Itaakpa, a Late Stone Age site in southwestern Nigeria

Abstract

Itaakpa rockshelter was excavated in three short field seasons, from 1985 to 1988, during which a human maxilla and mandible were found in a context characteristic of the ceramic phase of the West African Late Stone Age (LSA). An AMS date of 2210±80 b.p. was obtained from burned palm kernels from the same level. There was no apparent stratigraphic or archaeological break between this level and the layers above, and the pottery indicates continuity of occupation; the upper part of the sequence compares well with other, more recent, sites known in the area. The dimensions of the human teeth show an affinity with those found at Shum Laka, a rockshelter in southwestern Cameroun, in an archaeological context similar to that at Itaakpa. The site is only the third to be found in Nigeria (along with Iwo Eleru and Rop Rockshelter) where human remains suitable for comparative analysis have been identified in a good stratigraphic context along with LSA artifacts.
