In this study, we aim to extend the chronological, geographical, and societal scope of previous bioarchaeological research on infant diet and age at weaning in Britain in the past through the analysis of the large medieval and post‐medieval skeletal assemblage from St. Nicholas Kirk, Aberdeen, Scotland. Stable carbon and nitrogen isotope data were obtained from rib collagen from 67 sub‐adults across the two phases and were compared with mean adult female dietary isotope values. Nitrogen isotope data were modelled using the R Package WARN, along with previously published data sets, to provide quantitative age estimates for the commencement and completion of weaning at St. Nicholas Kirk and other medieval and post‐medieval sites. Data from Phase A (12th–15th century AD) suggest that breastfeeding may have continued up to and beyond the age of 2 years, likely in combination with other foods. This complements previously published data from urban and rural medieval contexts in England, highlighting similarities in infant feeding practices across very different contemporary populations. Data from post‐medieval Phase B at St. Nicholas Kirk (15th–18th century AD) give new insights into early modern period breastfeeding and weaning practices, indicating that weaning commenced soon after birth and was completed relatively early (within a year). These data bridge the gap between previously published studies on medieval and late 18th‐ to 19th‐century populations from the British Isles and suggest that trends observed at later urban sites may be rooted in preceding centuries, although the underlying reasons for this change are difficult to elucidate. Contributing factors may include the social and religious changes that occurred in the post‐reformation period, such as the decrease in the use of wet nurses, changes in the availability and acceptability of artificial feeding, increased urbanism, and even changes in the socio‐economic status of those interred in the Kirk.

This volume presents the results of archaeological fieldwork undertaken along the River Dee, Aberdeenshire, north-east Scotland, by the Mesolithic Deeside voluntary community archaeology group between 2017 and 2019. A total of 42 fields were investigated, from which over 11,000 lithics were recovered, representing at least 15 archaeological sites and a span of human activity covering some 10,000 years from around 12,000 BC to c 2000 BC. Finds from the Late Upper Palaeolithic, Mesolithic, Neolithic and Bronze Age were present. Work comprised fieldwalking, test pitting, specialist analysis, and small-scale excavation. The investigation described here is significant not just for the light it throws on the early prehistoric populations along the River Dee but also for the methodology by which investigation was undertaken, as this provides a potential model for work in other areas. Both aspects are covered in the report. The River Dee flows between postglacial gravel and sand terraces, the structure of which has played an important role for the early settlers of the area, and this is covered in some detail in order to provide the physical background framework for the sites. There are also sections on more specialised geophysical and geoscience techniques where these were undertaken, together with a summary of research on the palaeoenvironmental conditions throughout the millennia of prehistory. The artefactual evidence comprises lithic assemblages which were all catalogued as fieldwork progressed; the contents of each site are presented, together with more detailed analysis of the finds from test pitted sites. Finally, given the rich archaeological record from the area, the results of the present project are set into the wider context of the evidence for prehistoric settlement along the river, and there is consideration of future directions for further fieldwork. While all authors have contributed to the whole volume, individual sections that present specialist work by specific teams have been attributed. The distribution maps and GIS are the work of Irvine Ross. Dates given are calibrated BC dates. The Nethermills Farm NM4 dates are calibrated using the Oxford Radiocarbon Accelerator Unit calibration program OxCal 4 (Bronk Ramsey 2009) and their date ranges are calibrated using the IntCal13 atmospheric calibration curve (Reimer et al 2013). Optically stimulated luminescence (OSL) was used to profile sediment accumulations on some of the sites and obtain information relating to site formation, but it was not used for dating in any of the projects.

Hudson Platform underlies an area of 971 250 km2, more than half of which is covered by the waters of Hudson Bay, James Bay, Hudson Strait, and Foxe Basin. the region has potential for a variety of economic commodities, including petroleum and natural gas, oil shale, lignite, lead and zinc, and industrial minerals such as salt, gypsum, and limestone. The principal emphasis over the years has been placed on exploration for oil and gas, first in the onshore areas of Moose River Basin, and in more recent years in the onshore and offshore regions of Hudson Bay Basin. Lignite deposits that have long been known to occur along the extreme southern margins of Moose River Basin have also been investigated from time to time for about a century, but have not been exploited commercially. Promising industrial mineral deposits including salt, gypsum, clay, sand, and limestone are known in widely separated parts of the platform, but have remained undeveloped owing to their great distance from densely populated regions of the country.
