An example of ante‐mortem cranial perforations in the skull of a European wisent (Bison bonasus) from Armenia is presented. The implications for reinterpreting the possible causes of this condition in ancient domestic cattle (outlined in a previous paper) are briefly discussed.

We have undertaken a preliminary survey of the occurrence of cranial perforations which have been noted on the posterior portion of archaeological cattle skulls. The interest arose from the authors independent encounter with unusually high frequencies of this condition in assemblages from Bruges and Lincoln and the subsequent search for an explanation. A rapid literature survey and direct contact with other colleagues in the field showed that the phenomenon is widespread in European material and represented throughout a range of time periods and geographical locations. It is also clear that a variety of diverse but untested theories have been proposed by various workers in an attempt to explain the condition. A number of possible aetiological factors are discussed in an attempt to establish the most likely explanations. On the basis of this brief survey, which includes the evaluation of additional archaeological evidence from some of the assemblages, it would appear that parasites, tumours and infection can be ruled out as causal factors. Although not clearly established, it is suggested that a congenital or yoking pressure origin is more likely. If this is the case, then the presence of cranial perforations in domestic cattle may provide important information regarding the temporal and spatial spread of a specific congenital condition or yoking practice. Only a wider survey of both archaeological and modern comparative material (including other bovid species) will enable a full appraisal of the yoking versus congenital hypothesis.  相似文献

The analysis of phytoliths, pollen, charcoal and other macroremains was carried out in the neolithic shelter of “La Grande Rivoire”, Vercors massif (French Alps). The results show the predominance of tree species, in the form of phytoliths, clustered pollen, stomata, small branches charcoal, needles, bark, buds… The practice of leaf fodder is already known in the alpine and circum-alpine area from archaeological and historical sources. The analyses of the neolithic dung levels of “La Grande Rivoire” illustrate the use of leafy and flowering tree branches as fodder. The results also suggest that some species were used for special purpose in relation with the tending of livestock (litter, dietary supplement, veterinary practices).  相似文献

A new case is described here of a wound caused by a flint arrowhead in the neolithic period. The specimen comes from a collective burial excavated last century in the cave Trou Rosette (Belgium). It consists of a fragment of left adult ilium. The fragment of arrowhead is located in a rounded cavity which is open in the medial surface of the bone. The CT scan and the artefact study allow us to reconstruct the scenario of the accident. The arrow pierced the musculus gluteus of the individual prior fixing in the iliac blade. The arrow tip broke at the moment of impact; its tang broke either at the moment of impact or during attempts to extract the arrow.  相似文献

Large quantities of sardine (Sardina pilchardus) bones from amphorae in a wreck at Randello, Sicily, were examined. Methods of estimation of size of the fish represented using the lower jaw bone (dentary) and the gill cover (operculum) by comparison with those of modern fish are given. Both methods give comparable results; from dentaries 108–171 mm and from opercular bones 116–176 mm total length.  相似文献

Human skeletal remains of sixteen individuals found at Dibba al‐Hisn in the Emirate of Sharjah (UAE) are analysed with regard to standard anthropological criteria. They represent the poorly known pre‐Islamic period of the first centuries AD. Remains of at least fifteen individuals were recovered from a semi‐subterranean grave‐chamber together with rich archaeological grave‐goods. An additional, almost complete skeleton was found in the open area near the chamber. While the size and nature of the sample prevent demographic analyses, skeletal features studied with the help of macro‐ and microscopic as well as radiographic methods provide details on individual life histories and living conditions, as well as mortuary habits and taphonomic processes. Of special interest is a case of intentional tooth mutilation as well as two cases of skull trauma apparently caused by violent inter‐personal conflict. The results of the analysis of the faunal remains from the grave‐chamber and its surroundings are presented in an appendix .  相似文献

