In this study, we report a case of duplication of a lower fourth premolar (P4) on an Iberian wild goat from the archaeological site cave of Arlanpe, (Lemoa, Bizkaia, Northern Spain). The preserved right mandible corpus displays two premolars and the first molar (M1). Both premolars conform in size and general shape to fourth premolars (P4) but the medialmost of the two is rotated 90° counterclockwise, and thus, its wear pattern is different. The comparative analysis to other bovids and the relative scarcity of this anomaly compared to other cases of polydontia and hypodontia suggest that it is a developmental defect consisting in the duplication of the tooth germ, and we doubt on the potential of this abnormality as a territorially based indicator of past wild populations as has been previously proposed.

The results of the ISI 2005 Journal Citation Reports, releasedin June 2006, are once again extremely encouraging for the Journal.As shown in Table 1, on the basis of the citation ‘impactfactor’ rankings, Journal of Economic Geography retainedboth its No. 1 position in geography (out of 38 geography journalscovered by the SSCI) and No. 3 position in economics (out of175 journals covered by the SSCI). The Journal's impact factorincreased marginally to 3.22, indicating that articles publishedin the Journal in 2003 and 2004 were cited on average more thanthree times each in 2005 and, in geography, the gap betweenthe Journal and its major competitors widened slightly. Papersfrom these years achieving significantly higher levels of citationthan the Journal's average in 2005 included Martin and Sunley  相似文献

Driven by progress in sensor technology, algorithms and data processing capabilities, the recording and 3D virtual modelling of complex archaeological sites is currently receiving much attention. Nevertheless, the problem remains the huge effort and costs that have to be invested to obtain realistic models. Besides on-site measurements, much time is often spent in manually rebuilding the whole site with a CAD package or a 3D-modelling tool.  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

Excavations at the archaeological site of Encosta de Sant'Ana (Lisbon, Portugal) uncovered a mid-Holocene buried alluvial soil associated with early Neolithic occupation layers. Routine laboratory analyses and micromorphological observations were undertaken on the soil material. Humic acids from its Ab horizon, as well as Neolithic ecofacts, were radiocarbon dated. The dates obtained indicate that soil was formed between c. 8.0 and 6.0 cal ka BP and that the pedological evidence fits the record of the North Atlantic Holocene IRD events (“Bond events”) and the so-called “Holocene climate optimum”. The geoarchaeological record reveals that Neolithic inhabitants settled upon a stable surface, still affected by soil formation that was suddenly interrupted by slope wasting, probably in correspondence to Bond event 4, at c. 6.0 cal ka BP.  相似文献

ABSTRACT

Focusing on John Toland, Anthony Collins and Matthew Tindal, this article argues that the English deists’ tolerationist ideas played a significant role in their religious thinking, which consisted of their ‘religious thoughts’ and their ‘thoughts about religion’. As regards their ‘religious thoughts’, those deists regarded rationality as the highest state of human existence, because only the proper use of reason could lead humanity to true morality, happiness and (at least in Tindal’s case) eternal salvation. Thus, they considered toleration, entailing freedom of conscience, thought and expression, as a necessary means to enable humankind to pursue ‘true religion’, namely rationality. As to their ‘thoughts about religion’, they appropriated and rethought the foundational sources and tenets of the Judeo-Christian tradition (and, in Toland’s case, of Islam as well) for a twofold purpose: they attempted to debunk the divine right system of power, which opposed toleration and was widely considered to be based on Christian texts and principles; moreover, they aimed at assimilating the original versions of the three major Abrahamic religions, which in their opinion taught morality and toleration, into their own deistic worldviews, which they tried to prove truer and historically more reliable than the positive religions of their time.  相似文献

We promised in our last editorial (Puga and Wrigley, 2004) toreturn with news of the Journal's performance in the ISI citation‘impact factor’ rankings. That is to say, to givereaders the opportunity to gauge how the Journal is beginningto fare in the ‘market place for ideas’. June 2005saw the release of the ISI 2004 Journal Citation Reports (JCR)—thefirst year Journal of Economic Geography appears in the JCR.The result (Table 1) is remarkable. On the basis of citation‘impact factor’, Journal of Economic Geography entersthe rankings as No. 1  相似文献

During the last glacial maximum, the west European modern humans adapted to adverse conditions and their populations subsisted exploiting the natural resources available. Fish were always present as a source of animal protein, although their importance in the human diet and their contribution to the expansion of humans has not been fully explored. Based on the compilation of zooarchaeological evidences from north Spanish sites we have discovered a constant pattern of exploitation of freshwater fish (Salmonids) with high incidence in the human diet during the Upper Paleolithic. Shifts in the exploitation of marine resources can be explained by climate-related geographical changes. The characteristics of salmonids that make them target species for supporting human survival in adverse climate periods are identified and discussed.  相似文献

The analysis of dietary traits of ungulates through tooth microwear and mesowear has been applied to archaeological sites to investigate seasonal changes in settlements by hunter–gatherers. In this paper we propose to test the hypothesis that tooth microwear (combined to mesowear) is able to indicate seasonality in the diet of extant ungulates in arid habitats (semi-deserts or steppe). The material analyzed comes from six faunal monospecific assemblages of guanaco (Lama guanicoe) resulting from a mass mortality event in winter 2000 near the Cardiel Lake in Southern Patagonia (Province of Santa Cruz, Argentina). Mesowear results indicate that the guanacos from the Cardiel Lake area are mixed feeders, and thus, have a diet that shifts seasonally. Moreover, microwear analysis supports the hypothesis that tooth microwear is able to indicate seasonality in the diet of extant guanaco in arid habitats. The pattern is clear for the winter sample and needs to be confirmed for a summer sample. Consequently, tooth microwear is proposed as a new potential proxy for detecting seasonal occupation in archaeological sites in Patagonia and other arid environments.  相似文献
