Afro-Eurasia instance of supercontinent
Afro-Eurasia (also Afroeurasia, Eurafrasia or the Old World) is a landmass comprising the continents of Africa, Asia, and Europe. The terms are compound words of the names of its constituent parts. Its mainland is the largest and most populous contiguous landmass on Earth.
Afro-Eurasia encompasses 84,980,532 square kilometres (32,811,167 sq mi), 57% of the world's land area, and has a population of approximately 6.7 billion people, roughly 86% of the world population.Past
The oldest part of Afro-Eurasia is probably the Kaapvaal Craton, which together with Madagascar and parts of India and western Australia formed part of the first supercontinent Vaalbara or Ur around 3 billion years ago. It has made up parts of every supercontinent since. At the breakup of Pangaea around 200 million years ago, the North American and Eurasian Plates together formed Laurasia while the African Plate remained in Gondwana, from which the Indian Plate split off. Upon impact with the Eurasian Plate, the Indian Plate created southern Asia around 50 million years ago and began the formation of the Himalayas. Around the same time, the Indian Plate also fused with the Australian Plate.
The Arabian Plate broke off of Africa around 30 million years ago and impacted the Iranian Plate between 19 and 12 million years ago during the Miocene, ultimately forming the Alborz and Zagros chains of Iranian Plate. After this initial connection of Afro-Eurasia, the Betic corridor along the Gibraltar Arc closed a little less than 6 million years ago in the Messinian, fusing northwest Africa and Iberia together. This led to the nearly complete desiccation of the Mediterranean Basin, the Messinian salinity crisis. Eurasia and Africa were then again separated with the Zanclean Flood around 5.33 million years ago refilled the Mediterranean Sea through the Strait of Gibraltar.
