During the northern European Mesolithic, new types of objects were ornamented with different geometric motifs. Many examples, however, are stray finds and their dating is poorly understood. The authors present new AMS radiocarbon dates for ornamented artefacts from Pomerania that contribute to an absolute chronology of Mesolithic art and allow for new consideration of connections between cultural groups in the western Baltic region. A baton, featuring an anthropomorphic figure, dates to the end of the Boreal period; three other objects date to the early Atlantic period, revealing a combination of regional and local innovations. The results demonstrate the value of absolute dating of stray finds for refining knowledge of wider cultural trends.

Archaeological fieldwork at Hjarnø Sund in Horsens Fjord (eastern Jutland, Denmark) has explored an eroding Mesolithic shell midden. Its stratigraphy is characterized by two layers, containing marine mollusk taxa typically collected by Mesolithic hunter-gatherers for food. In the field, the lower layer appeared to be dominated by oysters (Ostrea edulis), while the upper one by cockles (Cerastoderma edule), which was confirmed by our zooarchaeological study. Accelerator mass spectrometry radiocarbon (AMS 14C) dating on shells and paired charcoal samples from the two layers indicate that these are chronologically consecutive (separated by as little as 0–163 yr [95.4%]) and that the oyster-to-cockle shift dated between ~5500–5300 and ~5300–5200 cal BC (around or just after the Kongemose/Ertebølle transition). The shell midden at Hjarnø Sund is, thus, one of the oldest-known in Denmark, demonstrating that intensive shellfish exploitation was a hallmark of the Ertebølle culture from its inception. Oyster-to-cockle shifts, thus, also occurred at times other than the Mesolithic–Neolithic Transition and may have been ultimately caused by local shoreline displacements, resulting from changes in sedimentation, possibly induced by drops in relative sea level.

Shallow oval bowls used on the Baltic coast in the Mesolithic have been suggested as oil lamps, burning animal fat. Here researchers confirm the use of four coastal examples as lamps burning blubber—the fat of marine animals, while an inland example burned fat from terrestrial mammals or freshwater aquatics—perhaps eels. The authors use a combination of lipid biomarker and bulk and single-compound carbon isotope analysis to indicate the origin of the residues in these vessels.

In an earlier contribution to Archaeological Dialogues (4.2), Raemaekers discussed the relationships between the Swifterbant and Ertebølle cultures of respectively the mesolithic Low Countries and southern Scandinavia, calling for a more regional approach to the study of mesolithic western Europe. In this comment, recent ceramic studies from southern Sweden are used to draw attention to regional variability in the Scandinavian Mesolithic.

The slopes of the Tågerup promontory in western Scania contain one of the largest known Mesolithic settlements that has ever been excavated in Scandinavia. The Tågerup site displays a unique combination of huts and houses, graves and wooden implements, flints and bones which constitute a 1500-year-long Mesolithic occupation sequence, dated 6500–5000 cal BC. During that time, there were gradual but far-reaching changes in settlement structure and organization, the use of the landscape, flint technology and food procurement strategies.
