The fourth season of the Burials and Identity component of the Desert Migrations Project in 2010 focused on completion of excavation work at two main cemeteries (TAG001 and TAG012) and smaller-scale sampling work at a number of nearby cemeteries. The investigation of a number of burials in a semi-nucleated escarpment cemetery TAG063 produced interesting new information on Proto-Urban Garamantian funerary rites, dating to the latter centuries BC. The excavations at TAG001 were extended to two areas of the cemetery characterised by different burial types to the stepped tombs that were excavated in 2009. A second type of fairly monumental burial was identified, but these had been heavily robbed and it was not possible to demonstrate conclusively that these pre-dated the stepped tombs. Most of the other burials excavated were simple shaft burials and were relatively sparsely furnished with imported goods, in comparison with the larger tombs, though quite a lot of organic material was identified (matting, wood, gourds, textiles and leather). At TAG012, a series of additional mudbrick tombs was emptied. All had been robbed, but pockets of the original fill and associated finds survived intact, yielding some interesting assemblages. The majority of these tombs appear to be Late Garamantian, though some contained artefacts from much earlier times.
