Afro-Eurasia largest present part of the supercontinent cycle. 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. This impacted southern Asia around 50 million years ago and began the formation of the Himalayas.
Supercontinent Neoarchean age broke off at ~2480 and and portions of them later collided to form Nuna (Northern Europe North America) (). Nuna continued to develop during the Mesoproterozoic, primarily by lateral accretion of juvenile arcs, and in Nuna collided with other land masses, forming Rodinia. Between ~825 and Rodinia broke apart. However, before completely breaking up, some fragments of Rodinia had already come together to form Gondwana (also known as Gondwanaland) by . Pangaea formed by through the collision of Gondwana, Laurasia (Laurentia and Baltica), and Siberia. The second model (Kenorland-Arctica) is based on both palaeomagnetic and geological evidence and
