  In this paper we explore temporal variation in demography and settlement intensity in southeastern Norway during the Early and mid-Holocene. In order to investigate the temporal variation in demography and settlement we have applied and compared two different proxies: Summed radiocarbon probability distributions and site count data of shoreline-dated sites. The proxies display similar patterns, and we suggest that they indicate stability in settlement in the coastal areas of southeastern Norway between 8500 cal. BCE and 2000 cal. BCE.

  In this paper, faunal remains and bone artefacts are used as a point of departure for discussing the subsistence strategies of the Early Mesolithic (9500–8300 cal BC) and Middle Mesolithic (8300–6300 cal BC) foragers in the Oslo Fjord region of Eastern Norway and the Swedish west coast. This region is a key area in discussions about the settling of present-day Norway. Due to the combination of isostatic rebound and global sea level rise, the north-eastern Skagerrak area is one of the few regions in the world where coastlines dating to the Preboreal and Boreal climatic phases are situated above present-day sea level. This unique contextual situation makes these locales the oldest sea shore sites in Europe. Throughout the period, coastal settlements are situated close to the contemporary shoreline, and the location of the sites demonstrates the fundamental importance of the maritime environment. From the coastal areas, different ecological habitats with a variety of maritime and lacustrine resources were within reach. These ancient “waterworlds” offer a possibility to explore the settlement pattern and animal utilization. Organic remains are not preserved at any coastal Early Mesolithic site; thus, the mode of subsistence must be inferred from non-anthropogenic bone collections and palaeoecological data. In the oldest phase of the coastal site Huseby Klev, dated to the beginning of the Boreal chronozone, c. 8000 cal BC, the abundance of marine mammals suggests that hunting of marine mammals was an important part of the diet. The occurrence of cod and ling as well as fishhooks confirms that fishing was also practiced. The importance of fishing seems to increase in the later Middle Mesolithic. The Middle Mesolithic faunal assemblages exhibit remarkable species diversity, with terrestrial mammals, sea mammals, birds, and fish. This is suggestive of a broad- spectrum economy. There is a wide variety of marine fish, in particular different species of the cod family (Gadidae). The most common fishing equipment from the north-eastern Skagerrak Middle Mesolithic takes the form of small fishhooks without barb. The fishhook and other bone implements were made of antler and ungulate metapodials; thus, these animals provided important raw material in addition to calories.

  The sea level low-stand period during the Early Mesolithic in the south-eastern Baltic (c. 9500–6500 BC) was followed by the transgression of vast areas. Some of the now submerged sites have yielded extensive remains of lagoonal and riverine sediments, as well as areas with trees preserved in situ. Investigations at one of the sites—Haväng in eastern Scania—have resulted in archaeological finds from the entire period. The preservation of organic materials is very good, and gives new insights into material culture and fishing technologies. Extensive surveying and hydro-acoustic mapping make it possible to draw conclusions about the timing of the introduction of stationary fishing and how this relates to cultural and natural changes. The paper proposes that riverine stationary fisheries in the southern Baltic were introduced during the Boreal period (7000 BC or earlier). These Maglemose fisheries are proposed as indirect evidence of early seascape territorialization, which must be understood in a cultural and ecological context.

  A new set of 101 radiocarbon datings on burned bone from inland sites in central Scandinavia is used here. These show a similar pattern to the previously used 261 datings on charcoal. The two dating methods thus confirm each other. They also show a great resemblance to a model proposed by Joel Boaz in 1999, based on excavation results from two inland areas. Boaz’s model has two main periods of Mesolithic inland settlement, separated by low inland use after 6000 BC, also known as the “classic hiatus.” This hiatus marks the end of what is here considered the pioneer phase. There is also an Early Mesolithic phase of inland settlement, not known in Eastern Norway, but represented in Western Norway and West Sweden. After the Early Mesolithic there was a change from the use of both inland and coast to a concentration of settlement at the coast. This period of low inland use lasted for more than 1,000 years. At 6900 BC inland settlement takes off, showing an exponential increase until 6200 BC. Here it is argued that this is not the result of an expansion from the coast, but rather a separate inland population originating from the north and east. The explanation could be the contemporary increase in woodland and in the elk population. This leads to the highest density of inland settlement during the entire Stone Age at c. 6200 BC.

