Systematic consumption of non-marine gastropods at open-air Mesolithic sites in the Iberian Mediterranean region (original) (raw)

The aim of this paper is to describe the results of a study of the terrestrial gastropods recovered at the Epipalaeolithic site Balma del Gai, and comparing it with other Upper Palaeolithic and Epipalaeolithic samples from the Mediterranean region of the Iberian Peninsula. Balma del Gai is located in northeastern Spain, in the municipality of Moià, province of Barcelona. This small rock shelter lies about 50 km inland from the coast. The second layer, the middle one, (Nivell I) contains diverse Epipalaeolithic occupations dated from 12,240 110 BP to 8930 140 BP. A large amount of terrestrial gastropod shells was recovered during archaeological excavations. These shells belong to the species Cepaea nemoralis, which is very common in other contemporaneous sites from the region. The anthropic origin of the sample has been confirmed by a previous taphonomic study. New results reveal an evolution in the use of land snails as a food resource from south to north in Mediterranean Iberia: consumption of land snails began in the south with the warmer stages at the end of the Pleistocene and extended northwards during the Holocene. However, land snails were most likely only a seasonal food source, and their presence is probably correlated with the exploitation of other resources such as small mammals (rabbits) and collected plants and fruits.
Land Snails as a Diet Diversification Proxy during the Early Upper Palaeolithic in Europe
Plos One, 2014
Despite the ubiquity of terrestrial gastropods in the Late Pleistocene and Holocene archaeological record, it is still unknown when and how this type of invertebrate resource was incorporated into human diets. In this paper, we report the oldest evidence of land snail exploitation as a food resource in Europe dated to 31.3-26.9 ka yr cal BP from the recently discovered site of Cova de la Barriada (eastern Iberian Peninsula). Mono-specific accumulations of large Iberus alonensis land snails (Ferussac 1821) were found in three different archaeological levels in association with combustion structures, along with lithic and faunal assemblages. Using a new analytical protocol based on taphonomic, microX-Ray Diffractometer (DXR) and biometric analyses, we investigated the patterns of selection, consumption and accumulation of land snails at the site. The results display a strong mono-specific gathering of adult individuals, most of them older than 55 weeks, which were roasted in ambers of pine and juniper under 375°C. This case study uncovers new patterns of invertebrate exploitation during the Gravettian in southwestern Europe without known precedents in the Middle Palaeolithic nor the Aurignacian. In the Mediterranean context, such an early occurrence contrasts with the neighbouring areas of Morocco, France, Italy and the Balkans, where the systematic nutritional use of land snails appears approximately 10,000 years later during the Iberomaurisian and the Late Epigravettian. The appearance of this new subsistence activity in the eastern and southern regions of Spain was coeval to other demographically driven transformations in the archaeological record, suggesting different chronological patterns of resource intensification and diet broadening along the Upper Palaeolithic in the Mediterranean basin.

We analysed assemblages of shells of land snails and small aquatic and wetland gastropods from a late Mesolithic-early Neolithic deposit in the cave of Pico Ramos (Basque Country). Shells were recovered by hand during excavation and all excavated deposit was processed by flotation, with a 250 μm mesh to recover floating material and a 1.0 mm mesh to recover the heavy fraction. The total assemblage comprised 5780 individuals (MNI) among 33 taxa, the sieved sub-assemblage having the highest proportions of these (2841 MNI in 31 taxa) and the hand-picked sub-assemblage the lowest (698 MNI in 11 taxa). Eleven taxa were absent from the flotation sub-assemblage, although the recovered MNI (2241; 39% of the total MNI) was high. The palaeoecological implications of the results are considered. Adult and large-sized juvenile shells of the edible land snail Cepaea nemoralis are abundant in the hand-picked sub-assemblage, but it is the absence of small-sized juvenile shells in the flotation and wet-sieved sub-assemblages that permits the inference that the species was collected for consumption. Wet sieving is therefore essential, both for interpreting hand-picked samples and in particular for the recovery of representative assemblages of land molluscs.

The sedimentary record of the Vestíbulo, Mina and Torca chambers in the ancient entrance of Nerja Cave (Málaga, southern Spain) developed between around 30 and 3.6 ka cal BP. The long record of human occupation shows a dominance of terrestrial snails associated with the Gravettian, with a continuation of these types in the Solutrean when marine shells begin to be introduced. During the Magdalenian, marine bivalves are dominant. Marine molluscs reach a maximum during the Epipalaeolithic, giving rise to a shell midden formed primarily by Mytilus edulis and diverse species of Patella. The Epipalaeolithic shell midden occurs in Unit 4 and can be dated to the Pleistocene–Holocene boundary. This paper focuses on the terrestrial, marine and freshwater gastropods present in the Epipalaeolithic. Among these remains were specimens carried in by humans for both food and ornamental purposes. Others were introduced accidentally by humans, and finally, other specimens entered the cave by natural processes.
Gastropod consumption during the Late Pleistocene and Early Holocene in the Haua Fteah, Libya
2019
Land snail shell is a frequent constituent of archaeological sites, but it is rarely clear whether it represents food refuse, the remains of scavengers, or evidence for natural processes. Piercing of land snail shells enables the animal to be extracted from the shell and thus provides direct evidence for human consumption. We report pierced land snails from the Haua Fteah, Libya. The earliest pierced land snail shell in the Haua Fteah pre-dates the Last Interglacial, while the most recent is Late-Classical in age, but the largest quantities are in layers of Late-Glacial and earliest Holocene age, where they are associated with atypical microliths. Introduction Marine gastropods are major components of shell middens worldwide and are usually regarded as evidence for human consumption of the animals, except in the cases of shell middens produced during the processing of Muricids for dye production (e.g. Reese 2000, 2010) and the use of gastropods for bait (Oliver 2015).
