Which Bone to Pick: Creation,Curation, and Dissemination of Online 3D Digital Bioarchaeological Data

A fluorescence of shape-capture technologies at many different scales, including synchrotron, CT, micro/nano-CT, laser scanning, and photogrammetry, has led to a proliferation of digital data in bioarchaeology. The question remains how these new 3D datasets, alongside traditional bioarchaeological data, can be disseminated, and what ethical concerns are raised by trying to bring a sensitive topic into the ‘Open Access’ era. A survey of current resources and policies suggest the need for establishing best-practice standards. This paper outlines a sample of current resources, alongside modes of access and dissemination strategies to develop a picture of online Digital Bioarchaeological Data (DBD) use.     

Truth-Telling in the Wake of European Contact: Historical Investigation of Aboriginal Skeletal Remains from Normanton

This study heeds the call for a ‘truth-telling’ of injustices carried out on Aboriginal communities during the colonial acquisition of Australia as stated in the Uluru Statement from the Heart 2017. Here, we discuss the lives of eight Indigenous people buried in Normanton in north-west Queensland (QLD) who died and had their remains collected in the late 1890s as scientific specimens. The remains were later repatriated to the community before being further exposed by erosion in 2015. With the consent and participation of local traditional owners—the Gkuthaarn and Kukatj people—this assessment utilised bioarchaeological, historical and anthropological methodologies to gain a better understanding of Indigenous life and health on the Australian colonial frontier. Gkuthaarn and Kukatj people were engaged throughout the investigation, and statements throughout this piece made by them illustrate how bioarchaeology can inform on past injustices in Australia’s history, bringing them into the public consciousness and aiding the transition to reconciliation through ‘truth-telling’.     

Opportunities and constraints for intensive agriculture in the Hawaiian archipelago prior to European contact

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km² of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km², all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial.     

Variation in Venues of Slavery and Freedom: Interpreting the Late Eighteenth-Century Cultural Landscape of St. John, Danish West Indies Using an Archaeological GIS

An archaeological GIS is used to examine the late eighteenth-century cultural landscape of St. John, US Virgin Islands. Land use patterns are reconstructed using a combination of historic maps, tax records, and survey reconnaissance. The study demonstrates significant, heretofore undocumented, transitions taking place that reflect dynamic cultural and economic change within Danish West Indian plantation society that includes a significant trend towards land ownership by free-colored St. Johnians more than a half a century before emancipation. These venues of freedom are discussed in relation to broader patterns of estate consolidation and economic shifts.     

Sources and composition of fluids associated with fluorite deposits of Asturias (N Spain)

The fluorite deposits of Asturias (northern Iberian Peninsula) are hosted by rocks of Permo‐Triassic and Palaeozoic age. Fluid inclusions in ore and gangue minerals show homogenization temperatures from 80 to 170°C and the presence of two types of fluids: an H₂O–NaCl low‐salinity fluid (<8 eq. wt% NaCl) and an H₂O–NaCl–CaCl₂ fluid (7–13 wt% NaCl and 11–14 wt% CaCl₂). The low salinity and the Cl/Br and Na/Br ratios (Cl/Br_molar 100–700 and Na/Br_molar 20–700) are consistent with an evaporated sea water origin of this fluid. The other end‐member of the mixture was highly saline brine with high Cl/Br and Na/Br ratios (Cl/Br_molar 700–13 000 and Na/Br_molar 700–11 000) generated after dissolution of Triassic age evaporites. LA‐ICP‐MS analyses of fluid inclusions in fluorite reveal higher Zn, Pb and Ba contents in the high‐salinity fluids (160–500, 90–170, 320–480 p.p.m. respectively) than in the low‐salinity fluid (75–230, 25–150 and 100–300 p.p.m. respectively). The metal content of the fluids appears to decrease from E to W, from Berbes to La Collada and to Villabona. The source of F is probably related to leaching of volcanic rocks of Permian age. Brines circulated along faults into the Palaeozoic basement. Evaporated sea water was present in permeable rocks and faults along or above the unconformity between the Permo‐Triassic sediments and the Palaeozoic basement. Mineralization formed when the deep brines mixed with the surficial fluids in carbonates, breccias and fractures resulting in the formation of veins and stratabound bodies of fluorite, barite, calcite, dolomite and quartz and minor amounts of sulphides. Fluid movement and mineralization occurred between Late Triassic and Late Jurassic times, probably associated with rifting events related to the opening of the Atlantic Ocean. This model is also consistent with the geodynamic setting of other fluorite‐rich districts in Europe.     

A CHARACTERIZATION OF THE COMPOSITIONAL VARIATIONS OF ROMAN SAMIAN POTTERY MANUFACTURED AT THE LEZOUX PRODUCTION CENTRE

The study addresses the chemical variations for Roman Samian wares manufactured during various periods at different workshops within the Lezoux production centre. Instrumental neutron activation analysis and inductively coupled plasma spectrometry were used to determine the chemical constituents of the pottery. The two techniques were evaluated based on the capacity of each to identify the same compositional groups for Lezoux Samian with the use of multivariate statistics. The compositional analysis redefines and clarifies how potters used the clay sources at the site to produce fine wares. The results indicate that the majority of potters from different workshops at Lezoux shared the same clay source during the second century AD.     

NEUTRON ACTIVATION ANALYSIS OF AD 1660–1930 EUROPEAN COPPER-COLOURED BLUE GLASS TRADE BEADS FROM ONTARIO,CANADA

Blue glass trade beads from well-dated late seventeenth- to early twentieth-century sites and collections have been analysed non-destructively by instrumental neutron activation analysis. The beads display enough variations in their elemental contents to allow us to characterize the different chemistries. The implication of these results is that similar chemical analyses of blue beads from undated archaeological sites may be used to help date the sites, since each bead chemistry has a specific earliest period.     

CHEMICAL ANALYSIS OF COPPER ALLOY TRADE METAL FROM A POST-CONTACT HURON SITE IN ONTARIO,CANADA

Fifty-three copper-based metal fragments, recovered from the Robitaille site in southcentral Ontario, were analysed by neutron activation to establish their chemical make-up and to sort them by their trace elemental chemistries. Three different European copper samples, one brassy copper and 48 brass samples with five different chemistries were found. As few as eight trading actions may account for all of the recovered European metal fragments.
