Abstract [en]

Sex identification of skeletal remains based on morphology is a common practice in Zooarchaeology. Knowledge of the sex distribution of slaughtered or hunted animals may help in the interpretation of e.g. hunting or breeding strategies. Here we investigate and evaluate several osteometric criteria used to assess sex of cattle (Bos taurus) metapodia using molecular sex identification as a control of the metric data. The bone assemblage used to assess these new criteria derives from the Eketorp ringfort in the southern parts of Öland Island in Sweden. One hundred metapodia were selected for molecular analysis of sex and we were able to genetically identify the sex of 76 of these elements. The combined results of the molecular and osteometric analyses confirm a significant size difference between females and males for several measurements for both metacarpals (Mc) and metatarsals (Mt). Our results show that some measurements are applicable for metapodials. These measurements include the slenderness indices such as the Mennerich’s index 1 and 3, as well as the distal breadth (Bd), the breadth between the articular crests (Bcr), and the maximum breadth of the lateral trochlea (BFdl). We show that they can be used for sexing of both metacarpals and metatarsals. The latter measurements offer an opportunity to study fragmented elements and thus a higher number of elements may be utilized for morphological sexing of archaeological bones. Size comparisons of Mc and Mt may also aid in the separation of bulls and oxen.

Abstract [en]

Central to this thesis is the relationship between animal husbandry practices and the associated pathological conditions. Since bone elements from the extremities are subjected to abnormal load when animals are put to hard work this research aims to go further and interpret the prevalence of varying lesions and their connection with animal husbandry by using methods such as osteometric analysis, conventional radiograpic and bone mineral study, as well as incorporated molecular analysis.

The results show that approximately 15% of the cattle extremities at Eketorp ringfort had some kind of skeletal lesion. Cattle metatarsals exhibited a higher frequency of lesions than metacarpals. Skeletal lesions connected to draught use were more frequently recorded on bone elements from male than from female cattle. The anterior phalanges 1-2 had a higher occurence of lesions than the posterior elements. In addition, there was a significant correlation between larger sized animals and lesions. Osteological measurements were also investigated using molecular sex identification. Several measurements in both fragmented and complete metapodials proved useful in separating cows from oxen or bulls.

Conventional radiographics were used on cattle metapodials from Eketorp ringfort to investigate the age structure in slaughtered cattle over 3 years of age. In phase III more male cattle were slaughtered before 8 years of age which could reflect the character of the site. The bone density analysis showed that modern cattle metapodials had higher values than the archaeological specimens which made intepretation of post-depositional changes problematic. The molecular analysis did not show any selected breed or specific type of animal. All but two of the Eketorp cattle belonged to haplogroup Y2 which is common in Southern Europe. The Y1 haplogroup (one in phase II and one in phase III) is common in Western and Northern Europe. The results point to that the Ölandic cattle population was homogeneous over time. The results from thirty-four bone elements show that twenty-five bones belonged to animals with red or light coat coloration and nine of uncertain, possibly partly black colour.
