Sponge Spicules in Pottery: New Data from Mali

Abstract

Until recently, the presence of sponge spicules in ancient ceramics has only been reported from South America. Current technological studies of Neolithic pottery from Sudan and Iron Age pottery from Mali provide evidence that sponge spicules are also a distinctive inclusion of some African ceramics. In this study, new data concerning the presence and quantitative variability of sponge spicules in West African Iron Age pottery from sites along the Niger River are discussed. Additionally, we discuss the potential archaeological insights offered by the study of sponge inclusions in pottery, and we consider methods for assessing whether or not these spicules were intentionally added as temper to vessels.
