Early 14 C increase in high-latitude trees at 665–664 BC
The discovery of radiocarbon ( 14 C) peaks in AD 774–775 and AD 993–994 sparked the search for other anomalous events, leading to the identification of one around 660 BC. However, the ∼660 BC event appears to show a more prolonged increase, raising the question whether the event is qualitatively different. To investigate this, we measured high-latitude tree rings from Finnish Lapland, expected to be highly sensitive to energetic particle events. …
Karol – An Interdisciplinary Research Project on the Skull Collection Returned from the Karolinska Institute in Sweden to Finland
Multi-isotopic evidence reveals the emergence of a cosmopolitan community at the Luistari cemetery in Eura, Finland, during the early Medieval period (600–1130 CE)
This study examines the role of the Eura region as a nexus linking the inland with Baltic Sea trade routes. Luistari cemetery, spanning from the early Merovingian to Medieval periods, provides key insights into South-Western Finland’s socio-economic structure and communication networks. Despite its significance, this burial community’s chronological dynamics and regional role remain poorly understood. Using multi-isotopic evidence contextualised …
A Glance to the Fragmenta Membranea Manuscript Collection Through Ftir and Radiocarbon Analyses
The Fragmenta membranea manuscript fragment collection at the National Library of Finland has proved challenging to date using only traditional paleography. Therefore, radiocarbon dates can contribute to the understanding of these fragments by offering a parallel natural scientific timeline for the parchment the manuscripts are written on. In this study, we apply our previously developed method for radiocarbon dating medieval manuscripts made of …
Graves, landmarks, or sacrificial monuments? The human osteology and paleopathology of the Bronze Age burial cairns in Finland
During the Bronze Age (BA; ca. 1800–500 BC), cremation became the dominant burial practice in Finland. These BA cremations have been excavated from burial cairns in Finland for more than 150 years. This work provides new information on human osteology from this previously understudied area in northeastern Europe. The results cover the earliest period in Finnish prehistory for which large‐scale human osteological assemblages are available. In this…
Isotopic insights into the early Medieval (600–1100 CE) diet in the Luistari cemetery at Eura, Finland
In this article, we present the results of an isotopic study of diet for the early medieval (Merovingian, Viking, Early Christian) humans buried in the unique Luistari cemetery at Eura (ca. 600–1400 CE), southwestern Finland, the largest cemetery of the region. Isotope analysis was conducted on 37 humans for dentine and bone collagen (δ 13 C, δ 15 N, and δ 34 S), and five of them were also studied using compound-specific nitrogen isotope analysis…
Volumes of Worth—delimiting the Sample Size for Radiocarbon Dating of Parchment
Medieval manuscripts are invaluable archives of the written history of our past. Manuscripts can be dated and localized paleographically, but this method has its limitations. The Fragmenta membranea manuscript collection at the National Library of Finland has proved difficult to date using paleographic methods. Radiocarbon dating has been applied to manuscripts of parchment before, but a systematic protocol for radiocarbon dating of parchment has…

One of the difficult issues is the time of the ceramic technology appearance. Methods and materials. The study of the pottery technology of the Neolithic population of the Northern Caspian region is carried out in the framework of the historical and cultural approach…
Can the 14 C Production in 1055 Ce Be Affected by Sn1054
Annually resolved radiocarbon ( 14 C) measurements on tree rings led to the discovery of abrupt variations in 14 C production attributed to large solar flares. We present new results of annual and subannual 14 C fluctuations in tree rings from a middle-latitude sequoia (California) and a high-latitude pine (Finland), analyzed for the period 1030–1080 CE, to trace a possible impact of the Crab supernova explosion, occurring during the Oort minimum…
The chronology of Jäkärlä Ware – Bayesian interpretation of the old and new radiocarbon dates from Early and Middle Neolithic southwest Finland
The chronology of the eastern Fennoscandian Neolithic is organized with the help of pottery styles, one of which is southwestern Finnish Jäkärlä Ware. In this paper a number of new radiocarbon dates connected with Jäkärlä Ware and other relevant ceramic groups are presented and discussed. The radiocarbon dates of each group are modelled within a Bayesian chronological framework. Also, the potential reservoir effect in charred crust dates is estim…
The dIana database – Resource for isotopic paleodietary research in the Baltic Sea area
Paleodietary research is a complex field, which requires large sets of background information. Owing to increasing interest and activity in the field, a substantial amount of archaeological isotope baseline data exist for Northern Europe, consisting mainly of animal bone collagen δ13C, δ15N, and δ34S values. However, the data are scattered into dozens of publications written in multiple languages and less-accessible formats, making the data labor…
The advance of cultivation at its northern European limit
Dates for early cultivation in Finland obtained from pollen analysis and remains from archaeological sites are compared with the changes in population size derived from the summed calendar-year probability distributions. The results from these two independent proxies correlate strongly with one another indicating that population size and the advance of farming were closely linked to each other. Moreover, the results show that the adaptation and d…
Plant remains from the early modern garden of the manor of Kumpula, Helsinki, Finland
Event reconstruction through Bayesian chronology
Precise timing of natural and cultural events provides a foundation for understanding how past natural phenomena have driven changes in population and culture. In this study, we used high-resolution Bayesian chronology to describe an event sequence of a massive and abrupt water level decline of a large lake and the contemporaneous cultural changes that occurred in eastern Fennoscandia during the mid-Holocene. The study provides the first transdis…
An Arctic seal in temperate waters
The ringed seal ( Pusa hispida) is an early immigrant in the Baltic Basin and has since its arrival experienced substantial changes in the climate, salinity and productivity of the Basin. In this paper, we discuss the dispersal and distribution of the ringed seal during different stages of the Baltic Sea in relation to past and ongoing environmental changes. Subfossil ringed seal remains around the Baltic Sea and the Danish Straits were radiocarb…

