Chilenia

Chilenia was an ancient small continent, a piece of crust that helped shape the rocks in central Chile and western Argentina. It used to lie apart from the nearby Cuyania landmass, separated by oceanic crust. About 420 to 390 million years ago, Chilenia collided with and joined Cuyania, which had already become part of Gondwana.
