Abstract

Two new, subcomplete forewings belonging to the ‘triassolestid assemblage’, a group of Triassic stem-relatives of dragon- and damselflies (Odonata), are described. One, recovered from Australia (Aranbanga Volcanic Group), belongs to Mesophlebia antinodalis Tillyard, 1916, previously documented on the basis of two very incomplete wings. The other, recovered from South Africa (Molteno Formation), is assigned to a new species, Mesophlebia elegans sp. nov. The new data allow a reconsideration of the diagnosis of the genus Mesophlebia Tillyard, 1916 and a re-instatement of the family Mesophlebiidae Tillyard, 1916. Notably, the new specimens possess, near the wing base, a posterior lobe absent in most ‘triassolestid’ genera, but present in crown-Odonata and a number of their stem-relatives. Lobodonata tax. nov. is erected to accommodate odonates possessing this lobe. The nature of the ‘vein-like’ element anteriorly delimiting this lobe is discussed. We submit that it might have been initially composed of an invagination of the posterior wing-margin (‘fibula’), which was later captured by AA, imposing its course on CuP.

Haig, D.W., October 2017. Permian (Kungurian) Foraminifera from Western Australia described by Walter Parr in 1942: reassessment and additions. Alcheringa 42, 37–66. ISSN 0311-5518.

Exceptionally well-preserved siliceous agglutinated Foraminifera originally recorded by Walter Parr in 1942 are redescribed and illustrated by rendered multifocal reflected-light images. Significant new observations are made on wall texture and apertural morphology. The specimens are from the Quinnanie Shale and lower Wandagee Formation in the Merlinleigh Sub-basin of the Southern Carnarvon Basin, a marginal rift that splayed from the East Gondwana interior rift. During the Early Permian, a restricted shallow sea inundated the rift. The formations are part of sequence III of the Byro Group and belong within the Kungurian Stage (Cisuralian, Lower Permian). Of the 14 agglutinated species described by Parr, six are retained under their original names, viz., Hyperammina coleyi Parr, 1942 Parr, W.J., 1942.

The trematosauroid temnospondyl Tirraturhinus smisseni gen. et sp. nov. from the Arcadia Formation of central Queensland, Australia, is described on the basis of its rostrum. This is the first trematosaurine (short-snouted) trematosauroid from Australia, and is considered to be most closely related to Tertrema acuta from Spitzbergen. Tirraturhinus smisseni occurs alongside lonchorhynchine (long-snouted) trematosauroids in the Arcadia Formation; the co-occurrence of both trematosauroid morphotypes in that fauna is repeated in a number of non-marine Early Triassic faunas elsewhere in Pangaea. The Arcadia Formation is probably Griesbachian (earliest Triassic), so that T. smisseni is the oldest known trematosaurine.  相似文献

The basis on which peoples should understand and relate to each other is a key dilemma for applied anthropology and a human rights organization such as the Forest Peoples Programme. Cultural relativism rejects universalism, critiques the individualist emphasis of human rights as Western imperialism and teaches that every society must be understood in its own terms. While it is true that some countries have resisted the impositions of the human rights regime, most have also ratified the key human rights treaties. It is clear that the notion of ‘human rights’ is a cultural construct of Western civilization, with a long gestation dating back to the ancient Greeks. Human rights have three foundational principles: individual rights, non-discrimination and self-determination. The tension between the three creates space for cultural specificity, decolonization and the assertion of collective rights. Indigenous peoples have effectively used the human rights system of the United Nations to reclaim their collective rights and, in so doing, accept that these universal norms also apply to their own societies, which they reform through their self-determined efforts. Ultimately, all human rights trace back to various conceptions of freedom – free will, freedom of belief, autonomy and self-determination – and even in societies where personhood is more relational and communal, notions of collective freedom are readily discernible. We need an ‘anthropology of freedom’ that builds on the insights of cultural relativism but is open to supporting self-determined movements for reform.  相似文献

Peng, J., Li, J., Slater, S.M., Li, W., Zhu, H. & Vajda, V. October 2017. Triassic palynostratigraphy and palynofloral provinces: evidence from southern Xizang (Tibet), China. Alcheringa 42, 67–86. ISSN 0311-5518.

