At Tell Aswad, a Pre-Pottery Neolithic B site in Central Levant, a number of marine shell beads were found. Within this assemblage, the Cypraeidae specimens are the most numerous (14 objects). The present study reveals that several techniques were used for manipulating cowrie beads: grinding or hammering, engraving, drilling, etc. Local use wear observed on some areas as well as the location of the perforations are related to various attachment systems. Finally, the decorated incisions made on the ventral and lateral faces of some shell cowries, are one of the most original aspects for shell bead-making in the PPNB period in the Levant.

The production and use of shell tools has been reported from the Neolithic (c. 6500-3300 BCE) to the Late Bronze Age (c. 1600-1300 BCE)-or the Early Iron Age c. 1300-1000 BCE)-along the eastern shores of the Arabian Peninsula. The latter are described as large bivalve shells whose ventral margin has been retouched. However, to date, no functional analysis has been performed to understand the use of these unusual tools, despite the recognised importance of marine resources in the cultural development of Protohistoric societies in this region. This paper, therefore, aims to present the findings of a large number of worked shell valves collected from excavations at Neolithic sites in the Umm al-Quwain area in the Northern United Arab Emirates, over the past 20 years. It introduces the first functional study of shell tools in the Arabian Peninsula and contributes to the knowledge of techno-cultural processes among the Neolithic coastal communities of this area. Comparisons with experimental specimens have allowed us to highlight the use of shell tools for various activities, including butchering and woodworking tasks, and the processing of animal skins in-line with the production and use of ochre. Most of the specimens studied evidenced use-wear resulting from the processing of vegetal fibres, suggesting basketry or rope production. Although further work is required on material retrieved from other sites in the region, the results from the Umm al-Quwain area already constitute a huge step forward in reconstructing past productive activities during the Neolithic, opening a new area of research for the Archaeology of Eastern Arabia.
Shell Tools and Use-Wear Analysis: a Reference Collection for Prehistoric Arabia
Journal of Archaeological Method and Theory, 2023
Prehistoric and Archaeological research has pointed out the role of marine resources in modern humans' cognitive and cultural developments. Maritime adaptations constitute a key component of the sociocultural evolution in Eastern Arabia. During the Neolithic (c. 6500-3300 BCE), it is expressed by the colonisation of offshore islands supported by advanced seafaring and the exploitation of marine resources not only for staple food but also for obtaining hard animal materials used for both symbolic and technological productions, respectively in the form of personal adornments and tooling. Although tools made of retouched large marine mollusc shells are reported on several sites, no detailed study has been conducted on their function and role within the socio-technological processes. The present study introduces a prospective approach for the functional analysis of archaeological shell tools from Eastern Arabia. A reference collection of use-wear traces made experimentally has been built: it compiles the results of 65 experiments (23 are documented and illustrated in the present study), including the processing of various animal, vegetal, and mineral materials. Use-wear traces have been observed and described using both low and high-power magnifications (conducted mainly at 100 ×). It provides helpful methodological support for future comparisons with archaeological specimens. The procurement conditions of the shell valves and the techniques of retouch have been discussed in detail, allowing further considerations on the degree of the socio-technological investment devoted to these peculiar artefacts.
Recent studies have shown that the use of aquatic resources has greater antiquity in hominin diets than previously thought. At present, it is unclear when hominins started to habitually consume marine resources. This study examines shellfish exploitation from a behavioural ecology perspective, addressing how and when past hunter-gatherers from the Levant used coastal resources for subsistence purposes. We investigate the seasonality of shellfish exploitation in the Levantine Upper Palaeolithic through oxygen isotope analysis on shells of the intertidal rocky shore mollusc Phorcus (Osilinus) turbinatus from the key site Ksâr 'Akil (Lebanon). At this rockshelter, multi-layered archaeological deposits contained remains of both marine and terrestrial molluscs in relatively large quantities, which were consumed and used as tools and ornaments by the occupants of the site. Our results indicate that at the start of the Initial Upper Palaeolithic (IUP), there is no evidence for shellfish consumption. Humans started to take fresh shellfish to the rockshelter from the second half of the IUP onward, albeit in low quantities. During the Early Upper Palaeolithic (EUP) shellfish exploitation became increasingly frequent. Oxygen isotope data show that shellfish exploitation was practised in every season throughout most of the Upper Palaeolithic (UP), with an emphasis on the colder months. This suggests that coastal resources had a central role in early UP foraging strategies, rather than a seasonally restricted supplementary one. Year-round shellfish gathering, in turn, suggests that humans occupied the rockshelter at different times of the year, although not necessarily continuously. Our oxygen isotope data is complemented with broader-scale exploitation patterns of faunal resources, both vertebrate and invertebrate, at the site. The inclusion of coastal marine resources signifies a diversification of the human diet from the EUP onward, which is also observed in foraging practices linked to the exploitation of terrestrial fauna.
