Early Nigerian history relates to the period of history in Nigeria prior to the common era. Recent archaeological research has shown〔Shaw, T. 1969. The Late Stone Age in the Nigerian forest. Actes 1e Colloque International d’Archéologie Africaine, Fort Lamy, pp. 364–73〕 that people were already living in Nigeria (specifically the Iwo-Eleru) as early as 11,000 BC and perhaps earlier at Ugwuelle-Uturu (Okigwe) in south-eastern Nigeria.〔Shaw, T.& Daniells, S. G. H. 1984. ''Excavations At Iwo-Eleru, Ondo State, Nigeria''. West African Journal of Archsmelting furnaces at Taruga dating from the 4th century BC provide the oldest evidence of metalworking in aeology. Vol.14〕 Microlithic and ceramic industries were developed by savanna pastoralists from at least the 4th millennium BC and were continued by subsequent agricultural communities. The Efik/Ibibio/Annang Efik, Ibibio, and Annang people of single ancestor of the coastal southeastern Nigeria are known to have lived in the area several thousands of years before Christ. ==Iron Age== Kainji Dam excavations revealed ironworking by the 2nd century BC. The transition from Neolithic times to the Iron Age apparently was achieved without intermediate bronze production. Others suggest the technology moved west from the Nile Valley, although the Iron Age in the Niger River valley and the forest region appears to predate the introduction of metallurgy in the upper savanna by more than 800 years.
