New ages for the post-Howiesons Poort,late and final Middle Stone Age at Sibudu,South Africa

Optically stimulated luminescence (OSL) measurements are reported for single grains of quartz from deposits within Sibudu rock shelter. Such measurements enable rejection of unrepresentative grains and application of the finite mixture and central age models to obtain the most reliable age estimates. Three types of single-grain equivalent dose (D_e) distributions were observed: one sample represented a single dose population, three samples indicated mixing between Iron Age (IA) and Middle Stone Age (MSA) deposits, and 10 samples (in addition to the three mixed samples) showed scattered distributions. The latter type resulted from differences in the beta dose received by individual grains. For these samples, the beta doses were modelled and adjusted accordingly. Ages for the 14 samples collected from MSA deposits post-dating the Howiesons Poort (HP) resulted in three age clusters, which are stratigraphically consistent with the three informally named cultural phases at Sibudu: namely, the post-HP, late MSA and final MSA. Weighted mean ages of 58.5 ± 1.4 ka, 47.7 ± 1.4 ka and 38.6 ± 1.9 ka were calculated for these phases, respectively. The three phases were separated by two occupational hiatuses with durations of 10.8 ± 1.3 ka and 9.1 ± 3.6 ka. We hypothesise that the punctuated presence of humans at Sibudu was determined by large-scale fluctuations in climate during oxygen isotope stage (OIS) 3, which resulted in alternating wet and dry periods. Phases of occupation correspond to wet periods when fresh water was available in the Tongati River, whereas intervals of site abandonment correspond to dry periods when people were forced to migrate in search of a reliable source of fresh water. Where people migrated to, remains unresolved.     

Same island, different diet: Cultural evolution of food practice on Öland, Sweden, from the Mesolithic to the Roman Period

The Mesolithic–Neolithic transition in north-west Europe has been described as rapid and uniform, entailing a swift shift from the use of marine and other wild resources to domesticated terrestrial resources. Here, we approach the when, what and how of this transition on a regional level, using empirical data from Öland, an island in the Baltic Sea off the Swedish east coast, and also monitor changes that occurred after the shift. Radiocarbon dating and stable carbon and nitrogen isotope analyses of bones and teeth from 123 human individuals, along with faunal isotope data from 27 species, applying to nine sites on Öland and covering a time span from the Mesolithic to the Roman Period, demonstrate a great diversity in food practices, mainly governed by culture and independent of climatic changes. There was a marked dietary shift during the second half of the third millennium from a mixed marine diet to the use of exclusively terrestrial resources, interpreted as marking the large-scale introduction of farming. Contrary to previous claims, this took place at the end of the Neolithic and not at the onset. Our data also show that culturally induced dietary transitions occurred continuously throughout prehistory. The availability of high-resolution data on various levels, from intra-individual to inter-population, makes stable isotope analysis a powerful tool for studying the evolution of food practices.     

Birds and burials at Ajvide (Gotland,Sweden) and Zvejnieki (Latvia) about 8000–3900 BP

Animal bones in human burials may reveal aspects of the relationship between animals and humans. This article describes the roles of birds in mortuary practices and in the ideology of Stone Age northern Europe. Bird bones from two large burial sites, Middle Neolithic Ajvide (Gotland, Sweden) and Mesolithic and Neolithic Zvejnieki (Latvia) are investigated with osteological methods. Beads and pendants were fashioned from the wing bones of waterbirds, and used in the decoration of the body or the burial dress. The jay was found in three Neolithic burials at Zvejnieki, and it may have been a totem animal for the Middle Neolithic people at Zvejnieki, and its wings or feathers were presumably attached to dresses and costumes for the dead. Bird remains in burials at Ajvide, Zvejnieki and some other Stone Age cemeteries may indicate similar features in the way of perceiving birds, especially the possible symbolic roles of waterbirds and wings. The findings are discussed from the perspective of the cosmology of historical hunter–gatherer (and herding) groups in modern Russia.     

Ancient DNA in human bones from Neolithic and Bronze Age sites in Greece and Crete

Attempts were made to detect ancient DNA (aDNA) in samples of 88 human skeletons from eight Neolithic and Bronze Age sites in Greece and Crete. Ancient DNA was absent in specimens from Nea Nikomedia, Lerna, Karaviádena (Zakro), Antron Grave Circle A and Mycenae Grave Circle A. For each of three skeletons from Antron Grave Circle B that were sampled, polymerase chain reactions (PCRs) gave products for nuclear but not mitochondrial DNA, but amplicon yield was low and inconsistent with replicate PCRs failing to give reproducible results. With specimens from Mycenae Grave Circle B, evidence for mitochondrial aDNA was obtained for four of the 22 skeletons that were studied, and at Kouphovouno evidence for mitochondrial and/or nuclear aDNA was obtained with eight of the 20 skeletons that were examined. We conclude that, although aDNA might be present in some Eastern Mediterranean skeletons from later centuries of the Bronze Age, it is not commonly found in material from this period and is likely to be absent from older material.

The Ethnoarchaeology and Field Archaeology of Grinding at Sukur, Adamawa State, Nigeria

A typology of artificial rock hollows and tentative identification of their functions is founded upon study of recent practices at Sukur. Five stages of development of equipment for grinding grain are identified and shown, using field archaeological evidence, to constitute a sequence of historical phases that extends from the Neolithic or early Iron Age to the present. The development of other types of hollows is related to this sequence. Ethnographic data are employed to estimate the use lives of grain grinding hollows, which are interpreted in terms of woman-centered familial grain-grinding units. The evidence suggests that prior to ca. AD 1600 the population density averaged two orders of magnitude less than in recent times—with important implications for regional culture history. This exploratory study demonstrates the potential of artificial hollows as evidence for the study of prehistory, culture and demographic history, and the history of landscape in Africa and beyond.     

Bedding, hearths, and site maintenance in the Middle Stone Age of Sibudu Cave, KwaZulu-Natal, South Africa

Micromorphological analysis of sediments from the Middle Stone Age site of Sibudu Cave, KwaZulu-Natal, South Africa, provides a high-resolution sequence and evidence of site formation processes of predominantly anthropogenic deposits. This methodology allows for a detailed interpretation of individual anthropogenic activities, including the construction of hearths and bedding and the maintenance of occupational surfaces through the sweep out of hearths and the repeated burning of bedding. This analysis also provides a context for evaluating other studies at the site relating to magnetic susceptibility, paleobotany, paleozoology, anthracology, and studies of ochre.     

The provenance of some glass ingots from the Uluburun shipwreck

The discovery of a Late Bronze Age trading vessel at Uluburun near Ka? off the Turkish coast offers exciting possibilities for our understanding of Bronze Age trade. On board the ship was a large consignment of glass ingots that were assumed to originate either from Mesopotamia or Egypt. This paper presents the results of major and trace elemental analyses of three deep blue and turquoise glass ingots from the Uluburun wreck, and for the first time securely demonstrates that their composition is consistent with an Egyptian origin. The compositional similarity of the glass ingots to glasses from the Mycenaean world suggests that Egypt was exporting to that region via trading ships such as that from Uluburun.
