We present results of starch analysis of archaeological deposits from Pitcairn Island. High concentrations of starch grains preserved in cell membranes, and xylem tracheary elements, consistent with introduced Colocasia esculenta (taro) were found. Because of limited age control, we are uncertain if the microfossils are prehistoric. Problems associated with identifying taxa with small starch grains in extractions from weathered deposits are highlighted.  相似文献

Recent multidisciplinary investigations document an independent emergence of agriculture at Kuk Swamp in the highlands of Papua New Guinea. In this paper we report preliminary usewear analysis and details of prehistoric use of stone tools for processing starchy food and other plants at Kuk Swamp. Morphological diagnostics for starch granules are reported for two potentially significant economic species, taro (Colocasia esculenta) and yam (Dioscorea sp.), following comparisons between prehistoric and botanical reference specimens. Usewear and residue analyses of starch granules indicate that both these species were processed on the wetland margin during the early and mid Holocene. We argue that processing of taro and yam commences by at least 10,200 calibrated years before present (cal BP), although the taro and yam starch granules do not permit us to distinguish between wild or cultivated forms. From at least 6950 to 6440 cal BP the processing of taro, yam and other plants indicates that they are likely to have been integrated into cultivation practices on the wetland edge.  相似文献

To discern the presence of two anatomically close species within an archaeological assemblage is always a problem for the analyst. A particularly interesting case is the distinction between the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus), which is often determined using non-rigorous criteria and producing results that must be regarded with caution. Classical methods for separating these two species and determining sexual dimorphism, and eventually the sex ratio, such as analyses using uni- and bivariate plots, are based on arbitrarily fixed limits between sexes. In this text, a more robust statistical method termed mixture analysis (MA) is used to determine the species of limb bones from foxes. First, the MA is applied to a sample of each species using metric data taken from a collection of present-day fox skeletons. Afterwards, the MA is applied to archaeological samples dated to the Dorset period and retrieved from the Tayara site (near Salluit, South Hudson Strait, Nunavik). The results clearly demonstrate that the greatest length (GL) of long bones, especially the humerus and tibia, is the best measurement for distinguishing the species, followed by the distal breadth and the proximal breadth; and that GL is better suited for sexing foxes. The results of MA applied to the Tayara site collection lead to the conclusion that the red fox is present along with the arctic fox among the assemblage, and that there is no fox body size change during the last two millennia in the Eastern Arctic.  相似文献

Analysis of plant microfossils (pollen, phytoliths, starch grains and xylem cells) was carried out on 12 soil samples from a variety of pre-contact archaeological features in South Kona within a portion of what has been termed the Kona Field System, on the Island of Hawaii. The oldest radiocarbon ages of the sampled deposits are 1300–1625 AD and 1310–1470 AD. The pollen and phytolith evidence suggests a change from more to less trees and shrubs in the area as a result of human activity. We found phytoliths of banana (Musa sp.) leaves in most and starch grains and xylem cells of tuberous roots of c.f. sweet potato (Ipomoea batatas) in all of the samples, suggesting that the sampled features were associated with these crops and that both crops were cultivated intensively within the study area. Higher concentrations (volumetric) of starch and xylem in samples from older deposits suggest that cultivation was more intensive then. The apparent absence of starch and xylem remains of other tuberous crops archaeologically identified elsewhere in Polynesia suggests that tuberous cropping within the study area was mono-specific.  相似文献

We present results of phytolith analysis of deposits from three prehistoric settlement sites in Vanuatu: the small islands of Vao and Uripiv off the north east coast of the main island of Malekula and at Mafilau on the west coast of Epi Island. Samples from Vao Island coarsely encompass the period from Lapita times (c. 3000 BP) to the present. The data from this site suggest deforestation by people, with a decrease in palms and increase in grasses. The data from the three sites show evidence of an introduced cultigen during different prehistoric periods. Banana (Musa) phytoliths were found in one recent Vao layer (500 BP-present) and in Mafilau layers, the latter representing the immediate post-Lapita period (c. 2800–2500 BP). This phytolith type was also found at Uripiv in Lapita layers (c. 3000–2700 BP). Banana phytoliths are diagnostic so their presence in archaeological deposits in Remote Oceania, outside their natural distribution, provides secure evidence of cultivation. This demonstrates the potential of this line of evidence for identifying both the cultigens transported by early colonists and subsequent plant introductions. The data provide the first direct evidence of banana cultivation at a Lapita site in Remote Oceania and support the contention that horticulture was an integral part of the Lapita Cultural Complex.  相似文献

