Site Identification and Correlation Using Geoarchaeological Methods at the Cabeço do Porto Marinho (CPM) Locality, Rio Maior, Portugal

Several geoarchaeological techniques have been employed in evaluating an open-air site within a uniform sand matrix, near Rio Maior, Portugal. Electrical resistivity data, acquired at the Upper Palaeolithic site complex of Cabeço do Porto Marinho (CPM), delineated an important new occupational locus. This result was confirmed, first by auger testing which recovered subsurface artefacts, and then by direct excavation. In addition, 107 samples were recovered at the site for magnetic susceptibility measurements. Comparisons between magnetic susceptibility profiles from two loci, including the new area at CPM, show distinctive patterns which allow direct correlation between the occupation areas. These methods provide quick and inexpensive means for investigators to evaluate new sites or to correlate between and within sites, without resorting to other more time-consuming and expensive techniques.

The evolution of strength,elasticity and rupture behaviour of birch tar made with ‘double-pot’ techniques during tar cooking

Birch tar was the first adhesive produced by humans. Its study has consequences for our understanding of human evolution and the development of specialised craftsmanship. One of the better-documented birch tar making methods is the ‘double-pot’ technique, where two containers are used, one containing bark, the other collecting the tar. Birch tar made with double-pots has low viscosity and bad adhesive properties. To obtain a usable adhesive, it must be reduced in volume by cooking. We investigate the evolution of tar’s mechanical properties during cooking. We use lap-shear tests to investigate strength, stiffness and failure behaviour. We found that tar must be cooked for 90 min to acquire adhesive properties. When cooked for longer, strength and stiffness increase over a 30 min lasting time span. Cooking for even longer, beyond this 30 min window, produced a substance that could no longer be used as an adhesive. The implications are that tar cooking requires a high level of skill because specific signs indicating the desired properties must be recognised during the process. Tar cooking constitutes a supplementary investment in time and resources and appears to be associated with a certain degree of risk.     

Luminescence dating of anthropogenic deposits from Tall Zarʿa in the Jordan Valley

This study uses quartz-based optically stimulated luminescence dating to determine when a massive fortification wall (W11186) was constructed in the archaeological site of Tall Zarʿa in the Jordan Valley. A total of 11 samples of sediments were taken from a trench on the north side of the wall (extramuros). The extracted quartz grains had good luminescence characteristics and were identified as well bleached by comparison with feldspar infrared-stimulated luminescence (IRSL) ages. The optical ages showed that the deposition against the wall occurred in two different periods. The first was around 3.20 ± 0.07 ka ago (Iron Age), and the second was around 2.28 ± 0.08 ka (Hellenistic period). Human activity was evident because of the intermixing of cultural material with the presumed naturally deposited units.     

Early fetal maturity assessed from patterns of ossification in the hand and foot

The assessment of fetal age at death is fraught with many complications and often the determination of the maturity of the fetus is a more realistic solution to the question of fetal viability. This study examines the pattern of appearance of primary centres of ossification in the fetal hand and foot, in an attempt to construct a maturity continuum. The results show that completion of ossification in the hand precedes that in the foot and generally occurs in a more regular pattern. The method proves useful at assessing fetal maturity between the third and tenth months of intra-uterine life. In addition, the relationship to other major centres of ossification is considered.