Palynological analysis was carried out on Middle to Upper Triassic strata from Tulong, Nyalam County, southern Xizang (Tibet), China. Well-preserved miospore (pollen and spore) assemblages and sparse acritarch occurrences were identified. We recognized four formal and one informal biozones based on stratigraphically important taxa and compositional changes through the succession, in ascending order: the Triplexisporites Interval Zone (Anisian), the Staurosaccites quadrifidus Taxon-range Zone (upper Anisian to lower Norian), the Striatella Interval Zone (lower Norian), the Craterisporites rotundus Taxon-range Zone (middle to upper Norian) and the informal ‘Dictyophyllidites harrisii zone’ (Rhaetian). The zonation was supported by marine fossils (e.g., ammonoids and conodonts), and compositional similarity between the zones was examined using non-metric multidimensional scaling (NMDS). Correlation with other representative palynological sequences across Gondwana was also conducted. The presence of miospore taxa not previously recovered from the Late Triassic North and South China palynofloral provinces (e.g., Ashmoripollis reducta, Craterisporites rotundus, Enzonalasporites vigens, Minutosaccus crenulatus, Samaropollenites speciosus and Staurosaccites quadrifidus) calls for a new province in southwestern China, i.e., the Southern Xizang Province. It is proposed here that the modern expression of the northern boundary runs along the Yarlung Zangbo Suture, the remnant of the Tethys that separated the Indian Plate (southern Xizang) and the Lhasa Block during the Late Triassic. This new palynofloral province comprises typical elements of the Onslow Microflora, indicating the need for an extension of this microflora in southern Xizang, China.

The presence of cobbles with activity-related marks in the Mesolithic site of Font del Ros (Berga, Spain), and in particular one group of artefacts – pitted stones – raises problematic issues associated with the characterization of percussion activities. Although these artefacts have generated an extensive bibliography on ethological, ethnographic, ethnoarchaeological and archaeological levels, various questions persist in relation to their possible contextual function. In this paper we present the results of an experimental programme in which three types of activities that could create pitted stones are reproduced: bipolar knapping of vein quartz, hazelnut cracking, and hazelnut grinding. The aim of this experimental programme is to describe marks and use-wear traces related to such activities.  相似文献

A non-destructive method – magnetic susceptibility (MS, κ) measurement – was used to characterize about 360 Neolithic, Copper and Bronze age polished stone tools of the Miháldy collection (Laczkó Dezső Museum, Veszprém, Hungary), composed of artefacts from three Neolithic (Moravian Painted Ware) workshops around a source of greenschist at Želešice near Brno (Moravia, Czech Republic) and semifinished artefacts from workshops at Neolithic mines in the Jizerské hory Mts. (Bohemia, Czech Republic); in addition, rock reference samples collected from the possible provenance areas and rock outcrops in the Czech Republic, Slovakia and Hungary were analysed as comparative material with the same method. We elaborated a model experience to control the thickness correction factor (TCF) following Williams-Thorpe et al. (2000).Among various stone raw materials of polished artefacts we found basaltic rocks and greenschists-metabasites as the most common.  相似文献

Anatomical features related to water deficiency were analyzed in archaeological plant charcoal as a paleoenvironmental indicator. The end of the Aguada settlements in the Valley of Ambato (Catamarca, Argentina), which took place towards the end of the first millennium of this era, was used as the case study. Tools from Ecological Anatomy were applied to recreate paleoenvironmental scenery for the studied processes. The results of the analyses showed that this area must have been undergoing a period of arid conditions during the studied period.  相似文献

This paper will discuss Early English Books Online (EEBO) as a tool for locating and researching contemporary references and responses to historical texts and authors, specifically George Sandys' A Relation of a Iourney begun An: Dom: 1610 (1615). It will focus upon two main themes. The first is methodological and will discuss the nature of EEBO and the possibilities and limitations it presents for this kind of historical research. The second turns to a case study of seventeenth-century responses to, and readings of, the Relation and shows how references found through EEBO can both broaden the context within which we view this work and alter our interpretation and understanding of it.  相似文献

We report here on a study of 57 fragments of wall painting excavated from the Temple of Venus (Pompeii). These samples were characterised by a wide range of analytical methods. Data showed that the palette is varied, although not so broad as that found in other buildings in Pompeii, and is consistent with pigments used elsewhere in Pompeii and in the Roman Empire. It is composed of: natural earths, minerals and rare artificial pigments. Paintings are made up of thin paint layers (0.01–0.10 mm thick) strongly adhering to the underlying preparation layer. Nonetheless, in some cases thicker layers (up to 0.40 mm) were recognised, often spread on other previous painting layers. Samples were also compared with the microstratigraphic criteria developed in Piovesan (2009) to distinguish wall painting techniques. This comparison demonstrated that both fresco and lime painting techniques were adopted.  相似文献

