Gondwana was a huge landmass that fragmented to form the current day America, Africa, Australia, India, Arabian Peninsula, Balkans, Madagascar, and Antarctica. Laurasia (), was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around 335 to 175 million years ago (Mya), the other being Gondwana. This overturn is like a conveyor belt that moves the plates of the crust. 3 to 0.

The Neo-Tethys Ocean was an eastward-gaping triangular oceanic embayment between Laurasia to the north and Gondwana to the south. In the Cretaceous (121-66 MYA), the Indian subcontinent started drifting towards Eurasia from Gondwana land and collided with Asia about 56-35 MYA (Briggs, 2003; Ali and Aitchison, 2008; Aitchison.

One fossil is the earliest known specimen of Homo sapiens found outside Africa; the other is a Neanderthal. The name of Gondwana was coined by the Austrian geologist Eduard Suess (1831–1914) after the land of the Gonds in India where tillite and coal deposits occur like those that occur on all of the southern continents. “When you look at simulations of Gondwana breaking up, the plates kind of start to move, and then India comes slowly off of Antarctica, and suddenly it just zooms across — it’s very dramatic,” Royden says.

One of the fragments—the Indian Shield, drifted approximately northward and eventually collided onto the Eurasian plate, producing the. WebThe aforementioned phenomena make it possible to conclude that this region is a giant geodynamic node formed in the northern hemisphere at the intersection of the latitudinal critical parallel (35 о) in the Eurasia and Gondwana junction zone and the meridional step of the Ural-African geoid anomaly. The Gondwana facies reflects three tectonostratigraphic stages generated by the Pangean heat anomaly. Eurasia, like Africa, suffered relatively few megafaunal extinctions in the late Pleistocene (Table 9).

This indicates that multiple subduction systems operated within the Neo-Tethys since 130 Ma, when the Indian plate separated. (2004. Within Carabini, the speciation rate was higher for wingless than winged states. As can be seen from these comparisons, the EQT was located some 3,000 km north of the Indian margin of. These were almost completely separated by the equatorial Tethys seaway, and the various segments of Laurasia and Gondwana had already started to rift apart. Other articles where Neo-Tethys Sea is discussed: Cenozoic Era: Geologic processes: The equatorially situated east–west Tethyan seaway linking the Atlantic and Pacific oceans was modified significantly in the east during the middle Eocene—about 45 million years ago—by the junction of India with Eurasia, and it was severed into two parts by the confluence of Africa, Arabia, and Eurasia.