A review of archaeobotanical data, together with new, still unpublished data, from Roman sites in conventus Bracaraugustanus suggests the Romanization of the northwest Iberia brought little changes to the agricultural strategies of local communities in indigenous-type settlements. The main crops remain the same as in the Iron Age: Triticum aestivum/durum, Panicum miliaceum, Hordeum vulgare subsp. vulgare, Triticum turgidum subsp. dicoccum and T. aestivum subsp. spelta, Avena and Vicia faba. The first secure reference for the cultivation of Secale cereale in the region comes from a Roman context, suggesting that it was introduced in this period, although it probably remained a minor crop.  相似文献

Analysis of starch granules, phytoliths, and plant macrofossils from archaeological features and carbonized food residue provides important new insight into the extent of prehistoric maize (Zea mays) consumption on the North American Great Plains. These data suggest that consumption of maize, and probably other cultigens, was widespread on the eastern Canadian Prairies between approximately AD 1000 and 1600. Domesticated plants may have been grown locally, acquired through trade, or transported into the region following dispersal of family groups from horticultural villages located elsewhere. However, the lack of strong artifactual evidence of gardening, and the small-scale nature of sites on the eastern Canadian Prairies indicate that local horticulture, if practiced, was non-intensive.  相似文献

Ustrina are incineration funerary structures that are relatively common in Roman age cemeteries. Salvage excavations at Encosta de Sant'Ana (Lisbon, Portugal) in 2002 brought to light a part of the necropolis of the Roman town of Olisipo, including some ustrina. One of them, designated Burial 1 during fieldwork, is analyzed here from a geoarchaeological viewpoint to understand the formation processes of such an archaeological feature, namely its construction technique, use and function. The study of site context and subsurface pedofeatures, and the application of archaeological soil micromorphology, revealed that the ustrinum was constructed digging a hollow in bedrock and building a mud-brick ridge around it, with raw material taken from the local bedrock. The structure was used at various times and remodelled at least once, and its base was not always thoroughly cleaned – according to the custom called “pars pro toto” by Roman authors – and probably left open when not in use.  相似文献

This paper refines current methods for aging mountain gazelle (Gazella gazella), one of the most common species hunted by prehistoric humans in the southern Levant. Most importantly, we present a new tooth wear scheme for aging the lower deciduous fourth premolar (dP4), the lower permanent molars (M1, M2, M3) and the lower fourth premolar (P4) of the gazelle. Broader wear stages for complete mandibles and individual teeth and bone fusion stages are also provided. Finally, a comparison of the tooth wear and bone fusion data indicates that the two methods can be linked at the important transition when a gazelle reaches adulthood (ca. 18 months of age). The completion of the fusion of the gazelle skeleton corresponds directly to the replacement of the dP4 by the P4 and the beginning of wear of the M3. The coincidence of these aging indicators allows for direct comparison of gazelle bone fusion and tooth wear data.  相似文献

The water vole, genus Arvicola, is characterised by a broad geographic distribution throughout Europe and is widespread during the late Middle and Upper Pleistocene. This genus is used as a major biostratigraphic tool within the Quaternary. Specific determinations using the Schmelzband-Differenzierung-Quotient or SDQ have identified many chronospecies within the fossil species Arvicola cantiana (Hinton, 1910). As SDQ calculation remains limited, this study reappraises the Arvicola genus in terms of morphodiversity and morphospace using outline analysis which takes into account the tooth as a whole. Outline analysis suggests that one single species of Arvicola, A. cantiana, was present during the Pleistocene. This species shows great variability with no trends or patterns in morphospace. Thus, these results call into question the reliability of SDQ for specific determinations and throw doubt on the biochronological framework based on Arvicola.  相似文献

