A survey at Dahshur, Egypt, employed 3-D ground-penetrating radar (GPR) in an attempt to locate pharaonic boat burials at the pyramid complex of King Senwosret III. In AD 1894, the original excavator reported finding five or six boats; however, only four “Dahshur boats” are known in museum collections today. The suspected site of the lost boat burial(s) lay beneath the large 1894 excavation backfill pile. The steep topography of the backfill required nonstandard GPR processing methods to accurately image the subsurface of the site. Although revealing no definitive traces of any remaining boats, imaging results did indicate discernible strata associated with the original naturally deposited surface, an excavated boat pit, debris and fill associated with either its original creation or its excavation, and deeper, presently unidentified archaeological remains.  相似文献

The recognition that bone strontium/calcium ratios reflect dietary levels of strontium and that seawater has a high strontium content led some archaeologists to infer that seafood consumption produces high Sr/Ca ratios in bone. Analyses of seawater and of marine organisms reveal, however, a marine trophic effect comparable to the trophic effect seen in terrestrial food chains. This marine trophic effect reduces the Sr/Ca levels in seafood such that marine dietary resources have Sr/Ca levels comparable to those of terrestrial resources. Thus, bone Sr/Ca ratios can not differentiate consumption of marine and terrestrial resources. Also, Sr/Ca of bones from archaeological sites where seafood was an important component of diet were found to be within the range of entirely terrestrial diets.

We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800–3000 cal BC), Chalcolithic (ca. 3000–2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500–2200 cal BC) and the Bronze Age (ca. 2200–1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by evidence of trauma and disease found on numerous skulls in the collection. Since no clear associations of specific grave goods with certain individuals based on sex or age could be determined, the only suggestion of social inequality lies in the burial practice itself, where certain individuals were interred in caves while others were not.  相似文献
