The Northern European Mesolithic is well known for the manufacture of composite tools and weapons for specialised purposes. A composite implement recovered from the Early Holocene site of Krzyż Wielkopolski 7 in Poland, dated to the Preboreal/Boreal transition, raises questions about expediency versus efficiency in the fabrication of these artefacts. Here, the authors characterise its materials and production: a bone splinter mounted on a shaft of pine wood, secured with bast ligatures coated in birch bark tar. While the manufacture of the implement's individual components can be characterised as ‘expedient’, the finished implement is, however, complex, efficient and durable.

It is often claimed that changes in material culture signify adaptations to changing environments. Deploying novel conceptual models and computational techniques, research funded by the European Research Council seeks to reconstruct the patterns and processes of cultural transmission and adaptation at the turbulent transition from the Pleistocene to the Holocene.

Only a limited number of radiometric dates for the Final Palaeolithic and the first half of the Mesolithic are available from the southeastern Baltic. This paper presents eight new Late Pleistocene/Early Holocene radiocarbon accelerator mass spectrometry (14C AMS) ages of osseous artifacts housed at the Kaliningrad Regional Museum of History and Art. These artifacts include one piece of worked reindeer (Rangifer tarandus) antler, three axes of the so-called Lyngby type, one bone point, one uniserial harpoon, one so-called bâton percé antler shaft, and one slotted bone. All the samples were successfully dated and yielded five Late Pleistocene and three Early Holocene ages, including the hitherto earliest age for human occupation in the Eastern Baltic. The dates include not only a surprisingly early date for a bone point (for this region), but also some dates that contradict expected ages based on traditional typological assessment. Our study significantly adds to the still small number of existing absolutely dated artifacts from the region and proposes new ways of viewing the Final Palaeolithic and Early Mesolithic chronology in the southeastern Baltic.

The carved wooden object uncovered from the Shigir peat bog in the Sverdlovsk region towards the end of the nineteenth century remains one of the oldest, known examples of monumental anthropomorphic sculpture from anywhere in the world. Recent application of new analytical techniques has led to the discovery of new imagery on its surface, and has pushed the date of the piece back to the earliest Holocene. The results of these recent analyses are placed here in the context of local and extra-local traditions of comparable prehistoric art. This discussion highlights the unique nature of the find and its significance for appreciating the complex symbolic world of Early Holocene hunter-gatherers.

In this article, we examine aspects of the Postglacial colonization processes that took place in central Norway during the Early Mesolithic (c. 9500–8000 cal bc). The distribution of sites from this period shows that the colonizers approached and exploited two very different landscapes and resource situations—from archipelagic to alpine. Based on twelve artefact assemblages from central Norway we investigate how colonizing populations met the challenge posed by varying ecozones. Did they organize their settlements and technologies in similar ways or did they modify sites and activities in relation to the different locations? The aspects studied are site organization, artefact composition, projectiles, and lithic raw material use. It appears that the sites are of a similar size and structure across ecozones. Apart from some variations in tool composition, there is no evidence in the lithic material for any technical adaptation towards specific ecozones. We conclude that using a standard, generalized lithic technology, combined with high mobility and small group size, enabled the colonizing groups to overcome the risks and difficulties associated with settling and seeking out resources in new and unknown landscapes.

The authors rewrite the character of Early Mesolithic settlement in Europe with their new research at one of its most famous sites. The picture of small mobile pioneering groups colonising new land is thrown into contention: far from being a small hunter-gatherer camp, Star Carr in 9000 cal BC extended for nearly 2ha and involved the construction of an estimated 30m of lakeside waterfront and at least one post-built house. With some justice, they suspect that the ‘small groups’ of Early Mesolithic Europe may have their rationale in the small excavations of archaeologists.

The Sujala site in northern Finnish Lapland is a reindeer hunters' camp from the early post-glacial period, discovered by the authors in 2002. The site was originally linked with the Preboreal occupation of the north Norwegian coast, but further excavations and analyses indicate that it actually represents a totally new phenomenon: evidence for an eastern influx into Lapland around the Preboreal–Boreal transition. This discovery has far-reaching implications for the colonisation of north Scandinavia, but also for the subsequent development of Early Mesolithic settlement in northern Finland and Norway.

Recent revision of the radiocarbon calibration curve for the early Holocene has implications for the ‘absolute’ date of Mesolithic sites such as Star Carr, and for their relationship to the timescale of early Holocene environmental change.
