A view in cross-section of a friable ivory tusk found in association with an anvil stone (GS 09-32) in an area (mound 6) that archaeologists interpret as a metallurgical workshop. A semicircular portion of the tusk can be seen encased in dirt. Though poorly preserved, Schreger Lines diagnostic of elephant ivory were observed in the specimen. Scale in cm. Site Ngre Kataa. 11 June 2009.
Archaeologist Ben Nutor uses a trowel to scrape soil from around a cluster of objects that archaeologists interpret as a shrine feature (cluster A) in a metallurgical workshop (mound 6). An orange flag marks the location of an iron bangle (SF 08-140), the first of four that were found surrounding the large pottery bowl (NK 08-522) seen partially exposed in front of Nutor. An iron headpan used to carry dirt for screening sits nearby. Site Ngre Kataa. 9 July 2008.
