Was there only Supercontinent “Pangea”?

It was commonly thought that there is only one Supercontinent, “Pangea
But recent research conducted by the Curtin University has found two other continents on the earth plane before the Pangea.

Pangea has existed from the late Paleozoic to early Mesozoic eras on the geological time scale. About 175 million years ago, Pangea started breaking into Gondwana and Laurasia. Pangea was a supercontinent and surrounded by the ocean known as Panthalassa. Alfred Wagner gave the concept that once these continents were attached, they formed one single continent.

Alfred Wagner also proposed the scientific theory, which is known as “Continental Drift.
The continental drift concept was becoming more authentic with additional evidence. Such as,

  1. The coastline of south and north America with Africa and Europe seemingly close fit.
  2. Fossils evidence that similar age and species of fossils exist on one continent can be found on other continents.
  3. Paleomagnetic evidence.

According to a researcher from Curtin University, that there were two supercontinents before 2 billion years ago. But the exciting thing is they were geographically isolated, never joined together to form one single Supercontinent.
The lead researcher from Curtin University, Dr.Liu, said that this not the final conclusion of this research; more research needs to carry out and more data collection needed to reach the final conclusion.

One thought on “Was there only Supercontinent “Pangea”?

  1. If any continents are starting with ocean plates and subductions, all islands and continents are small to large with collision process with “irreversible development” of active water planet Earth. One model can explain one meanings of dynamic planet with ocean-water rich surface. (Y.M.)