A marine electric resistivity survey was carried out over a submerged beach along the Agropoli shore (Salerno, Italy) to detect buried objects of archaeological interest below the sandy seabed. We found a shipwreck, a military vessel that probably sunk during the Salerno landing operations of the allied forces in the Second World War. Resistivity data provide information on the vertical and horizontal extension of the shipwreck, which is characterized by very low calculated resistivity values (about 2–5 ohm m). Such values differ significantly from the sand and the bedrock values (5–40 ohm m). Although the presence of the shipwreck is clearly visible from geoelectric data, the joint application of electric, magnetic and multibeam bathymetric techniques reduces the ambiguities inherent in each method. As shown in the Electrical Resistivity Tomography (ERT) and confirmed by the Digital Elevation Model (obtained from the processing of bathymetric data), the shipwreck extends more than 30 m in NE–SW direction and it is about 13 m wide. The global extension of the relic is consistent with the magnetic data, that are characterized by a magnetic anomaly with an amplitude of about 1800 nT and similar dimension, as inferred from the estimation of source boundaries obtained from the computation of the analytic signal. The results of our survey encourage the use of marine geoelectrical methods for the detection of buried archaeological targets, particularly in locations where the use of seismic prospecting is not effective (e.g. very shallow water with sandy sea-bottoms). The integration of different geophysical methods allows to better define the extension, depth and thickness of buried objects, suggesting that such an approach is the most effective for underwater archaeological investigations.  相似文献

Chamberlain, P.M., Travouillon, K.J., Archer, M. & Hand, S.J., November 2015. Kutjamarcoot brevirostrum gen. et sp. nov., a new short-snouted, early Miocene bandicoot (Marsupialia: Peramelemorphia) from the Kutjamarpu Local Fauna (Wipajiri Formation) in South Australia. Alcheringa 40, XX–XX. ISSN 0311-5518.

A new bandicoot species, Kutjamarcoot brevirostrum gen. et sp. nov. (Peramelemorphia), is described here from the Leaf Locality, Kutjamarpu Local Fauna (LF), Wipajiri Formation (South Australia). The age of the fossil deposit is interpreted as early Miocene on the basis of biocorrelation between multiple species in the Kutjamarpu LF and local faunas from the Riversleigh World Heritage Area (WHA). Kutjamarcoot brevirostrum is represented by isolated teeth and three partial dentaries and appears to have been short-snouted with an estimated mass of 920 g. Phylogenetic analyses place K. brevirostrum in a clade with extant Australian bandicoots and the extinct Madju, but potentially exclude the extant New Guinean bandicoots. Morphometric analysis infers close similarity between K. brevirostrum and species of Galadi in both size and rostral length. They, thus, potentially occupied compatible ecological niches with competitive exclusion perhaps explaining geographical segregation between these broadly coeval lineages.

The calc‐alkaline plutonic complex from Charroux‐Civray (north‐western part of the French Massif Central) displays multiphase hydrothermal alteration. Plutonic rocks, as well as early retrograde Ca–Al silicate assemblages, which have crystallized during cooling and uplifting of the plutonic series, are affected by multiphase chlorite–phengite–illite–carbonate alteration linked to intense pervasive fluid circulation through microfractures. The petrographic study of alteration sequences and their associated fluid inclusions in microfissures of the plutonic rocks, as well as in mineral fillings of the veins, yields a reconstruction of the PTX evolution of the Hercynian basement after the crystallization of the main calc‐alkaline plutonic bodies. This reconstruction covers the uplift of the basement to its exposure and the subsequent burial by Mesozoic sediments. Cooling of the calc‐alkaline plutonic series started at solidus temperatures (~650°C), at a pressure of about 4 kbar (1 bar = 105 N m?2), as indicated by magmatic epidote stability, hornblende barometry and fluid inclusion data. Cooling continued under slightly decreasing pressure during uplift down to 2–3 kbar at 200–280°C (prehnite–pumpellyite paragenesis). Then, a hot geothermal circulation of CO2‐bearing fluids was induced within the calc‐alkaline rocks leading to the formation of greisen‐like mineralizations. During this stage, temperatures around 400–450°C were still high for the inferred depths (~2 kbar). They imply abnormal heat flows and thermal gradients of 60–80°C km?1. The hypothesis of the existence of one large or a succession of smaller peraluminous plutons at depth, supported by geophysical data, suggests that localized heat flows were linked to concealed leucogranite intrusions. As uplift continued, greisen mineralization was subsequently affected by the chlorite–phengite–dolomite assemblage, correlated with aqueous and nitrogen‐bearing fluid circulations in the temperature range of 400–450°C. In a later stage, a continuous temperature decrease at constant pressure (~0.5 kbar) led to the alteration of the dolomite–illite–chlorite type in the 130–250°C temperature range.  相似文献