The management and conservation of animal species should be based upon a long-term analysis that considers its geographical distribution and feeding patterns. The study of carbon and nitrogen stable isotopes on skeletal remains provides a quantitative approach to the paleodietary reconstructions and constitutes a potent tool for comparing behavioral aspects of the fauna. In this paper we present the first set of isotopic values for modern and archaeological samples of Huemul (Hippocamelus bisulcus) from the forests of Central-western Patagonia, Chile. Contrary to initial expectations, our analysis indicates that there is no evidence of an important incidence of the canopy effect on the δ13Ccollagen values, which we suggest is due to an ecological selection that drives the huemul to focus its predation on open sectors within the forest. On the other hand, a wide range of δ15Ncollagen values for huemul was verified. This could reflect the N impoverishment of the forest soils and provide an interesting ecological indicator. The long-term information offered by the archaeological record provides the necessary context for decision-making conducive towards the preservation of Hippocamelus bisulcus in Patagonia.  相似文献

Isotopic analyses of incrementally developed dental tissues can be used to reveal patterns of movement and diet in animals. However, the suitability of these methods for the reconstruction of herd movements has not yet been demonstrated. Inter-individual behavioural and isotopic variability at the herd scale, and the implications for archaeological and palaeocological applications, can only be demonstrated through the testing of modern animals. In this pilot study, dual-element isotopic profiles were created from incrementally developed dental tissues of five individuals selected from a modern herd of migratory Alaskan caribou (Rangifer tarandus granti). Enamel from second and third molars from the individuals was sequentially sampled in order to reconstruct time-series isotopic profiles. Variation in the strontium (87Sr/86Sr) and oxygen (δ18OCARB) isotope ratios of sequentially sampled enamel were compared to documented herd movement patterns and local geological and environmental conditions. Four individuals displayed the same general trends, although absolute isotopic values varied. One individual displays a very different trend and may represent a behavioural outlier or an immigrant from a semi-domesticated reindeer herd. The implications of this study to herd movement reconstruction in the past are discussed.  相似文献

The fruit (pods) of Prosopis (Fabaceae) are frequently recovered from pre-Hispanic Argentinian archaeological sites, suggesting that this genus was of importance in ancient economies in this region. Yet it is only recently that archaeobotanists have begun to carry out systematic research into this genus. Therefore many questions remain to be addressed concerning the food value of Prosopis fruit, and its potential contribution. This paper examines starch from the pods of two species, Prosopis flexuosa and Prosopis chilensis, for the purposes of describing and classifying their morphological features and biometrical parameters. Pods of both species were gathered from two extremes (northern and southern) of the Hualfín Valley, Catamarca, Argentina. Starch abundance is estimated and compared with that of Zea mays, an economically important plant with high concentrations of starch. This paper reveals that Prosopis pods contain very low amounts of starch compared to starch-rich edible species. Despite this, the recovery of Prosopis starch grains can be successfully used to assess archaeological tool uses. Prosopis starch grains were found to be highly variable in shape. Grain size ranged between 10 and 20 μm. Granule irregularity and the high birefringence under polarized light are two of the most important diagnostic features. No significant statistical differences were found in the structure (morphology, size and hilum) of the starch of the same species from both localities. Finally, the implications for the role of this plant in past societies are discussed.  相似文献

A set of ten Millefiori glass fragments dating from the 17th century, originated from archaeological excavations carried out at the Monastery of Sta. Clara-a-Velha (Coimbra, Portugal), were characterized by X-ray electron probe microanalysis (EPMA), Raman microscopy and UV–Visible absorption spectroscopy. All glasses are of soda-lime-silica type. The use of coastal plant ash is suggested by the relatively high content of MgO, K2O and P2O5, as well as by the presence of chlorine. Tin oxide or calcium antimonate were the opacifiers used in the opaque glasses, cobalt in the blue glasses, copper in the turquoise glasses, iron in the yellow and greenish glasses, and iron and copper were found in the opaque red and aventurine glasses. Based on the concentrations of alumina and silica four different sources of silica were identified, allowing the classification of the glasses into the following compositional groups: low alumina (<2 wt%), which includes a sub-group of cristallo samples with SiO2 > 70 wt%, medium alumina (2–3 wt%), high alumina (3–6 wt%) and very high alumina (>6 wt%). Comparison with genuine Venetian and façon-de-Venise compositions showed that two fragments are of Venetian production, one of Venetian or Spanish production and the remaining are of unknown provenance. In two fragments the glass of the decoration is probably Venetian or Spanish but the glass used in the body is also of unknown provenance.  相似文献

