Using incremental patterns in tooth cementum is a powerful tool for age assessment. Recent developments have shown that the method has a large potential as an indicator of the season of death of the individual in question. In this paper, the results of a study comparing thin sections of teeth of the modern Hardangervidda reindeer population to those of Iron Age, eleventh, and thirteenth century reindeer hunting stations from the same area are presented. The tooth wear stages were compared to the actual age of the individual (based on the number of incremental lines and the age at eruption). It was established that in the studied reindeer populations wear stages sometimes result in too low an age estimate. Having identified the start of the period of deposition for rest lines in the modern reindeer population as early autumn and winter, analysis of the outermost layer in the tooth cementum at the archaeological sites points to a prolonged hunting season in the thirteenth century, while in the earlier phases hunters were probably present on fewer and shorter visits.  相似文献

In 2010–11 a pedestrian survey of the western end of Wadi al‐Hijr in northern Oman identified 1507 archaeological features in a 124 km2 area. Data were collected on each feature's architectural characteristics, associated artefact assemblages, topographic and environmental locations, condition of remains, and relations to other archaeological features. The majority of datable features belong to the third millennium BC and divide unequally between the Hafit and Umm an‐Nar periods. While the majority of these third‐millennium BC features were tombs, other feature types were identified, including towers, settlements, quarries, dams, enclosures, and possible platforms. Third‐millennium BC features were organised into clusters and ranged considerably in size, from a few features to several hundred. All of the clusters established during the Hafit period were maintained in the Umm an‐Nar period, suggesting a continuity throughout the third millennium. Some preliminary hypotheses regarding settlement patterns are suggested.  相似文献

One of the main factors involved in entheseal changes (EC) aetiology may be related to the physiological limits of biomechanical loading fixed during bone development, such that higher load during childhood and the adolescent growth spurt leads to a lower frequency of EC during adulthood. In this sense, it is possible that ECs may be related to overloading beyond an individual's normal physiological limits as established during childhood and adolescence. This meta‐analysis tested this aetiological possibility by studying the influence of terrain on the entheses of the lower extremities. The hypothesis is that individuals who inhabited rugged terrain have lower EC than those living in flat terrain. This is because biomechanical loads associated with rugged terrain will lead to a higher normal capacity (defined during skeletal development) mitigating the probability of overloading compared to those living in flat terrain who will therefore have a higher frequency of ECs. To test this, papers reporting EC frequencies in the lower limbs were analysed alongside the local terrain. Terrain was defined into two categories: flat or rugged based on altimetry profile, i.e. the average elevation gains and losses along four specific paths (North‐South, East‐West, Northwest‐Southeast, Southwest‐Northeast). Odds ratios were calculated to compare rugged and flat terrain. The overall results are consistent with the hypothesis that overloading is a factor in EC aetiology. However, when the analysis is conducted by sex and side, this general trend does not always occur. Limitations such as the lack of standardized age ranges could be affecting the outcome, i.e. older individuals have a higher frequency of ECs. The findings of this analysis suggest that the theoretical assumptions associated with the cause of ECs require further testing and evaluation. Copyright © 2017 John Wiley & Sons, Ltd.  相似文献

This paper presents a revised version of the Coimbra method for recording fibrocartilaginous entheses. The method itself is the only biologically appropriate recording method for fibrocartilaginous entheses that scores features separately, thereby ensuring that the aetiology of individual features can be studied. The method divides the enthesis into two zones, scoring the relevant features in each zone. These features represent either bone formation or bone destruction and include erosive lesions, fine and macro‐porosity, and cavitations. The revised method includes a new feature, textural change, which is scored as absent or present when it involves 50% or more of the surface. All other features are now scored as zero (absent), one or two with the higher score representing greater expression of the feature. This change in scoring has led to the reduction of inter‐observer error with approximately 80% agreement for overall feature scores for both the common extensor origin and subscapularis insertion. The simplification of the scores and the reduction in inter‐observer error mean that the method is now recommended for widespread use. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

ABSTRACT

The interpretative power of quantitative intra-site spatial analysis has long been recognised by archaeologists. On the contrary, very few ethnoarchaeological works have engaged with the statistical analysis of intra-site pattern of artefacts and ecofacts. Nonetheless, ethnoarchaeology is uniquely placed to guide and assist in the identification of sound techniques and in the development of the methodology of analysis. The possibility to directly connect the distribution of the proxies under study with the activity that generated such distribution, provide the means of fine-tuning the tools we use for identifying these patterns in the archaeological record. As a consequence, archaeological methodology and interpretation both benefit from the application of improved methodologies. In this paper we review some of the most common techniques used to analyse activity areas and we provide examples of the application of such techniques to ethnoarchaeological contexts. The aim is to assess how archaeology can benefit from the intra-site spatial analysis of ethnoarchaeological contexts.  相似文献

Musculoskeletal stress markers (MSM) have been used to reconstruct activity patterns and labour intensity of past populations. Age and size have been found to correlate with MSM, and these aspects should be considered in activity reconstructions. The aim of this study was to find out the nature and the effects of labour intensity, age and size on MSM. Study material were skeletons (N = 108) of individuals of known age, sex and occupation housed at the Natural History Museum, Finland. MSM were scored for Pectoralis major, Deltoid, Teres major and Biceps brachii. These scores were combined to reflect total activity of an individual. Geometric mean of humeral measurements was used as a size indicator and radial tuberosity size was used as a muscle size indicator. Factors explaining MSM were studied using ANCOVA. This included age, size, muscle size, sex, labour intensity, and their interactions. Age and muscle size were the most significant factors explaining MSM, where muscle attachment areas and MSM grow with advancing age. Muscle attachment areas and skeletal frame size were also found to correlate. Least squares regression parameter estimates were used to study the effects of labour intensity, sex and side on MSM. It was found that in early life scores are higher in heavy labour group, but there is less age‐related increase in these scores. This could mean that bone is unable to respond to heavy and continuous loading with surface structure. Therefore labour intensity cannot be reliably recorded in old individuals. Also age and size (as reflected in muscle attachment area) affect MSM and these aspects should be considered before making assumptions on labour intensity.

经济行为与环境变化:清前期台湾野生鹿消失探析   总被引:3,自引:0,他引:3  
鹿曾经是台湾数量最庞大的野生动物群之一。明末以来,随着台湾贸易交流的活跃,鹿成为大宗出口商品,土著居民由原先捕鹿作为民生用品逐渐发展至为市场服务;清前期大陆移民入台的农业垦殖又破坏了鹿原有的生态环境。人类经济行为引发的环境变化,最终导致了野生鹿在台湾渐趋消失。  相似文献
