BETWEEN 2005 AND 2007, a large Anglo-Saxon cemetery was excavated at Street House, near Loftus in Cleveland in north-eastern England. The site was discovered during a programme of research into late-prehistoric settlement in the area and hosts a range of monuments dating from 3000 bc to ad 650. In the context of the conversion period, the Anglo-Saxon cemetery is of significant interest due to a range of reused prehistoric and Romano-British objects found as gravegoods. By ad 650, when some of the objects were buried, they were already antiques, and some may have been at least 250 years old when deposited. During the conversion period, furnished burial was a diminishing rite and the placement of objects within the grave may therefore have held a greater significance. This study considers reused artefacts recovered from conversion -period cemeteries. At a time when a number of cemeteries were being founded in relation to earlier monuments, some contained burials that reused artefacts and jewellery of prehistoric and Romano-British date. There is a compelling pattern for this practice at Street House, but this phenomenon also occurred at other sites of a similar date.  相似文献

Abstract

In the present article, pollen analytical results from Lake Kirkkolampi are presented and compared with results provided by archaeological material. Pollen analysis is connected with the archaeological research project at Papinniemi in Uukuniemi. Papinniemi is one of the numerous Greek Orthodox settlements that existed in Karelia in the fourteenth to seventeenth centuries. Archaeological evidence of settlement preceding this period is very scarce, and in this respect Uukuniemi represents a typical area in eastern Finland. There is no archaeological evidence of permanent settlement in Uukuniemi from the Early Metal Period (c. 1800 bcad 400), the Middle Iron Age (c. ad 400–800) or from the Late Iron Age (c. ad 800–1300). Pollen analysis demonstrated the onset of cultivation c. cal ad 300. Marked intensification of agricultural activities and cultivation in permanent fields took place around cal ad 800. A shift in land-use practises, including a declining use of fire, is visible at cal ad 1520–1600. The discrepancy between archaeological and palaeoecological records raises several questions, and the problems of Early Metal Period and Iron Age populations, as well as settlement continuity, are discussed.  相似文献

The aim of the present article is to reconsider the interpretation of the Greek word halourgos (?λουργ??) and its relation to textiles and purple dye by reinvestigating its recordings in Greek epigraphy and the papyri, as well as comparative examples from Greek literary sources, in the period from the fourth century bc to the seventh century ad — thus combining the source material from ancient Greece and the Greek-speaking part of the Roman world. This will illustrate the wealth of information one can get from the exploration of one single word: not only on the significance and appearance of textiles and garments in the ancient world from Greece to Egypt, but also on the diversity of colours and the subtleties in their use and terminology.  相似文献

A SOCIAL APPROACH TO MONETISATION shifts the attention from the classic money media — gold and silver — to the dissemination of two social practices: valuing and paying. When these two monetary practices first became widespread in western Scandinavia during the gold rich migration period (in the 5th to 6th centuries ad), they were not introduced in the sphere of trade, but instead were features of traditional or customary payments, such as weregeld (atonements for murder or offences against the person) or marriage dowries. By the Viking Age, in the late 8th to 10th centuries ad, despite flourishing commodity production, precious metals were used as payment in trade solely in towns. Even in towns, this commercial use seems to have been adopted late, and was employed only occasionally. This paper reviews the changing approaches to money and monetisation, and draws attention to the potential for regarding monetisation as the spread of a set of social practices.  相似文献

NEW DISCOVERIES may indicate the location of a previously unknown early medieval burial ground in central Northumberland. Objects discovered during the course of metal-detecting include an assemblage with a folded, pattern-welded sword and zoomorphic shield mount. Excavation indicated near total destruction of deposits as a result of post-medieval land-use and only Bronze-Age burials inserted into bedrock remained intact. Three putative early medieval burials are identified here, with the largest assemblage associated with a high-status male. The sword and shield mount from this assemblage are comparable with finds from high-status burials in southern and eastern England. Together with the landscape context of the site, the assemblage provides evidence for the burial practices of an emerging Northumbrian elite in the late 6th century ad.  相似文献

