Land Snail Shell Beads in the Sub-Saharan Archaeological Record: When,Where, and Why?

Shell beads are well established in the archaeological record of sub-Saharan Africa and appear as early as 75,000 BP; however, most research has focused on ostrich eggshell (OES) and various marine mollusc species. Beads made from various land snails shells (LSS), frequently described as Achatina, also appear to be widespread. Yet tracking their appearance and distribution is difficult because LSS beads are often intentionally or unintentionally lumped with OES beads, there are no directly dated examples, and bead reporting in general is highly variable in the archaeological literature. Nevertheless, Achatina and other potential cases of LSS beads are present at over 80 archaeological sites in at least eight countries, spanning the early Holocene to recent past. Here, we collate published cases and report on several more. We also present a new case from Magubike Rockshelter in southern Tanzania with the first directly dated LSS beads, which we use to illustrate methods for identifying LSS as a raw material. Despite the long history of OES bead production on the continent and the abundance of land snails available throughout the Pleistocene, LSS beads appear only in the late Holocene and are almost exclusively found in Iron Age contexts. We consider possible explanations for the late adoption of land snails as a raw material for beadmaking within the larger context of environmental, economic, and social processes in Holocene Africa. By highlighting the existence of these artifacts, we hope to facilitate more in-depth research on the timing, production, and distribution of LSS beads in African prehistory.     

A collective biography of joy in academic practice

Changing working conditions at many universities over the past decade have meant longer hours, intensified record-keeping, and more precarious employment. Despite these changes, many academics still insist that we enjoy our jobs. Our inquiry is oriented toward spaces and practices that bring us joy in our daily work and help us withstand the negative effects of working in academia. This article reports on our exploration of some moments of joy at work as part of our own academic practice. Through a feminist methodology known and developed as collective biography, we wrote individual memories of joy in our teaching, publishing, and collaborating, together at a writing retreat. As we analyzed these recalled moments, we came to realize that joy emerges through a turbulent process fueled by a cocktail of emotions. In fact, we came to understand joy as affect, with affect seen as a certain sort of excess, generated around and through sensations that might contribute to feelings such as celebration, happiness, or surprise as well as fear, anger, or embarrassment. We conclude that joy does things, that it can be transformative, and that cultivating joy in academia is part of a radical praxis.
