Ostrich eggshell (OES) beads are a common feature of Later Stone Age (LSA) archaeology throughout eastern and southern Africa and have the potential to inform on site use, cultural diversity, social networks, and site formation. However, too often OES bead assemblages have not been recorded or studied in the necessary detail to make meaningful contributions to these important questions. In this respect, and to aid future research focusing on the African LSA, OES and OES beads must be discussed in detail, beginning with a background to ostriches and their eggs and commenting on why OES is an important raw material. Then, one should consider OES beads in detail, specifically, the manufacturing process, the social context in which they were made, and how they may have been used in the past. Subsequently, the focus should be on how OES bead assemblages are analyzed, as well as archaeometric approaches to studying OES bead residues and OES bead provenance. The potential insights gained from these diverse and multidisciplinary analytical approaches, especially when combined, are then highlighted through discussing trends in OES bead research from African LSA contexts. These trends include the contribution of OES beads to understanding the complex transition from hunter-gatherers to herders, the identification of different cultural groups in the past, and identifying the presence and extent of past social networks. The final focus should be on future research directions that will benefit OES bead research, specifically more detailed approaches to understanding OES bead diversity and the expansion of experimentally derived taphonomic frameworks for identifying past human and nonhuman behaviors in OES bead assemblages. Future research should build on the growing body of detailed OES bead analyses, as they provide unique insight and a strong complement to traditional archaeological approaches to understanding past peoples, groups, and cultures during the African LSA.

This paper reports on preliminary fieldwork at the Later Stone Age site of Txina-Txina in Mozambique. Excavation yielded a long stratigraphic sequence, a large lithic assemblage, a unique decorated gastropod shell fragment and two ostrich eggshell beads—the first of their type recovered from a Stone Age context in Mozambique.

Abstract This article reports on a new project to investigate the activities of early Homo sapiens in the area of the Chotts ‘megalake’ in southern Tunisia. Excavations in 2015 and 2019 at Oued el Akarit revealed one of a number of Middle Stone Age (MSA) horizons near the top of a long sequence of Upper Pleistocene deposits. The site identified as Oued el Akarit (Sondage 8) consists of lithic artefacts, bone fragments of large ungulates and pieces of ostrich eggshell. Many of the objects are burnt. Excavation of about nine square metres revealed that these were associated with a lightly trampled and combusted occupation surface. Amongst the identified artefacts were Levallois flakes some of which could be refitted, thereby indicating the generally undisturbed nature of the occupation. The lithic finds also included side scrapers and other tools diagnostic of the MSA but significantly no bifacial or tanged tools. OSL (Optically Stimulated Luminescence) dating of the sediments and AMS (Accelerator Mass Spectrometry) radiocarbon dating of ostrich eggshell have produced uncalibrated age determinations in the range 37,000–40,000 years ago, one of the youngest ages for MSA sites in the region. This is the first example of a securely dated later MSA occupation in a riparian environment in south-eastern Tunisia.