Unexpected Problems in AMS 14 C Dating of Fen Peat
Four fen peat sequences in northern Finland were dated by the accelerator mass spectrometry (AMS) radiocarbon method in order to study past peatland dynamics and carbon accumulation patterns. Initially, plant macrofossils were used for dating. However, the dates were severely disordered, with marked inversions in all sequences. In one 140-cm peat core, for example, all ages fell within a ∼1000-yr time window. Following these unreliable results, a…
A Reevaluation of the Absolute Chronology of Cabuza and Related Ceramic Styles of the Azapa Valley, Northern Chile
The nature and extent of the political and cultural influence of the Tiwanaku state (ca. A.D. 500-1100) in the Azapa Valley of northern Chile are debated topics. The absolute chronology of these contacts also remains somewhat unclear. Much of the debate has centered on the origins and chronological position of the Tiwanaku-related black-on-red ceramic style called Cabuza. In order to reevaluate the chronological position of the Cabuza, Maytas-Chi…
On the Eve of Urbanization
The era of early urbanization in Finland coincides with large variations in the atmospheric radiocarbon concentration around the 13th–14th centuries AD. Therefore, the uncertainties of an individual 14 C date are too large to support studies of this time period effectively. In this work, we have employ tree-ring wiggle-matching methodology and used Bayesian modeling of dates to account for stratigraphical a priori information within Aboa Vetus Mu…

Stones, Bones, and Hillfort
The Bronze Age site of ķivutkalns with its massive amount of archaeological artifacts and human remains is considered the largest bronze-working center in Latvia. The site is a unique combination of cemetery and hillfort believed to be built on top of each other. This work presents new radiocarbon dates on human and animal bone collagen that somewhat challenge this interpretation. Based on analyses using a Bayesian modeling framework, the present…
Molecular Sieves in 14 CO 2 Sampling and Handling
Molecular sieves are a promising way to sample and manipulate gaseous samples for radiocarbon analyses. Molecular sieve material can adsorb CO 2 selectively, enabling sampling of CO 2 from large air volumes in a small amount of adsorbent. The sieve material can be regenerated via heating and reused without removing the sieve material from its container. This results in ease of use and reduced risks of atmospheric contamination. Because sieve cont…
Bayesian Spatiotemporal Analysis of Radiocarbon Dates from Eastern Fennoscandia
Archaeological phenomena, especially those that have been radiocarbon dated, can be utilized as indications of human activity and occupancy in space and time. 14 C dates from archaeological contexts have been used as proxies for population history events in several recent studies (e.g. Gamble et al. 2005; Shennan and Edinborough 2007; Oinonen et al. 2010; Tallavaara et al. 2010; Pesonen et al. 2011). As a step towards a larger spatiotemporal mode…
Early Subneolithic Ceramic Sequences in Eastern Fennoscandia—A Bayesian Approach
In this contribution, we establish a radiocarbon-based chronology of early ceramic sequences in eastern Fennoscandia utilizing a Bayesian approach. The data consist of 56 individual 14 C dates from charred or fermented food remains (charred crust, food residue) and birch bark tar used to seal cracks in vessels. We present the results of the models, discuss the chronological boundaries obtained, and compare the outcome with contemporary archaeolog…
C Dating of Fire-Damaged Mortars from Medieval Finland
This study focuses on radiocarbon dating of mortars that have withstood city fires and display visible fire damage effects. Some fire-damaged and undamaged original Medieval mortars from the same site have also been tested. The mortars were heated at different temperatures and then analyzed using the same preparation procedures as in 14 C dating of mortars to see what kind of changes the heating would introduce to the mineralogy, chemistry, and t…
