The Middle Neolithic (4300-4000 cal. yr BC) archaeological sites in the Swifterbant area were typically regarded to represent a transitional phase between a hunter-gatherer and agricultural subsistence. The discovery of a tilled layer on one of the sites (S4) site in 2007 during a renewed excavation campaign (2004-2007) was made possible by a close cooperation between archaeologists, diatom specialists and micromorphologists. Intensive sampling and micromorphological investigation revealed that the Swifterbant cultural layers typically consists of micro-laminated deposits of phytoliths and charred plant remains with waste. This led to the reinterpretation of the sites as middens rather than settlements. At least five levels could be identified that had been tilled with some kind of hand-tool. These levels were separated by natural clay deposits and midden layers. These results, and reinterpretation of observations from two other sites in the Swifterbant area (S2 and S3) indicate that tillage and crop production formed a regular part of the subsistence of the inhabitants during the Middle Neolithic. Rather than a transitional phase, the sites investigated probably should be regarded as traces of a fully agricultural society. [ABSTRACT FROM AUTHOR]

We tested whether micro CT scanning could be used to study phytoliths and bone fragments on samples from a Middle Neolithic midden deposit from Swifterbant (The Netherlands). We scanned an untreated block sample, and an impregnated sample that was used to make a thin section of. Ample small bones or bone fragments could be discerned and identified - most of them from fish - although sieving showed that many went undetected. It was possible, however, to identify several deposition events within a few cm of stratigraphy, and distinguish deposits with cleaning refuse from bones that were discarded during or after meals. Bone fragments embedded in coprolitic material represented the ingested and excreted bone fragments. Moreover, it proved to be possible to identify articulated bones or bone fragments that would become separated and unidentifiable during sieving and to recognize specific decay patterns. Silica phytoliths could be discerned, but the resolution was not enough to use it for species identification. Overall, the greatest advantage of microCT scanning of undisturbed samples form archaeological sites seem to lie in non-destructively providing context and taphonomical information on which further sample treatment and analyses - including microsampling and micromorphology - can be based.

To investigate changes in culinary practices associated with the arrival of farming, we analysed the organic residues of over 1,000 pottery vessels from hunter-gatherer-fisher and early agricultural sites across Northern Europe from the Lower Rhine Basin to the Northeastern Baltic. Here, pottery was widely used by hunter-gatherer-fishers prior to the introduction of domesticated animals and plants. Overall, there was surprising continuity in the way that hunter-gatherer-fishers and farmers used pottery. Both aquatic products and wild plants remained prevalent, a pattern repeated consistently across the study area. We argue that the rapid adaptation of farming communities to exploit coastal and lagoonal resources facilitated their northerly expansion, and in some cases, hunting, gathering, and fishing became the most dominant subsistence strategy. Nevertheless, dairy products frequently appear in pottery associated with the earliest farming groups often mixed with wild plants and fish. Interestingly, we also find compelling evidence of dairy products in hunter-gatherer-fisher Ertebølle pottery, which predates the arrival of domesticated animals. We propose that Ertebølle hunter-gatherer-fishers frequently acquired dairy products through exchange with adjacent farming communities prior to the transition. The continuity observed in pottery use across the transition to farming contrasts with the analysis of human remains which shows substantial demographic change through ancient DNA and, in some cases, a reduction in marine consumption through stable isotope analysis. We postulate that farmers acquired the knowledge and skills they needed to succeed from local hunter-gatherer-fishers but without substantial admixture.

The archaeological sites of Hardinxveld-Giessendam de Bruin and Polderweg, situated in the Rhine-Meuse delta, are the best-preserved Mesolithic sites in the Netherlands. Due to the early appearance of domesticated animals in their faunal assemblage, they are also integral to the research of the emergence of animal husbandry in the region. This study focuses on the precise chronology of the sites, using radiocarbon dating and Bayesian modelling of both newly acquired and legacy radiocarbon dates. To mitigate the risk of erroneous dates, we dated the bone collagen of 26 herbivorous and one aquatic mammals from clear archaeological contexts and discovered that the most recent occupational phases at both sites are several centuries younger than previously thought. This is consistent with material evidence of lifestyle changes in the final phase at Hardinxveld-Giessendam de Bruin, which is now, according to our chronology, contemporaneous with the similar patterns produced in the region., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Dreshaj et al.

Suids (Sus sp.) played a crucial role in the transition to farming in northern Europe and, like in many regions, in the Netherlands pig husbandry became an important subsistence activity at Neolithic sites. Yet little is known about wild boar palaeoecology and hunting in the Late Mesolithic Netherlands with which to contextualize this transition. This paper presents the first multi-proxy analysis of archaeological suid remains in the Netherlands. It explores human-suid interactions at the Swifterbant culture sites of Hardinxveld-Giessendam Polderweg and De Bruin (5450-4250 BC) through biometric analysis, estimation of age-at-death, and stable carbon and nitrogen isotope analysis. The results reveal targeted hunting of adult wild boar in the Late Mesolithic (5450-4850 BC), with a possible shift over time towards more juveniles. The wild boar in this period are demonstrated to be of comparably large size to contemporary northern European populations and exhibiting a wide range of dietary regimes. In the final occupational period (4450-4250 BC), small suids are present, possibly domestic pigs, but there is no evidence of pig management. This study demonstrates that the nature of human-suid interactions varied over time, which may have been connected to changing environmental conditions, human mobility, and wild boar behaviour. This study also contributes the first biometric and dietary baseline for mid-Holocene wild boar in the Netherlands., Competing Interests: The authors have declared that no competing interests exist.
