Basin from the Cradle of humankind

These one of a kind basins are made from the 3 billion year old rocks from the Cradle of Humankind in Johannesburg, which consist mainly of Dolomitic bedrock.

The Cradle of Humankind is a paleoanthropological site and is located about 50 km northwest of Johannesburg, South Africa, in the Gauteng province. Declared a World Heritage Site by UNESCO in 1999, the site is home to the largest concentration of human ancestral remains anywhere in the world.
