Starch grains from 31 modern samples of millets derived from the seeds of 7 species within the genus Setaria and 2 species within the genus Panicum were analyzed to determine diagnostic morphological characteristics. Ancient starch grains recovered from a sample of broomcorn millet (Panicum miliaceum) excavated from the Cishan site (10.0-7.6 cal yr BP) in the North China Plain were then subjected to the same analyses to determine the differences in morphologies, if any, between modern and ancient samples. The data indicate that morphological features, and particularly surface and fissure features, will allow for solid identifications of ancient millet starches, while size classes will be helpful, but will not be dependable taxonomic indicators.  相似文献

Plant residues recovered from prehistoric stone artifacts can be used to help explain tool function and plant use. At the Changning site in Qinghai Province, Northwest China, dating from 4000 yr BP, we examined starch granules extracted from three slate stone knives. A total of 153 starch grains were retrieved from three stone knives, from which we identified starches from legumes, the Triticeae tribe, foxtail millet (Setaria italica), broomcorn millet (Panicum miliaceum), roots and tubers. These results indicate that the stone knives may have been used for a variety of activities that included reaping grasses and food processing. The species of starch grains retrieved from the study sample reveal that diverse crops were cultivated at the Changning site 4000 years ago.  相似文献

Recent research involving starch grains recovered from archaeological contexts has highlighted the need for a review of the mechanisms and consequences of starch degradation specifically relevant to archaeology. This paper presents a review of the plant physiological and soil biochemical literature pertinent to the archaeological investigation of starch grains found as residues on artefacts and in archaeological sediments. Preservative and destructive factors affecting starch survival, including enzymes, clays, metals and soil properties, as well as differential degradation of starches of varying sizes and amylose content, were considered. The synthesis and character of chloroplast-formed ‘transitory’ starch grains, and the differentiation of these from ‘storage’ starches formed in tubers and seeds were also addressed. Findings of the review include the higher susceptibility of small starch grains to biotic degradation, and that protective mechanisms are provided to starch by both soil aggregates and artefact surfaces. These findings suggest that current reasoning which equates higher numbers of starch grains on an artefact than in associated sediments with the use of the artefact for processing starchy plants needs to be reconsidered. It is argued that an increased understanding of starch decomposition processes is necessary to accurately reconstruct both archaeological activities involving starchy plants and environmental change investigated through starch analysis.  相似文献

In a first region wide study, starch grains from human dental calculus from the pre-Columbian insular Caribbean (dating to ca. 350 B.C.–A.D. 1600) are used to identify important plant foods in the diet and to assess potential dietary differences related to age or sex. Results give important insights into pre-Columbian maize (Zea mays) consumption throughout the region, confirming recent studies that indicate that maize was more commonly consumed in the insular Caribbean than originally thought. No age or sex based differences in maize consumption were found. Furthermore, based on the results of new experiments regarding grinding and pressure damage to starch grains, it is clear that maize in the Caribbean was ground, baked and consumed as bread as was the case in large parts of the mainland. Based on our results we tentatively suggest maize consumption in the Caribbean was at least in some cases associated with feasting and ceremonial activities. The variety in other plant foods identified (mostly tuberous root crops) shows that the pre-Columbian inhabitants of the region consumed a broad spectrum, but locally variable diet in which a variety of root crops functioned as staple crops, including marunguey (Zamia sp.) and sweet potato (Ipomoea batatas). We found no indications for the traditionally assumed heavy reliance on manioc (Manihot esculenta) cultivation in the region.  相似文献

粮食贸易在民国时期江汉平原的农村经济中占有重要地位,粮商及粮商组织、粮食加工和运输、粮食价格、粮食集散和粮食存储等几个方面反映了民国时期江汉平原的粮食市场的基本情况。粮食贸易将大量的基层市场、少量中间市场和几个中心市场联系在一起,粮食价格的趋同性表明这个地区当时存在着完整的粮食贸易体系,但相关市场特征又表明这个市场是不完善的。  相似文献

