceans and the collisions of several continental blocks.
Meanwhile, mammals slowly settled in Laurasia from Gondwana in the Triassic, the latter of which was the living area of their Permian ancestors. They split in two groups, with one returning to Gondwana (and stayed there after Pangaea split) while the other staying in Laurasia (until further descendants switched to Gondwana starting from the ...
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 ...
Gondwana fragmented as these continents drifted apart at different velocities; [9] a process which led to the opening of the Indian Ocean. [ 10 ] In the late Cretaceous approximately 100 million years ago , and subsequent to the splitting from Gondwana of conjoined Madagascar and India , the Indian plate split from Madagascar and formed Insular ...
The Gondwana sediments form a unique sequence of fluviatile rocks deposited in Permo-Carboniferous time. The Damodar and Sone river valleys and Rajmahal hills in eastern India contain a record of the Gondwana rocks. The Geological Survey of India has published the List of National Geological Monuments in India. [1] [2] [3]
Tamils are native to Tamil Nadu, Puducherry and northern and eastern Sri Lanka, but are also found in parts of Kerala, Karnataka and Andhra Pradesh, although they have a large diaspora and are also widespread throughout many countries including South Africa, Singapore, the United States of America, Canada, Fiji, Indonesia, Vietnam, Cambodia ...
The history of Sri Lanka is unique because its relevance and richness extend beyond the areas of South Asia, Southeast Asia and the Indian Ocean.The early human remains which were found on the island of Sri Lanka date back to about 38,000 years ago (Balangoda Man).
