<p>In 2015-2017, East Jutland Museum excavated a series of well-preserved prehistoric and early historic trackways at Kastbjerg Å in the Kastbjerg Å river valley (eastern Jutland, Denmark). In this article, we will present the earliest of the in situ preserved structures, the Middle Neolithic trackway A20, and the high-precision dating of this structure. Dendrochronological dating of wood sequences provides very precise ages for archaeological timbers from buildings or structures, such as bridges or ships. This is not possible, however, when the dendrochronological samples lack sapwood, if the wood sequence has too few rings to provide definite placement on the dendrochronological master curve, if the wood sequence falls outside the range of the master curves or if the species of wood is not suitable for dendrochronological analysis. Here, we date a wood sequence of an alder tree from trackway A20 using the radiocarbon wiggle-match method to 2911 ±5 BC. The function of the trackway and the significance of the Neolithic river crossing at the Kastbjerg Å site are discussed in the light of European parallels and the regional cultural context.</p>

<p>Tanning is among the most polluting industries in the world. Industrial-produced hides and skins are fully or pre-tanned with highly polluting chromium salts. The purpose of the study was to gain new knowledge about Iron Age tanning methods to clarify whether sustainable tanning methods can be developed based on this. Fur skin capes, uncovered in Jutland bogs, from Baunsø Mose (20-220 AD), Borremose I (365-116 BC), Huldremose I (1-174 AD) and Vindum Mose (386-203 BC) were analysed by Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-FTIR), Gas Chromatography-Mass Spectrometry (GC-MS) and morphological assessment of the skin fibres to identify tanning substances and material condition. Analyses were supplemented with source studies of previous visual assessment of the capes and measured shrinkage temperature of leather and skins excavated from bogs. Our results show that only the samples from Baunsø Mose, Borremose I and Huldremose I contain vegetable tannins. Furthermore, Baunsø Mose contains cow fat and Borremose I, Huldremose I and Vindum sheep fat. All contain indications of the presence of aluminum and iron compounds. The samples are decomposed to varying extents. Remnants from conservation were detected on Huldremose I, Baunsø Mose and Vindum Mose.</p>

<p>Birch tar has been identified as the predominant adhesive used for hafting purposes in the European Mesolithic and Neolithic. Its role in the manufacture of composite tools and weapons comprising wooden, bone and flint components attests its importance during these periods. The discovery of birch tar lumps, some bearing tooth imprints, suggests a broader range of functions beyond its adhesive properties. In this study, we present an analysis of five residues from two sites (Syltholm II and Strandholm I) that have been excavated through the Femern project, with the aim to shed light on the adhesives used in relation to their functions. Through chemical analyses, we show that birch tar constitutes the main component of two lumps and one chewed piece. We also found that birch tar served to haft a bone point within leister prongs, providing new information on its previously unknown role in composite fishing tool technology. These findings have significant implications for our understanding of the functional role and performance of birch tar in aquatic environments.</p>

<p><strong>Abstract</strong></p> <p>This article summarizes an attempt at reconstructing and using T-shaped wooden spades as well as reflecting on the connection between structures and resource use around Knudmosen near Herning. However, an important limitation on this process is that very few spades are dated. The conclusion is that the spades are relatively easy to produce and well suited to digging peat.</p>

<p>Sheep and goats are often considered to be the oldest livestock animals in Denmark. In this contribution, we present the results of ZooMS measurements from seven ovicaprid bones from the Femern project, an excavation in the area of the former Syltholm Fjord (Lolland, Denmark). The bones were morphologically identified as sheep or goats and represented the oldest dated remains of both species in Denmark. However, the ZooMS analysis showed that more than half of the morphological identifications were incorrect. For the other samples, we refined the identifications. Hence, our study confirms that indications of sheep and goat husbandry based on bone morphology alone should be treated with caution. The probability of misidentification in our case was high, even in the case of well-preserved bones.</p>

<p>This article advocates for the formal adoption of a responsive approach in Danish field archae-<br />ology, utilising a recent case study to exemplify its practical application. In contrast to adhering strictly to predetermined strategies, responsive archaeology underscores the importance of ongoing evaluation and prioritisation during fieldwork to optimise knowledge acquisition and research potential. Despite the informal practice of a responsive approach in many museums within Danish field archaeology, it lacks formal recognition as a legitimate working approach. To accommodate the continual assessment of features, structures, and contexts throughout excavation, guiding methodological choices and preferences, the proposed solution recommends incorporating a prioritisation field into our on-site recordings and then transferring these entries into our archaeological databases and GIS repositories. This would allow archaeologists to self-assess and document the priority assigned to each target during fieldwork, for better post-excavation analysis. This adaptive approach aims to empower excavation teams, enhance transparency, and unlock new potential for future research and excavation strategies.</p>