Ancient Chinese dogs excavated at three archaeological sites and stored in the Institute of Vertebrate Paleontology and Paleoanthropology, Academia Sinica, were the object of this study (Xiawanggang site, 5000–6000 years BP; Keshengzhuang site, 3000–4000 years BP; Shangsunjia site, Bronze age). During these periods, there were large morphological variations in Chinese dogs beyond a single dog class, as with Jomon dogs. Dogs with a large ‘stop’ were already present in China but not in Japan. At the Keshengzhuang site, middle to large class dogs were also excavated. At least three types were confirmed within these dogs. In the aged dog in Xiawanggang, antemortem loss of many teeth was observed suggesting active use of the teeth and it is possible that this dog was used for hunting as were the Japanese Jomon dogs. © 1998 John Wiley & Sons, Ltd.  相似文献

本文根据考古学14C年代数据和考古遗存情况,结合高分辨率的地层和古气候研究资料,分析了河北及京津地区早中全新世文化的时空分布格局以及影响遗址分布的地貌和气候因素。该地区早中全新世文化时间序列为:早期新石器时代文化(10,000~8,800 yr BP)、新石器早中期之间的文化缺环(约8,800~7,300 yr BP)、7,300~6,500yr BP的磁山.兴隆洼.北福地一期三大文化系统并立发展时期以及6,500~6,000 yr BP的前仰韶文化时期。文化序列与气候序列对比发现:文化发展很大程度上受到气候条件的制约。从文化分布空间来看,具有如下特征:首先,早中全新世时期的文化分布在与当时海岸线平行的弧形地带上,这种分布格局与气候和地貌条件有关。在排除了地势高亢和海侵影响地区后,太行山东麓到古海岸线之间的弧形地带成为最佳选择。其次,从遗址分布高度来看,当时人仍居住在较高地貌面上,海侵及众多湖沼阻止了人类向东部平原腹地迈进的步伐。  相似文献

In combination, the analysis of carbonized food residue for stable C and N isotopes, elemental composition, and plant microfossils (phytoliths and starch granules) offers a powerful tool for understanding patterns of prehistoric maize (Zea mays) consumption in small-scale societies. Using this approach, we conclude that maize was more widely consumed in North America than previously suspected. Between ∼AD 700 and 1600, despite little or no archaeological evidence of gardening, corn was a widespread component of diet on the eastern Canadian prairies. This pattern, furthermore, extended into the adjacent boreal forest at about the same time. However, carbon (δ13C) and nitrogen (δ15N) values on food residue samples vary widely, suggesting significant overall dietary differences from one region to the next. Analysis of a subset of residue samples for elemental composition (using ICP-OES [inductively coupled plasma–optical emission spectrometry]) may help identify broad trends in the provenience of foods consumed at these sites.  相似文献

A total of 33 ancient glass beads unearthed from the Kizil reservoir cemetery and Wanquan cemetery in Xinjiang are studied using Raman spectroscopy, scanning electron microscopy with energy‐dispersive spectrometry (SEM–EDS) and other methods. The detailed study of the glassy matrices, the crystalline inclusions and the microstructural heterogeneities for these glass beads has revealed some valuable information to help in the understanding of their possible manufacturing technology and provenance. At least two different types of glass were present in the two cemeteries. For the first time, antimony‐based colourant/opacifier—for example, Pb2Sb2O7 or CaSb2O6—was systematically identified in some beads of plant‐ash type soda–lime glass dated to about 1000–500 bc . The limited number of potash glass beads from the Kizil reservoir cemetery, which were dated to about 500–300 bc , used tin oxide as an opacifier. The diverse resources of the soda–lime and potash glasses indicate the existence of a complex trade network between China and the West much earlier than the Western Han Dynasty.  相似文献

We report the results of an instrumental neutron activation analysis (INAA) undertaken on a regional sample of pottery from the Southern Nasca Region. The samples included specimens primarily from the Early Nasca (ca. A.D. 1–450) and Tiza (ca. A.D. 1000–1476) cultures from a total of 16 different prehispanic sites. The results of the analysis demonstrate centralized production of Early Nasca polychromes and decentralized production of pottery from the Tiza culture. The results of this analysis confirm previous conclusions about the organization of these two indigenous cultures of the south coast of Peru and support the hypothesis of an excess production of polychromes at the ceremonial center Cahuachi for Early Nasca, and multiple centers of production for the Tiza culture.  相似文献

