We have made a multivariate morphometric study of the fossils ofMegantereonfrom the Apollonia-1 site at the Mygdonia Basin (Macedonia, Greece), using discriminant functions. Results obtained indicate that these specimens belong to the African speciesMegantereon whiteiBroom, which is also found in the Lower Pleistocene of Dmanisi (East Georgia, Caucasus) and Orce (Southern Spain). Morphofunctional studies ofM. whiteisuggest that this saber-toothed felid was an ambush predator with great killing capability in relation to its food requirements, thus leaving enough meat to be scavenged by both hyaenas and hominids.M. whiteimay have played an important ecological role making the first dispersal ofHomoto Eurasia the Lower Pleistocene possible.  相似文献

This is the first article that describes in detail the bird remains from the Gravettian mega-site Pavlov I in the Czech Republic. More than 1000 bird bones represent at least 19 taxa, of which the most numerous are tetraonids including black grouse (Tetrao tetrix), willow grouse (Lagopus lagopus) and ptarmigan (Lagopus muta), and ravens (Corvus corax). The archaeological and biological contexts indicate that most birds were hunted by people in the vicinity of the site, possibly with the help of knotted nets made from plant fibres. We suggest that ravens were killed while feeding on carcasses and/or food remains that may have been disposed of intentionally, and feathers may have been used for arrow fletching. Human-modified bones indicate that birds were used not only for food but also as raw material for tools and decoration. Although mammals were certainly more important in the subsistence of the Gravettian people, it is clear that birds played a role in their culture. The location of Pavlov I enlarges the explanatory scope of the Broad Spectrum Revolution hypothesis to include higher latitudes north of the Mediterranean.  相似文献

We conducted a paleo-parasitological study on soil samples from the ancient moat ruins of Weolseong palace, of the Silla Dynasty (BC 57–AD 935) of Korea. Based on the cultural remains found in the mud-soil layer, the layer was precipitated onto the floor of a moat between the 5th and 8th centuries AD. We found Trichuris trichiura eggs only in that mud-soil layer, whereas no parasite eggs were identified in the other archaeological strata of the ruins. As T. trichiura eggs are shed only in human feces, we speculated that palace toilet contents were continually drained into the moat; therefore, at a certain point in time after construction, the moat finally became a ditch around the palace. Structures in the stone embankments of the moat, possibly designed to make the water flow continuously in one direction, might reflect the Silla people's efforts to alleviate the ever-increasing problems inherent in a moat.  相似文献

Plant microfossil analysis was carried out on 12 soil samples from a variety of landscape features at three locations (100–250 m a.s.l.) along a 950 m transect at Te Niu, Easter Island. Pollen and phytolith assemblages were dominated by palms and ground ferns, and suggested disturbed forest. We identified pollen of bottle gourd (Lagenaria siceraria) and starch grains of the common yam (Dioscorea alata), sweet potato (Ipomoea batatas) and taro (Colocasia esculenta). The data suggest a mixed-crop, dryland production system at Te Niu dominated by yam and sweet potato, and supplemented by taro and bottle gourd. The data provide direct evidence of crop type and range, supporting the indirect evidence (topographic and landscape features, field and historical research, comparisons with elsewhere in the Pacific) that much of the rock covered landscape of Easter Island was used for intensive horticulture.  相似文献

The purpose of this article is to explain and discuss the essential operational characteristics of the technology of power (sensu Foucault) perpetrated on the internal frontiers with the Indians in nineteenth-century Argentina. The conquest and colonization of the Pampas took shape in the establishment of military camp structures placed to create a defensive cordon, known as “the Indian frontier line.” These constructions were fortlets defended by gaucho cavalry squadrons (know as Blandengues during the Spanish period, and then Guardias Nacionales after Argentinean Independence). This process is known in Argentinean historiography as “the conquest of the desert.” This particular technology of power existed in this historical context and operated at every social level, impacting strongly on the lower classes that inhabited the incorrectly named “desert.” Its implementation in the military field enabled the existence of an array of micro-powers that surrounded the gaucho, called vago y malentretenido—“a vagrant and lingerer”—and their women's lives. The army as institution was the locus of various forms of coercion and old forms of punishment (such as the stakes, whipping, and public executions) most of which affected peasants, nonresidents, itinerant workers, and the rural youth. This schema was adopted in different areas: in the enrolment and discipline of the gaucho soldiers, in life in the fortlet-prisons, and in the ritualism of power. The alternative chosen by soldiers to evade this technology of power and the fortlet-panopticons was escape through desertion. The utility of those observations is demonstrated, because an important part of the area of research of historical archaeology that has developed with the greatest impetus in Argentina has taken fortlets as its subject of study.  相似文献