  During 2010-2012 the Museum of Cultural History excavated several sites dated to the Middle Mesolithic (8300-6300 BC) in the western parts of the Oslofjord region. This has provided us with an opportunity to discuss several aspects of the period. The sites show diversity in lay out, size and organisation. This allows for well-founded interpretations of the Middle Mesolithic society, settlement systems and economy based on empirical data of high quality. Here two sites are presented as case studies: Hovland 3 with a well-dated (c. 7500 BC) dwelling structure and the contemporary site Prestemoen 1 with preserved bones. These recently excavated sites from the Oslofjord region have parallels in the Late Mesolithic period, rather than the assumed more mobile Early Mesolithic society. Already from around 7500 BC we see traces of a more stable settlement pattern and lifestyle.

  For over a decade now, the field of paleogenomics has been a key source of information for studies of prehistoric human mobility and dispersal. Although the samples of ancient DNA in these studies derive from archaeological contexts, and interpretations of the sources of detected genomic variation are made using archaeological cultures as background information, due to varietyof reasons archaeological discussion is rarely at the centre of papers that combine DNA and archaeology. With this in mind, we discuss the Early Mesolithic in Scandinavia, a case where cultural variability is great in the archaeological record but not necessarily fully grasped in studies that have attempted to combine genes and culture to create a model of early postglacial human dispersal. A common problem for all DNA studies concentrating on Mesolithic north-western Europe, is that the currently available sample material postdates the archaeologically identified timing of the pioneer colonization process and many of the subsequent cultural processes that took place alongside and after the region had been occupied. In this presentation we present an up-to-date synthesis of available archaeological data from Fennoscandia predating 7500 cal BCE and discuss it in relation to the current model of single event gene-culture co-dispersal. We specifically scrutinize the idea that the eastern component detected in Mesolithic Scandinavian hunter-gatherers in studies of ancient DNA can be directly linked to a single population event evidenced by the spread of eastern pressure blade technology along the Norwegian Atlantic coast.

  Modelling combinations of radiocarbon dates using Bayesian statistical principles is becoming an increasingly common method for research into prehistoric population dynamics. It has recently been suggested that results from such analyses should be linked with multiple proxies in order to secure a more robust validation. This paper explores population dynamics in southern Norway throughout the Neolithic period (3900-1800 BCE) by comparing two different proxies: (1) radiocarbon dates and (2) trends in material culture from occupation sites. For this study, 643 14C-dates derived from 204 Neolithic sites were analysed using SPD’s (UCL-method), while trends in material culture from 180 occupation and mortuary sites were analysed using kernel density modelling. The analysis of radiocarbon dates identified three phases of intensified relative population size in the Neolithic, which correlated well with regional changes in material culture, indicating a ‘rise and fall’ of cultural complexes. However, the three phases in the SPD’s did not follow a predictable pattern with regard to the character of the documented settlement activity, e.g. hunting, fishing and gathering compared to local food production. These findings are discussed in terms of how expected grand mediators in prehistoric societies such as migration and food production techniques are to be deciphered from results of demographic research.

  The early and mid-Holocene landscape of southeastern Norway was under a constant process of change due to shifting sea level and constant land rise. This dynamic landscape offered Stone Age hunter-gatherers concentrations of aquatic and terrestrial resources. Unlike most parts of Europe, no Holocene transgressions are documented in this region but the degree of land uplift and sea level changes has varied between the different parts of southeastern Norway. A recent study by the authors has demonstrated temporal stability in the coastal population in southeastern Norway during the early and mid-Holocene by using C14-dates as proxy. In this paper we will explore this further at a more detailed level by using the same data set to investigate the connection between settlement sites and the shifting shorelines and sea level. While earlier studies of settlement patterns have focused on limited regions we will expand on these studies and explore the coastal settlement pattern further by investigating Mesolithic sites from the entire Oslo fjord region. In order to so we will compare the temporal distribution of dates with the changing sea levels. In our approach we will adjust all C14-dated sites to the same “nill-curve” in order to directly compare different parts of the region and to investigate the connection between settlement and changing shorelines. Can we expect a clear pattern of continuity in shorebound settlement as indicated by previous studies? If and consequently when we observe variation or breaks in shorebound settlement, what are the reasons for this? Here we offer a new approach to investigate the temporal development in coastal settlement pattern in southeastern Norway. This study will also give a more detailed picture of the general temporal development in human activity in the coastal areas of southeastern Norway.

A two-way colonization pattern has been observed for most terrestrial pioneer and boreal forest species in Scandinavia after the last glacial period: one route from the south-west and another through northernmost Fennoscandia. It is generally accepted that these routes represent plant and animal populations spreading from separate glacial refuges which is manifested by genetic differences.