Regional settlement datasets for the Yuncheng Basin and the Chifeng region are re-analyzed for comparison so as to reconstruct differing patterns of community development at local and supra-local scales. A methodological implication of this reanalysis is that comparing settlement areas and surface artifact densities between projects requires special attention to how the data were recorded so as to put them on the same measurement scale. The analytical approaches originally taken to reconstructing community organization in the two regions, while differing in several respects, are shown to produce highly compatible results, permitting a comparison of the two trajectories with a sound empirical foundation. Neolithic settlement began much earlier in Chifeng, but rates of demographic and community growth were extremely slow. In Yuncheng, early village growth was much more dramatic. Multiple chiefly districts of modest size emerged in both regions, but those of Yuncheng, despite their shorter developmental trajectory, had substantially larger populations. Their central settlements, in particular, grew to be much larger than those in Chifeng and the special activities carried out at these centers differed between the two regions. A poorly understood, but not contemporaneous, demographic disruption punctuated both sequences. It was followed by the emergence of political integration on a much larger scale in the Yuncheng Basin, focused on a single settlement an order of magnitude larger than its predecessors. In Chifeng, regional population soared far beyond previous levels, but political integration remained persistently small in scale.  相似文献

Although sparsely populated today, the Llanos de Mojos, Bolivia, sustained large sedentary societies in the Late Holocene (ca. 500 to 1400 AD). In order to gain insight into the subsistence of these people, we undertook macrobotanical and phytolith analyses of sediment samples, and starch grain and phytolith analyses of artifact residues, from four large habitation sites within this region. Macrobotanical remains show the presence of maize (Zea mays), squash (Cucurbita sp.), peanut (Arachis hypogaea), cotton (Gossypium sp.), and palm fruits (Arecaceae). Microbotanical results confirm the widespread use of maize at all sites, along with manioc (Manihot esculenta), squash, and yam (Dioscorea sp.). These integrated results present the first comprehensive archaeobotanical evidence of the diversity of plants cultivated, processed, and consumed, by the pre-Hispanic inhabitants of the Amazonian lowlands of Bolivia.  相似文献

In the context of the present study, we have conducted chemical and lead isotope analyses on twelve ancient glass samples unearthed from Chu tombs in Changde City, Hunan Province. The results of the chemical analysis of these samples show that all samples are PbO–BaO–SiO2 glasses, thus indicating that they are all traditional ancient Chinese glasses. The chemical results also suggest that all Bi wares may either share a common source or were produced according to similar recipes. In turn, the eye beads are different from the Bi wares for their distinct chemical composition. The chemical results indicate that silica, lead-bearing material, barium-bearing material, and sodium/lime-bearing material are the main independent components of the raw materials employed in the production of these glass wares.  相似文献

Size variation of Sus remains within and between sites is examined for the Neolithic sites in the Wei River valley in China. The coefficient of variation [V] for pig measurements at the sites of Wayaogou, Quanhucun and Jiangzhai was calculated, and we observed patterns that show evidence of two populations of different‐size pigs, supporting the likelihood that both wild and domestic pigs were present. Also, size reduction of pigs can be traced within the Neolithic‐early Bronze Age archaeo‐faunal sequence of the Wei River valley. This size reduction was accompanied by an increase of coefficients of variation through the Neolithic. Both of these trends were probably the consequences of pig domestication, and the morphometric differences probably provide evidence for the different stages of pig domestication in this region.

In order to identify the fibre material of the pall imprint excavated from the Peng‐state cemetery in Shanxi, biomass spectrometry was applied to determine the amino acid sequences of the residual protein extracted from the soil underneath the imprint. The sequences were searched against a standard protein sequence database. A well‐preserved silk pall sample from the Warring States Period was used as a comparative template. The protein extracted is identified as silk fibroin (Bombyx mori). This finding indicates that the extremely degraded pall was made of silk and that the deceased in the Peng‐state cemetery enjoyed high social status. In this way, a novel methodology, which is very promising in uncovering the origin of silk, could be initiated.  相似文献

This study is based on the SEM-EDS and LA-ICP-AES analyses of a sample of twenty-nine Tang sancai sherds unearthed from the Liquanfang site, Xi'an city. The results indicate that ceramics with yellowish bodies are calcareous and those with red bodies were made of ferruginous clays. The use of calcareous clay in Tang sancai bodies is otherwise unknown in Chinese history, which suggests that the technique of Tang sancai making at this site might have been influenced by ceramic technology from the Near East or Central Asia. The paper therefore argues that the traditional approach of treating calcareous clay as the main characteristic of pottery made in the ancient Near East or Central Asia is not necessarily accurate. It is likely that some calcareous Tang sancai ceramics were made in the capital city of the Tang dynasty.  相似文献