Exploring the evolution of human cognition has been as methodologically problematic as it has been a vital area of study over the last couple of decades. In particular, the integration of archaeology and psychology, while fundamental to many such studies, has suffered from a difficulty by many researchers to effectively link models from the cognitive sciences with the archaeological data ( [Wynn, 2009] and [Wynn and Coolidge, 2010] ). In the current study one psychological process, proceduralization is used to examine the technological strategies that underpin the sequential nature of lithic core reduction. This is done via the application of sequential lithic information analysis (SLIA), a method developed by the author for the concurrent study of qualitative and quantitative sequential information. In the present context SLIA helps elucidate both the micro- and macro-level dynamics that underlie the reduction of a sample of Middle Paleolithic refitted Levallois cores from the site of Taramsa-1, Upper Egypt. The results of this study provide an explanation for the variability recognised within the Levallois technology and also speak to the existence of certain aspects of modern cognition by ca. 70,000 years before present.  相似文献

Genetic and archaeological evidence suggests that the majority of mummified ritual cats (Felis libyca subsp.) in ancient Egypt carried the t+ allele and exhibited the striped tabby phenotype. A few of these ritual cats, however, appear to be F. chaus subsp., most likely carried the Ta allele and were characterized by the Abyssinian phenotype. Several types of evidence suggest that the Ta allele first became fixed in a Felis sp. population in either southeast Asia or northeast Africa. A number of Felis subspecies appear to be plausible candidates for the population of Ta origin.  相似文献

One of the most prominent features of the Irish landscape is the great multitude of megalithic sites which date back to the Neolithic. In this paper, I will attempt to demonstrate that the understanding of these sites in Ireland can be enhanced by referencing the native tradition, including the Irish word for the sites, sí, and the sís powerful cultural tradition attested to throughout native Irish folklore, literature, onomastics, and traditional knowledge. In doing so, I will explore the difficulties and the potentials of interdisciplinary communication between archaeology and folkloristics, and the related issues regarding communication between official and unofficial discourses.  相似文献

Stable carbon (δ13C) and nitrogen (δ15N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ13C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle.  相似文献

In the following pages I consider how Descartes argues the thesis of a permanent, continuous and actual thinking represented by expressionscogito andsum cogitans. Of this thesis I only examine the reasoning leading to those expressions first and then reasoning upon the same, single expressions, I found the continuity of thinking breaks off when the mind, set aside the dubious or deceitful opinions, meets with the clear and distinct ideas, and when it meets with the succession of ideas. In both these cases there emerged a kind of interruption which should have prevented the philosopher from writing «cogito» and «sum cogitans», that is from making use of a verbal form just meaning an actual and continuous action.  相似文献

This is the first publication reporting systematic analytical research conducted on archaeological metals from Cuba. The main focus of the study consists of beads and small metal objects excavated at the cemetery of El Chorro de Maíta, which comprises some of the richest funerary deposits so far recovered on the island. Some comparative samples from the nearby site of Alcalá were also investigated, with an emphasis made on the manufacture, composition and origins of the different alloys. The resulting picture is that members of the social elite of the indigenous Taíno peoples were buried with beads made of placer gold exploited locally, gold–copper–silver pendants brought from continental South America and, above all, brass lacetags from European clothing that were perceived as sacred metals. The archaeometallurgical approach offers fresh insight into the relationships between Europeans and Taínos, and the impact of colonization on the indigenous customs, values and social structures.  相似文献

Florisbad, an open-air spring site with 7 m of strata, has yielded the type assemblage of Middle Stone Age (MSA) fauna, the cranium of an archaic hominid in 1932 and an extensive sequence of MSA artefacts in the 1980s. The cultural assemblages include an early MSA dated broadly to 279,000±47,000 years, a highly retouched form of MSA at 157,000±21,000 years and a minimally retouched, expedient MSA assemblage from a series of occupation horizons at 121,000±6000 years. The latter represents multiple brief visits to a hunting and butchery site on the edge of an active spring pool, where periodic sedimentation gently buried occupation debris in a near-pristine context. Periods of lower spring discharge are represented by organic horizons as swampy vegetation encroached on the springs, while periods of higher spring discharge created pools. Overall the spring sequence indicates low-energy subaqueous environments similar to lakes, ponds or backwater sites. The sequence is characterized by fine sands, silts and clays responsible for the good archaeological preservation.  相似文献

This paper describes a reconnaissance, high-resolution, study of stable isotopes (δ18O and δ13C) from modern shells of the estuarine bivalve Geloina erosa, and those dated to the early Holocene that were harvested by people from mangroves near the Great Cave of Niah on the north coast of Borneo. This reconnaissance study provides high-resolution palaeoclimatic-palaeohydrological information concerning early human activity in the region and the past character of the Southeast Asian Monsoon. Laser ablation continuous flow isotope ratio mass spectrometry (LA-CF-IRMS) on modern shells of Geloina erosa revealed ‘saw-tooth’ stable isotopic profiles that bear a close resemblance to peaks and troughs of trends in recent local rainfall, including the 1998 El Niño drought, highlighting the potential of Geloina erosa for reconstructing seasonality of the Southeast Asian Palaeomonsoon. LA-CF-IRMS analysis of prehistoric shells of Geloina erosa held in the Harrisson Archives of the Sarawak Museum revealed cyclical shifts in δ18O with similar amplitudes of variation as found in modern shells of Geloina erosa. As at the present day, this probably reflects the changing seasonality of the monsoon rains with shifts to negative δ18O values during periods of high runoff. Lighter mean δ18O values of the prehistoric shells, however, may indicate a greater annual surplus of rainfall and possibly consistent with the early Holocene strengthening of the summer monsoon at that time. The similarity of the last growth increment δ18O of the prehistoric shells to their mean δ18O profile values suggests that gathering took place during times of moderate runoff.  相似文献

