    Dental health of Vikings from Kopparsvik on Gotland2020Ingår i: International journal of osteoarchaeology, ISSN 1047-482X, E-ISSN 1099-1212, Vol. 30, nr 4, s. 551-556Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The prevalence, distribution, and location of dental caries were studied in complete and partial human dentitions dating from the Viking Age dating (900-1050 AD) excavated in Kopparsvik on island of Gotland, Sweden. 18 individuals and a total of 370 teeth were examined, using a strong light source and dental probe. Carious lesions were found in a large number of the individuals, 14 out of 18. The percentage of teeth affected by caries (11,9%) corresponds well with studied skull materials from the same period. The surface most susceptible to caries was the occlusal surface, whereas only a few proximal lesions and one single carious root surface was found. The tooth most commonly affected by caries was the mandibular first molar. The tooth most commonly missing ante-mortem was also the mandibular molar, and the tooth most commonly missing post mortem was the mandibular incisor. Other findings included apical infections, which were detected clinically in 3% of the teeth.

    King Olaf's men?: Contextualizing Viking burials at S:t Olofsholm, Gotland, Sweden2023Ingår i: International journal of osteoarchaeology, ISSN 1047-482X, E-ISSN 1099-1212, Vol. 33, nr 5, s. 802-815Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The discovery of burials at S:t Olofsholm, a site associated with the Saint Olaf cult on Gotland in Sweden, has enabled a bioarchaeological contextualization of medieval legends and sagas in conjunction with the archaelogical record. This study seeks to illuminate who were buried at S:t Olofsholm, through a biocultural lens, and whether these burials can be linked to folklore and sagas associated with the site. Five burials of possibly six individuals (cal. AD 980-1270) were assessed macroscopically and through stable isotope analysis (delta C-13, delta N-15, delta S-34, Sr-87/Sr-86, and delta O-18) of incremental dentine, bulk enamel, and bone samples. Sagas and legends associated with S:t Olofsholm mention episodes of conflict and contact involving King Olaf Haraldsson of Norway (later canonized as Saint Olaf), Gutes and Icelanders, and travels between Norway and Kyiv Rus. Two (or three) burials show signs of violent deaths, including evidence of sharp force trauma and burning. Isotope analyses indicate local and non-local signals, with possible links to southern Scandinavia, Britain, Iceland, the Baltics, and Kyiv Rus. In general, the evidence neither challenges nor confirms the legends and sagas associated with S:t Olofsholm. Instead, the findings illustrate the site's function as an early Christian place of worship within a wider Viking world that was characterized by travel and contact across the Baltic Sea, Scandinavia, and beyond. The burials at S:t Olofsholm are likely to be non-normative as indicated by their place of interment and the violent cause of death of most individuals.

    Pick the Right Pocket. Sub-sampling of Bone Sections to Investigate Diagenesis and DNA Preservation2017Ingår i: International journal of osteoarchaeology, ISSN 1047-482X, E-ISSN 1099-1212, Vol. 27, nr 3, s. 365-374Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Many archaeological bones display a heterogeneous degradation pattern. Highly degraded bones could contain pockets of well-preserved bone, harbouring good quality DNA. This dichotomy may explain why the relationships between global bone preservation parameters such as histological integrity, bone mineral crystallinity or collagen yield, and bulk DNA preservation/amplification success rate have been found to be at best, weak to moderate. In this pilot study, we explore whether or not a more localised approach will highlight a stronger relationship between diagenetic parameters and DNA preservation. This study includes a detailed histological characterisation of bone diagenesis in sub-areas of three bone samples. Regions of the same bone, which displayed differential degrees of preservation or type of diagenesis were sampled for further analysis and both genetic (small scale Illumina MiSeq sequencing) and chemical (Fourier-transform infrared spectrometric analysis) analyses were performed. The aim was to investigate how bone diagenetic processes relate to DNA preservation at a higher resolution than in previous studies. This is key in order to improve DNA analytical success rates. The expected relationship between bone and DNA preservation (retrieved endogenous DNA) was observed and the results corroborate previous work that DNA preservation is linked to the integrity of bone collagen and mineral. The results further suggest that non-biological diagenetic alterations such as etching and the presence of mineral infiltrations and inclusions have a negative effect on DNA preservation/extraction.