Rodent prey remains recovered from Geoffroy's cat (Leopardus geoffroyi) scats were analyzed in order to identify taphonomic features produced by this predator. The analysis includes a year-long sampling discriminated by the seasons. Modifications produced by digestion are heavy. Taphonomic variables in samples discriminated by the seasons did not show major differences with respect to the total sample; thus, scats collected in any season clearly show the modifications on the bones of prey rodents made by Geoffroy's cats. The results presented here and its interpretation could be extrapolated to an analysis of zooarchaeological or paleontological assemblages.  相似文献

Fruits glued on two wooden tubs were discovered in the Yanghai Tombs of Xinjiang, China. The tombs were built about 2500 years ago. Morphological and anatomical features of fruits show them to be Lithospermum officinale L. The fruits were assembled into obtriangular shapes along the tub mouth. This is a report of people using plant fruits for decorative purposes 2500 years before present.  相似文献

Although they are often subjected to critical scrutiny, formal geopolitical practices have rarely been put on trial. One exception is the case of Gudmund Hatt (1884-1960), professor of human geography at Copenhagen University from 1929 to 1947, who was found guilty of “dishonorable national conduct” for his geopolitics during the German occupation. As a contribution to the critical history of geopolitical traditions, this article investigates Hatt as an example of a small-state geopolitician. Particular attention is given to his view of geopolitics as a practice and as an essentially material struggle for Livsrum (living space), and what this made him infer for the great powers and for small-state Denmark. Hatt’s geopolitical ideas had many parallels to those of his great-power contemporaries, but in important respects, his analyses also differed from traditional geopolitics. It is argued that, to a significant degree, this difference is related to the fact that Hatt narrated geographies of world politics from a small and exposed state with few territorial ambitions. This made him emphasize economic relations, efficiency rather than territorial size, and the geopolitical role of the Danish Folk (i.e., the nation). Hatt’s position as a peripheral observer to the geopolitical mainstream may also explain his understanding of geopolitics and living-space politics as practices pursued by all great powers.  相似文献

This paper presents results of contextual, technological, use-wear and residue analyses of body ornaments from two Late Mesolithic burials recently excavated at the site of Vlasac in the Danube Gorges of the central Balkans. Common to both burials are ornaments made from modified and unmodified carp (Cyprinidae sp.) pharyngeal ‘teeth’ along with Cyclope neritea marine gastropods. Experimental and low and high magnification use-wear approaches have been employed in reconstructing the way these ornaments were made and used. The precise contextual distribution of these ornaments has been recorded for the first time. The two examined burials exhibit a number of similarities, particularly in the way ornaments were placed in relation to the body. Both burials are also contemporaneous, dated to the mid-7th millennium BC. Implications of these findings for Mesolithic foragers' corporeal symbolism, group identity and regional and long-distance acquisition networks are briefly examined.  相似文献

Hyena taphonomy is of great importance to studies of hominid evolution, since these carnivore taxa have the highest potential both to produce large osseous assemblages and to modify existing hominid-accumulated assemblages throughout the Old World. The three extant hyena species (brown: Parahyaena brunnea; striped: Hyaena hyaena; and spotted: Crocuta crocuta) are all significant bone collectors and modifiers. Spotted hyenas generally have the lowest potential to accumulate osseous remains, and the rate of accumulation varies based upon the type of den. The present research examines the remains accumulated by spotted hyenas in Masai Mara Cave, Masai Mara National Reserve, Kenya. The contents of this den were collected twice by the authors, with an 11-year span interceding. The taphonomic signatures of spotted hyena interaction with bone are presented, including species and skeletal element representation, breakage patterns, tooth marks, tooth puncture, edge polish, and gastric corrosion. Other taphonomic factors examined include rodent gnawing and weathering stage. The cave den assemblage was accumulated at a rate of 30.4 identified specimens and a minimum of 4.1 prey individuals per year. In addition, the osseous remains accumulated by spotted hyenas at multiple burrow dens within the Reserve were examined for taxonomic representation and multiple taphonomic parameters. Rates of accumulation at this type of den tend to be very low, due to differential usage by spotted hyenas and the more ephemeral nature of earthen dens.  相似文献
