Inside the "African Cattle Complex": Animal Burials in the Holocene Central Sahara
Cattle pastoralism is an important trait of African cultures. Ethnographic studies describe the central role played by domestic cattle within many societies, highlighting its social and ideological values well beyond its mere function as 'walking larder'. Historical depth of this African legacy has been repeatedly assessed in an archaeological perspective, mostly emphasizing a continental vision. Nevertheless, in- depth site-specific studies, with a few exceptions, are lacking. Despite the long tradition of a multi-disciplinary approach to the analysis of pastoral systems in Africa, rarely do early and middle Holocene archaeological contexts feature in the same area the combination of settlement, ceremonial and rock art features so as to be multi- dimensionally explored: the Messak plateau in the Libyan central Sahara represents an outstanding exception. Known for its rich Pleistocene occupation and abundant Holocene rock art, the region, through our research, has also shown to preserve the material evidence of a complex ritual dated to the Middle Pastoral (6080-5120 BP or 5200-3800 BC). This was centred on the frequent deposition in stone monuments of disarticulated animal remains, mostly cattle. Animal burials are known also from other African contexts, but regional extent of the phenomenon, state of preservation of monuments, and associated rock art makes the Messak case unique. GIS analysis, excavation data, radiocarbon dating, zooarchaeological and isotopic (Sr, C, O) analyses of animal remains and botanical data are used to explore this highly formalized ritual and lifestyles of a pastoral community in the Holocene Sahara

Examples of excavated archaeological features.
<p>View of the excavations at 07/39 C2 and C3 (A), with detail of the skull from C3 (B). From monument 07/39 C1, the engraved boulder reused as trapping stone and then as building material (C).</p
Botanical remains.
<p>Fruits of <i>Rumex cyprius/vesicarius</i> from structures 07/79 C1 (a, c = sample mc1; b, e = sample mc3) and 07/110 C1 (d = sample mc4). Record a still preserves the membranaceous parts of one wing; b has the remains of the wings, while records c and d lost their wings; d has still some purple colours in the remains of the veins (see detail).</p