The burial and pore fluid pressure history of fluorite ore deposits is reconstructed: (i) at Hammam Zriba–Djebel Guebli along the eastern margin of the Tunisian Atlas; and (ii) at Koh‐i‐Maran within the northern part of the Kirthar Range in Pakistan. Both the deposits are hosted by Late Jurassic carbonate reservoirs, unconformably overlain by Late Cretaceous seals. Microthermometric analyses on aqueous and petroleum fluid inclusions with pressure–volume–temperature–composition (PVTX) modeling of hydrocarbon fluid isochores are integrated with kinematics and thermal 2D basin modeling in order to determine the age of mineralization. The results suggest a Cenozoic age for the fluorite mineralization and a dual fluid migration model for both ore deposits. The PVTX modeling indicates that the initial stage of fluorite cementation at Hammam Zriba occurred under fluid pressures of 115 ± 5 bars and at a temperature close to 130°C. At Koh‐i‐Maran, the F3 geodic fluorite mineralization developed under hydrostatic pressures of 200 ± 10 bars, and at temperatures of 125–130°C. The late increase in temperature recorded in the F3 fluorites can be accounted for by rapid rise of hotter fluids (up to 190°C) along open fractures, resulting from hydraulic fracturing of overpressured sedimentary layers.  相似文献

Twenty-four obsidian artefacts of the Neolithic Age were found at the large karstic doline of Molfetta (near Bari) along the Southern Italian Adriatic coast. Non-destructive chemical analyses of the glass, by SEM-EDS, allowed their source rock regions to be determined. Twenty-three of the studied artefacts had been traded from the island of Lipari. Only one sample had a glass composition and microphenocrysts (biotite, pyroxene and feldspar) that indicate provenance from the Monte Arci area of Sardinia, in particular from the Perdas Urias (SC) outcrops. The attribution of this artefact to Sardinia enlarges the geographical pattern of Monte Arci obsidian exploitation and distribution from island to Southern Italy during the Middle to Late Neolithic.  相似文献

Abstract

A study of plant remains from seven archaeological wells at Mas de Vignoles IX, near Nîmes, southern France, was used to shed light on a current gap in the archaeological record caused by erosion and modern agriculture. The analysis also explored the reliability of these sources for palaeoenvironmental and palaeoeconomical information. Significant results on the spatial organization of human habitation, economic activities, and on the environment and its exploitation were obtained for the Middle Neolithic to Roman periods. Furthermore, the Neolithic wells also provided the first early finds of fig seeds in France. The abundance of weed and ruderal plants up to the Iron Age is consistent with data from other studies and their dramatic decrease during the Roman period may have resulted from radical changes in land management. The study marks the first time, in southern France, that a group of wells from a single site have provided a complete record throughout the later prehistoric and Roman periods.  相似文献

A re-evaluation of the published reports on the Khufu I vessel suggests: first, Egyptian boatwrights used as much of a plank's original width and length as possible to minimize waste, resulting in unpredictable stealer and scarf placement; second, crafting tenons to be narrower than corresponding mortises may have been one of many standardized techniques of Egyptian boatbuilding; third, temporary and permanent edge-to-edge transverse lashing was an important structural feature. Finally, woven straps instead of ropes were probably used to lash this vessel, and seams were probably sealed with wadding and battens, while the frames appear to have been recycled.

This paper presents the results of a series of experiments for the identification and analysis of fire modified rock (FMR). FMR is a common but frequently overlooked artifact type. Experiments were conducted simulating the effects of different hypothetical burning scenarios on rocks similar to those found in a South African Middle Stone Age site. A digital imaging method was then used to quantify FMR color values, designed to limit intra-analyst bias. Statistical tests and a blind test suggest that unburned rocks and experimental FMR can be separated statistically based on physical appearance. Two burning scenario models, based on measured experimental data were applied to archaeological FMR from a South African Middle Stone Age site named Pinnacle Point 5-6 (PP5-6) and show that the archaeological samples are not statistically different from a simulated campfire and possibly a lithic raw material heat-treatment fire.  相似文献