A field survey revealed that Byzantine and Early Arab (ca. 5th to 8th century C.E.) agricultural systems in the semi-arid region of the Shephelah (central Israel) were similar to runoff agricultural systems in the arid region of the Negev (southern Israel). This similarity led to the hypothesis that systems in the Shephelah also function as runoff farms. This hypothesis is not trivial since runoff values in semi-arid regions are generally low due to intensive but short rainfall events, and due to the presence of sink patches that absorb runoff on slope surface. The aim of the current research is to examine whether runoff potential in a representative agricultural system in the Shephelah is sufficient for sustaining runoff farming. A geoarchaeological field survey and digital terrain analysis show that large Nari (calcrete) outcrops on the footslopes generate high runoff values that improve water potential. Hydrological simulations and calculations show that 230 mm of direct rainfall generates a water potential equivalent to 300 mm of direct rainfall. In view of these results, it is reasonable to conclude that the presence of Nari enabled runoff agricultural farming in the Shephelah region, even in drought years.  相似文献

The highest platforms of As Laias, a settlement located in northwest Iberia, were used for storage during the Iron Age and until the turn of the Era. In this time-span, the whole hilltop – the croa – was a walled enclosure mostly used for storage and due to recurrent fires affecting the settlement's terraces, abundant plant remains were preserved in overlying wattle and daub storage structures.  相似文献

In this paper we evaluate the relative analytical capabilities of SEM-EDS, PIXE and EDXRF for characterizing archaeologically significant Anatolian obsidians on the basis of their elemental compositions. The study involves 54 geological samples from various sources, together with an archaeological case study involving 100 artifacts from Neolithic Çatalhöyük (central Anatolia). With each technique the artifacts formed two compositional groups that correlated with the East Göllü Da? and Nenezi Da? sources. The non-destructive capabilities of these methods are emphasized (albeit with certain analytical limitations in the case of SEM-EDS), suggesting important new techniques for Near Eastern obsidian provenance studies.  相似文献

Quartz veins in the early Variscan Monts d’Arrée slate belt (Central Armorican Terrane, Western France), have been used to determine fluid‐flow characteristics. A combination of a detailed structural analysis, fluid inclusion microthermometry and stable isotope analyses provides insights in the scale of fluid flow and the water–rock interactions. This research suggests that fluids were expelled during progressive deformation and underwent an evolution in fluid chemistry because of changing redox conditions. Seven quartz‐vein generations were identified in the metasedimentary multilayer sequence of the Upper Silurian to Lower Devonian Plougastel Formation, and placed within the time frame of the deformation history. Fluid inclusion data of primary inclusions in syn‐ to post‐tectonic vein generations indicate a gradual increase in methane content of the aqueous–gaseous H2O–CO2–NaCl–CH4–N2 fluid during similar P–T conditions (350–400°C and 2–3.5 kbar). The heterogeneous centimetre‐ to metre‐scale multilayer sequence of quartzites and phyllites has a range of oxygen‐isotope values (8.0–14.1‰ Vienna Standard Mean Ocean Water), which is comparable with the range in the crosscutting quartz veins (10.5–14.7‰ V‐SMOW). Significant differences between oxygen‐isotope values of veins and adjacent host rock (Δ = ?2.8‰ to +4.9‰ V‐SMOW) suggest an absence of host‐rock buffering on a centimetre scale, but based on the similar range of isotope values in the Plougastel Formation, an intraformational buffering and an intermediate‐scale fluid‐flow system could be inferred. The abundance of veins, their well‐distributed and isolated occurrence, and their direct relationship with the progressive deformation suggests that the intermediate‐scale fluid‐flow system primarily occurred in a dynamically generated network of temporarily open fractures.  相似文献
