Nok culture iron-working and terracotta art flourishes

The Nok culture is best placed in the last half of the last millennium BCE, with iron-smelting evidence and terracotta figurines. At Taruga, iron-smelting furnaces, slag and tools were radiocarbon-dated mostly to 500–200 BCE; no stone tools were found there, indicating Nok was already a fully iron-using culture. Nok-style finds span an elongated area west and south of the Jos Plateau.