Abstract

THIS ARTICLE presents a summary and interpretation of burial practices in Scotland in ad 400–650. Due to the dearth of documentary sources, mortuary archaeology provides a window on the changes occurring at the juncture between prehistory and history. Yet previous work has generally approached burial as evidence for a single aspect of this transition: the conversion to Christianity. Rather than signalling ethnic or religious affiliation, it is argued that graves should be understood as acts of structured deposition which enabled new relationships to be forged between the living and the dead at a local level. The composition of the grave with stone, sand, timber and earth can be seen as a form of furnishing cognate with the use of grave goods elsewhere in Britain and the continent.  相似文献

Distinctive accounts of the origin of snakestone beads occur in the folklore of Britain. The beads, usually formed of glass, were believed to be generated by the action of a knot of living snakes. This work considers snakestone bead folklore and explores when it may have developed—evaluating theories ranging from direct descent from the first century ad to early modern reinvention. Accounts of the creation of the snakestone bead from Scotland, Cornwall, and Wales are examined and compared, resulting in the identification of features unique to the folklore of each region.  相似文献

Abstract

The archaeological record in mainland Southeast Asia from ca. 2000 b.c. to the formation of early states in the mid-first millennium a.d. is built on excavations in mounded settlements that incorporate habitation, industrial, and mortuary remains. For most sites, formation processes are not readily identified. have presented a new view of the social organization of the Southeast Asian “metal age” based on a reinterpretation of mortuary and settlement data, founded on their premise that the dead were interred in, under, or in conjunction with domestic residences rather than dedicated cemeteries. They argue that such house societies were instruments for remarkably long-term occupation of individual settlements by heterarchic, non-violent supravillage affiliative social groupings. A detailed examination of the evidence for such residential burial suggests a lack of convincing evidence until the Iron Age. Moreover, new dating programs have shortened the prehistoric sequence, leading to more rapid and intense social changes than hitherto suspected.  相似文献

Late Permian rugose corals are described from a limestone unit of the Gua Musang Formation at Selborne Estate, Padang Tengku area, Pahang, peninsular Malaysia. These include one genus, Iranophyllum, which is reported for the first time from Malaysia, with two new species Iranophyllum aequabilis and I. pahangense belonging to Waagenophyllidae. A Late Permian age is confirmed by a Paleofusulina–Colaniella–Reichelina foraminiferal fauna co-preserved with the corals.

Brea, M., Zamuner, A.B., Matheos, S.D., Iglesias, A. & Zucol, A.F., December, 2008. Fossil wood of the Mimosoideae from the early Paleocene of Patagonia, Argentina. Alcheringa 32, 427–441. ISSN 0311-5518.

An anatomically preserved mature stem from the Salamanca Formation (early Paleocene) at Palacio de Los Loros, central Patagonia, Argentina, is described and assigned to Paracacioxylon frenguellii sp. nov. The material was preserved by siliceous permineralization and shows features of the secondary xylem typical of subfamily Mimosoideae. This species represents the oldest record of the genus and of the Leguminosae along the western border of Gondwana, and is the world's second oldest record of Leguminosae wood. The species is characterized by ring-porous to semi-ring-porous vessels that are solitary, in multiples of 2–4 and clustered, simple perforation plates, alternate and vestured inter-vessel pitting, homocellular 1–6 seriate rays, tyloses, crystals and diffuse apotracheal, vasicentric paratracheal and confluent axial parenchyma. Paracacioxylon frenguellii has anatomical similarities to Acacia Miller. The presence of Paracacioxylon frenguellii associated with pulvinate leaves suggests that the legumes might have been a component of mesothermal forests developed along the western margin of the Golfo San Jorge Basin during the early Paleocene.  相似文献

Wang Yi, Fu Qiang, Xu Honghe, & Hao Shougang, June, 2007. A new Late Silurian plant with complex branching from Xinjiang, China. Alcheringa 31, 111-120. ISSN 0311-5518.