Establishing and sustaining agricultural production was a key factor in the success of Norse settlements during the landnám colonisation across the North Atlantic. In light of the occurrence of channel features in several abandoned home-field areas of the Norse Eastern Settlement of Greenland, and the irrigation requirements of present-day Greenlandic sheep-farmers questions are raised: was irrigation used by the Norse settlers of Greenland on their home-field areas? and, if so, how frequently? Modelling of soil chemical, physical and soil-water hydraulic properties integrated with contemporary high-resolution climatic data demonstrate a frequent requirement for irrigation. Soil moisture deficits are related to the duration and intensity of winter temperature. Using the winter Dye 3 ice core δ18O record as a climatic proxy, the frequency of moisture deficits, based on comparing mean winter temperatures, indicates that there was a frequent irrigation requirement to maintain home-field productivity, increasing throughout the period of settlement until the 14th Century.  相似文献

Although minor climatic and sea-level changes have been documented for the South Pacific during the late Holocene, our understanding of the consequent impact of these changes on the marine 14C reservoir, and therefore the 14C content of shellfish, is limited. Ultimately, this has implications for documenting the chronology of human movement and adaptation in this region. In this paper we compare marine reservoir (ΔR) data obtained from tightly controlled archaeological proveniences with known-age, pre-AD 1950 shells from the southern Cook Islands, American Samoa, and Marquesas Islands. Results indicate that there has been no significant change in the near-shore marine reservoir in these three locations over the last ca. 750 years. Furthermore, known-age, pre-AD 1950 shell samples provide more precise ΔR values for use in sample calibration than archaeological paired shell/charcoal samples. This is attributed in part to the limitations of assigning provenance and age to material from archaeological sites. On the basis of these results we conclude that the known-age, pre-AD 1950 shell derived ΔR values can be used to calibrate shell 14C results from deposits of late Holocene age.  相似文献

Plant microfossil analysis was carried out on anthropogenic deposits from Yuku rock shelter, possibly occupied from before 14,200 cal. BP to recent times, in the Papua New Guinea Highlands. Elaeocarpus pollen has extremely high percentages throughout. Starch residues of lesser yam (Dioscorea esculenta) and one or more, undifferentiated Dioscorea species were identified, suggesting processing of these taxa since first use of the site. The latter include Dioscorea alata, Dioscorea bulbifera, Dioscorea nummularia and Dioscorea pentaphylla. Pollen and phytoliths of banana (Musa) appear 5200 cal. BP. We cannot differentiate between naturally growing and cultivated yams and bananas. Putative truffle (hypogeous Ascomycotina) spores in the deposits suggest foraging of truffles.  相似文献

Preliminary studies into methods for improving and safeguarding the preservation of waterlogged archaeological wooden artefacts are presented. Mannitol, sorbitol and trehalose have been tested as replacements for polyethylene glycol (PEG) as a treatment prior to freeze-drying of wooden archaeological objects. The highest anti-shrink efficiency achieved in this short experiment was (70 ± 15) % using a 20% weight per volume solution of sorbitol after soaking for one week. The collapse or eutectic temperature of each solution used was determined using a freeze-drying microscope. Importantly, it was noted that the collapse temperature of the solutions was reduced by several degrees after use for treatment of the wood samples for one month. A freeze-drying microscope with a cold light source has been used to observe the real-time freeze-drying behaviour of various treatments inside a thin section of wood, confirming that this novel technique is indeed possible and useful. Lastly, the effects of magnesium phytate as an iron chelator have been studied. It was found that the treatment lowers the collapse temperature of a PEG 600/2000 solution by roughly 3 °C meaning that objects must be freeze-dried at a correspondingly lower temperature. Iron K-edge X-ray absorption near-edge spectroscopy analysis showed that the treatment extracted approximately half of the iron(III) ions present in the timbers.  相似文献

Farmers of southwest Ethiopia are currently transplanting yams (Dioscorea cayenensis) from wild contexts to home gardens. Ethnoarchaeological study of this practice can inform considerations of agricultural origins in prehistoric times by revealing motives and opportunities that shape decisions to adopt wild-growing plants. In one part of the study area, case studies demonstrate that decisions to manipulate yams may arise mainly among individuals of a particular gender or household composition. Comparisons across the study area illustrate the effects of slight variations in environment and human mobility upon adoption of wild-growing yams. The social and environmental factors that favor or impede manipulation of yams are highly specific and nuanced, and operate on both intra- and inter-community levels.  相似文献
