Vaalbara

Vaalbara is theorized to be Earth's first supercontinent, beginning its formation about 3,600 million years ago, completing its formation by about 3,100 million years ago and breaking up by 2,500 million years ago. The name Vaalbara is derived from the South African Kaapvaal craton and the West Australian Pilbara craton. These cratons were combined during the time of the Vaalbara supercontinent.
