Ancient Iron Age African culture.
It existed on the Benue Plateau of Nigeria between about 500 BC and AD 200 and was first discovered in 1928 in the village of Nok. Artifacts having similar features were found over an area that stretched about 300 miles (480 km) east to west and 200 miles (320 km) north to south. The most characteristic of these are hollow, coil-built clay figurines of animals and stylized human beings, usually heads. Other artifacts include iron and stone tools and stone ornaments.
