Caries prevalence and other dental pathological conditions in Vikings from Varnhem, Sweden.

In a late Swedish Viking Age population dating from around 10th-12th century AD, the prevalence, distribution and location of dental caries were studied. Tooth wear, other dental pathology and anatomical variations were identified and recorded clinically and radiographically. A total of 3293 teeth were analyzed from 171 individuals with complete and partial dentitions, of which 133 were permanent and 38 deciduous/mixed dentition.

The prelude to industrial whaling: identifying the targets of ancient European whaling using zooarchaeology and collagen mass-peptide fingerprinting.

Taxonomic identification of whale bones found during archaeological excavations is problematic due to their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of possible early whaling activities. To overcome this challenge, we performed zooarchaeology by mass spectrometry on an unprecedented 719 archaeological and palaeontological specimens of probable whale bone from Atlantic European contexts, predominantly dating from 3500 BCE to the eighteenth century CE.

Dental markers of biocultural sex differences in an early modern population from Gothenburg, Sweden: caries and other oral pathologies.

Background: With the aim to study dental pathological lesions in an early Swedish modern population, with special reference to sex variances of dental caries, the prevalence and distribution of dental caries and tooth wear were determined in complete and partial human dentitions from an early modern-time city graveyard (1500-1620) excavated in Gamlestaden, Gothenburg, Sweden.

Methods: Partial and complete dentitions were examined through visual inspection and using a dental probe. Pathologies were studied, evaluated and presented by teeth and alveoli.

Population genomics of the Viking world.

The maritime expansion of Scandinavian populations during the Viking Age (about AD 750-1050) was a far-flung transformation in world history. Here we sequenced the genomes of 442 humans from archaeological sites across Europe and Greenland (to a median depth of about 1×) to understand the global influence of this expansion. We find the Viking period involved gene flow into Scandinavia from the south and east.

Finding the founder of Stockholm - a kinship study based on Y-chromosomal, autosomal and mitochondrial DNA.

Historical records claim that Birger Magnusson (died 1266), famous regent of Sweden and the founder of Stockholm, was buried in Varnhem Abbey in Västergötland. After being lost for centuries, his putative grave was rediscovered during restoration work in the 1920s. Morphological analyses of the three individuals in the grave concluded that the older male, the female and the younger male found in the grave were likely to be Birger, his second wife Mechtild of Holstein and his son Erik from a previous marriage.
