The most recent supercontinent to incorporate all of Earth’s major—and perhaps best-known—landmasses was Pangea. Pangea began to fragment about 185 Ma and is still dispersing today. Laurasia se dividió posteriormente en Eurasia y Norteamérica . Mesozoic. The northward drift of the Lhasa block of southern Tibet, from northern Gondwana to the southern margin of Eurasia, occurred during the Jurassic (Li et al. England), as well as figure two more from the latter. Here, we propose a new hypothesis for the historical aspects of the neobatrachian evolution with a formal biogeographical analysis. These two regions were separated by Tethys, a tropical east-west seaway. The assembly of Gondwana began immediately following the break-up of Rodinia in Late Proterozoic times. The Tethyan evolution may be simplified as many continents rifting away from Gondwana and then continuously drifting towards the Eurasia, finally colliding and accreting onto the southern Eurasia.

It was made up of what are now Africa, South America, Antarctica, Australia, and the Indian subcontinent. Here, we study the paleolatitudinal drift history of the Lhasa terrane of southern Tibet that migrated from the northern Gondwana to the southern Eurasian margin between late Triassic and early Cretaceous time. Ants were scarce compared to other insects, until flowering plants began to blossom and produce flowers and fruits. India eventually collided with Eurasia approximately 55 million years ago, forming the Himalayan mountains, whereas the northward-moving Australian plate began its collision along the southern margin of Southeast Asia. The Mesozoic plate tectonic and paleogeographic history of Gondwana had a profound effect on the distribution of terrestrial vertebrates. Several plates drifted away from Gondwana and docked to Eurasia, during Triassic–Middle Jurassic times. WebZealandia was formerly part of Gondwana. Tectonic reconstructions of the initial breakup of Gondwana support a two-plate model: West Gondwana (South America and Africa) and East Gondwana (Antarctica, Australia, New Zealand, the Indian subcontinent, and Madagascar) (Eagles and König, 2008) (Fig. WebBy this definition the landmass formed by present-day Africa and Eurasia could be considered a supercontinent.

In geology, a supercontinent is the assembly of most or all of Earth 's continental blocks or cratons to form a single large landmass. Carboniferous-Permian: Another major glaciation took place during the late Carboniferous and early Permian. epsl. The Indian landmass breaks away from the Antarctica-Australia landmass. X. The 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 (35о) in the Eurasia and Gondwana junction zone and the meridional step of the Ural- African geoid anomaly.
