The Nok culture is dated between 900 BC to 200 AD.
The first Nok head was found accidentally at Jemma about 140 kilometers away from Jos, in the current Plateau State of Nigeria. It was found by Bernard Fagg in May 1944. The Nok collection is predominantly terracotta. Nok artefacts had a variety of religious and cultural uses, including everyday use on farms as scare crows.
The Nok culture appears to be the first that gives evidence of iron smelting in Nigeria, and they are generally naturalistic in nature.