A new fossil plant is described from the middle part of the Wutubulake Formation (late Pridoli) of Xinjiang, China. This plant demonstrates at least two orders of branching. The first-order axis has pseudomonopodial branching with alternately attached second-order axes. Fertile units are alternately inserted along the second-order axis, and consist of a branching system and two sporangia at each tip. Sporangia are narrowly obovate with rounded apex and tapering base. This plant is characterized by more complex branching than other Silurian and Early Devonian plants, and is named Wutubulaka multidichotoma gen. et sp. nov., and placed under open higher-order nomenclature.  相似文献

A new genus and species, Emwadea microcarpa Dettmann, Clifford & Peters, is established for ovulate/seed cones with helically arranged cone scales bearing a centrally positioned, inverted ovule from the basal Winton Formation (late Albian), Eromanga Basin, Queensland. The cones are small, prolate ellipsoidal (9.5–14 mm vertical axis, 6.3–8.7 mm transverse axis) with wedge-shaped cone scales bearing winged seeds attached adaxially to the scale only by tissues surrounding the vasculature entering the ovule. Ovuliferous tissue that is free from the cone scale extends distally from the chalaza; the seeds' lateral wings are derived from the integument. Foliage attached to the cones is spirally arranged, imbricate and with spreading and incurved bifacial blades with acute tips; stomata are arranged in longitudinal files and are confined to the adaxial surface. The cone organization testifies to placement within the Araucariaceae, and is morphologically more similar to Wollemia and Agathis than to Araucaria.

A brachiopod fauna described from the Late Permian of the Gongri and Lizai villages, northwest of the Qoima Co Lake, Tanggula area, southern Qinghai, northwest China, includes ten species in nine genera. This fauna from the (Qiangtang Block) has a strong affinity to coeval faunas of South China, sharing 74% of its species. In addition, the Late Permian Tanggula brachiopod assemblages also demonstrate a clear link with the Middle Permian brachiopod faunas of neighbouring microcontinents including the Indochina block (Malaysia and Cambodia) and the Shan-Thai block (Thailand), as suggested by the presence of Caricula sp. cf. C. salebrosa, Transennatia termierorum and Strophalosiina. This phenomenon indicates that there were relatively narrow seaways between these microcontinents to enable ready interchange of brachiopods during the Permian, and that brachiopods tended to retreat towards the palaeoequatorial region throughout the period.  相似文献

Wang, Z-B., Gao, J-H., Wang, G-H. &; Kang, Z-H., June 2018.2018. Foraminiferal biostratigraphy and facies analysis of the Permian Longge Formation in the Rongma Area, Tibet, China: implications for the palaeogeography of the South Qiangtang Block. Alcheringa XX, x–x.

The Permian Longge Formation in the South Qiangtang Block, Tibet, is overwhelmingly composed of carbonate rocks with various skeletal (brachiopods, foraminifers, gastropods, echinoderms, ostracods, corals, bivalves, algae, and bryozoans) and non-skeletal (intraclasts and ooids) components. Three stratigraphic sections of the Longge Formation in the Rongma area of north-central Tibet—known as South Yibug Caka, Niushan and East Yibug Caka—were selected for this study, which examined both sedimentary facies and foraminiferal assemblages. The foraminifers in these sections consist of at least 38 species belonging to 18 genera. Based on the distribution of the foraminifers throughout the composite section, two foraminiferal assemblages were established, and the age of the Longge Formation was determined to be late Kungurian to Capitanian. During lithological studies, ten microfacies were identified using depositional textures, petrographic analysis and faunal content: mudstone, bioclast wackestone, bioclast perforated-foraminifera packstone, bioclast crinoid grainstone, intraclast wackestone, breccia, intraclast grainstone, ooid grainstone, fine crystalline dolostone and residual-grain dolostone. These microfacies are interpreted to represent four depositional environments—restricted lagoon, open marine, shoal and slope—which together suggest a shoal-rimmed carbonate platform. The non-fusuline foraminifers show transitional palaeobiogeographic affinities (Tethyan Cimmerian subregion), and the assemblage is considered to be influenced by the northward drift of the South Qiangtang Block, the climatic warming after the Late Paleozoic Ice Age and warm-water oceanic currents caused by the newly formed Neotethys Ocean. This indicates that the South Qiangtang Block was located in a relatively warm-water, low-latitude area during the middle Permian. The Permian depositional sequences in the Rongma area were also influenced by the palaeogeographic evolution of the South Qiangtang Block.
