Long voyages required serious logistics. Onboard meat supplies were analysed from animal remains found in shipwrecks. Here we present a bibliographical synthesis of results obtained from the study of 33 published shipwrecks in order to assess the importance of the presence of animals aboard and to underline questions still unanswered. © 2011 The Author  相似文献

Ancient preserved molecules offer the opportunity of gaining a deeper knowledge on their biological past. However, the development of a proteomic workflow remains a challenge. The analysis of fossils must involve a low quantity of material to avoid damaging the samples. In this study an enhanced proteomic protocol was applied to 5-milligram samples of about 130,000-year-old mammalian bones ranging from the end of the Middle Pleistocene up to the earlier Upper Pleistocene, excavated from Scladina Cave (Sclayn, Belgium). Using sequence homology with modern sequences, a biological classification was successfully achieved and the associated taxonomic ranks to each bone were identified consistently with the information gained from osteomorphological studies and palaeoenvironmental and palaeodietary data. Amino acid substitutions on collagens were identified, thus providing new information on extinct species sequences and helping in taxonomy-based clustering. Considering samples with no osteomorphological information, such as two fragments of bone retouchers, proteomics successfully identified the families providing paleontologists new information on these objects. Combining osteomorphology studies and amino acid variations identified by proteomics, one of the retouchers was potentially identified as belonging to the Ursus spelaeus species.  相似文献

Hyperostosis frontalis interna (HFI) is a benign bone lesion, which is asymptomatic for the most part and is manifested by the accretion of bone on the endocranial surface of the frontal bone. This type of lesion has been discussed in a multitude of publications since the 19th century. Although a consensus has yet to be reached as to its etiology, it would seem generally accepted that hormones play a role, which would explain the high frequency of this disorder among older and postmenopausal women. The objective of this study is to demonstrate the benefit of HFI diagnosis for identifying individuals (estimating their age and determining their sex) in the archeo-anthropological analysis of ancient cremation burial sites and in medicolegal investigations on burned human remains. Our sample consisted of 82 cremated individuals from the Roman Porta Nocera necropolis in Pompeii (1st century BC–1st century AD). After excluding juveniles under 15 years of age, as HFI primarily affects adult individuals, our sample was reduced to 71 individuals, and the prevalence of HFI was 15.5% (n = 11). A statistically significant difference is observed between women and men, and no individuals previously identified as male displayed HFI. Furthermore, 90.9% of the individuals displayed degenerative conditions in conjunction with HFI, showing a highly significant correlation of this lesion with signs of aging (chi-square 9.365; p = 0.01). Finally, this disorder boosted diagnostic performance in respect of determining sex, increasing the number of biologically sexed individuals from 46.5% to 53.5%. Therefore, we propose that the HFI diagnosis offers genuine added value in the identification of burned human remains.  相似文献

Lead concentrations were determined in ribs obtained from the Neolithic long barrow at Hazelton and compared with those in a series of modern bones. The mean lead concentration in the neolithic material was about two-and-a-half times less than the contemporary mean indicating that human activity has considerably increased the human body burden of lead.  相似文献

In this study, DNA was extracted from human bones recovered from a 2000-year-old archaeological site located in northern Kyushu in southwestern Japan. Part of the mitochondrial control region was amplified by a polymerase chain reaction. Mitochondrial DNA sequences determined from 55 individuals were classified into 16 different types. Comparing the location of the burial site and the sequence types, people buried at separate sites were shown to have different maternal lineages. Our palaeomolecular biological findings strengthen the opinion that social differentiation began during this period in Japan, a fact that is generally accepted among archaeologists. The results of this study show that intensive analysis of ancient DNA from archaeological sites is a useful tool for investigating the social systems of vanished populations.  相似文献

The main aim of this study is to try to see if, despite the diagenetic changes undergone by the fossil bones buried in Venta Micena (Orce, Spain), the concentration of trace elements permits the differentiation of particular groups. It is possible that some chemical elements allow us to identify different dietary groups in accord with their archaeological context. Different multivariant methods—correlation, principal component analysis and cluster analysis—were applied to the data, and in all cases the results show that two elements (Ba and Zn) seem able to discriminate between groups with different diets. In this sense, diagenesis cannot explain all the variability found in the concentrations of trace elements in fossils from the Orce region. © 1998 John Wiley & Sons, Ltd.  相似文献

Is bowing in long bones from an archaeological context representative of postmortem damage or genuine antemortem pathology? Bowing deformities (also known as traumatic bowing deformities, plastic bowing deformities, plastic bowing fractures and acute bowing fractures in the clinical literature) are true pathological entities that have only recently been recognized by clinicians. Bowing in long bones results from a force that exceeds the elastic properties of a given bone, producing a new plastic (bowing) response phase. These subtle deformities commonly affect the radii and ulnae in children and less frequently other tubular bones of the skeleton. Traumatic bowing should be considered as a possible diagnosis whenever abnormal curvature of a long bone is observed. This presentation illustrates two cases of traumatic bowing isolated from two ossuary populations from Ontario, Canada and addresses differential diagnostic concerns. © 1998 John Wiley & Sons, Ltd.  相似文献

The present study presents a method for predicting triggerfish body size (standard length and body mass) from bones recovered from archaeological sites. Regression equations were calculated from 42 fresh triggerfish. The following seven measurements were used as best predictors for body size based on the regression coefficients, reliability of the measurements and survivorship of the bones in archaeological material: width of ethmoid, width of vomer, width of first dorsal spine, width of dorsal postcleithrum, width of atlas, width of sixth vertebra, and greatest height of basal pterygiophore. These equations enabled us to assess the contribution of fish to the economy and aided us in identifying various fishing methods. © 1997 by John Wiley & Sons, Ltd. Int. J.

甲骨卜辞所见之巫者的医疗活动   总被引:2,自引:0,他引:2  
古代巫医不分,由于人类将疾病致因视为鬼魂作用,故以巫者充当人鬼间的中介,寄希望于巫术行医、安抚死神从而达到消除疾病的目的。正因基于此观念,医与巫、医疗与巫术、药物心理与巫术心理取得了自然的结合,求药及求巫两者皆统一于医疗活动之中。商代的医疗知识仍然处于中国医学的萌芽状态,具有迷信性质,常与巫教信仰交织在一起。即使如此,此时的巫医也开拓壮大了医学的先河。除利用药材之外。商人亦知运用针刺方法以治病,此种针砭医疗器具,在各地遗址时有发现。在医疗方面的巫术的具体活动,则主要包括二种:一为医疗巫术,二为逐疫除凶。  相似文献

山东沭河上游出土人骨的食性分析研究   总被引:5,自引:0,他引:5  
本研究通过对山东沭河上游大汶口文化晚期及春秋战国时期 2块人骨的碳、氮同位素分析和无机成分的锶、钡、钙等微量元素分析 ,恢复了当时人的食物结构。结论有以下两点 :1 由同位素分析可知 ,本地区贫民老百姓的食物在大汶口晚期时以C4植物为主 ,大约占 6 5 1 %的比例。此时期的食物结构存在贫富差异 ,富有者的食谱主要以C3植物为主 ,大约占 6 6 4 %的比例。 2 通过对小朱家村遗址出土的 1块人骨样品的微量元素分析 ,反映出同位素分析所表明的C3植物 ,除了少量种植的稻米外 ,可能还包括胡桃属、榛属、栗属、豆科等采集植物。  相似文献
