A slightly curved iron disc (SF 09-172). It was found positioned upright among a carefully placed set of objects in what archaeologists interpret as a shrine feature in a metallurgical workshop. A large iron spike (SF 09-174) and an iron bangle (SF 09-173) sat next to it. The disc shows signs of corrosion by rusting. Its function is unknown, though it may be a tool preform. The disc shows signs of corrosion by rusting. Scale in cm. Width: 10.7 cm. Weight: 89.8 g. Site Ngre Kataa. 10 June 2009.
A photo scale has been placed next to a partial elephant ivory tusk, which rests insitu against an anvil stone (GS 09-32) in an area (mound 6) that archaeologists interpret as a metallurgical workshop. Several smaller stones surround the cluster. This group of objects was found adjacent to and at approximately the same depth as a series of other artifact clusters (A-D) that archaeologists interpret as a large shrine feature which capped stratified deposits associated with metalworking activities. The tusk was friable and poorly preserved, but had visible Schreger Lines diagnostic of elephant ivory. Photo scale marked in 5 cm increments. North is top of photo. Site Ngre Kataa. 10 June 2009.
