A cropmark complex of ring-ditches and square-plan ditches in the Vale of Clwyd, North Wales has been partially excavated. Mesolithic activity is represented predominantly by lithic waste in local cherts. A small bronze age cemetery, dated to between about 1660–1400 b.c., comprises a large and small ring-ditch and a ‘flat cemetery’ associated with Beaker inhumation burials, and by cremation burials, of which some were found with Food Vessel Urns. The larger ring-ditch was superseded by an undated rectangular enclosure with causeways at the centre of each side. An early medieval inhumation cemêtery, with associated dates of about a.d. 510 and a.d. 860, was established to one side of the larger ring-ditch. A small proportion of the graves are enclosed by square-plan ditches, two of which had a causeway at the centre of the eastern side. Generalized parallels are drawn with other sites in eastern and northern Britain and within Wales itself.  相似文献

Abstract

The tiled pavement in the nave of Haughmond Abbey, Shropshire, has been partly exposed twice in the last hundred years. Although no decoration appears to survive in situ, a few decorated tiles in the loose collection may derive from this floor. The most significant of these, a roundel fragment, carries the design of a tonsured monk with a crozier. Although this design and the whole mosaic arrangement of the in situ tiles are unique, a comparison can be drawn with the pavement donated by Abbot Nicholas at Halesowen. The arrangement of roundels and frame tiles and the subject matter of the decorated roundels are sufficiently similar to posit a direct connection. There are no close dates for the Haughmond floor, but it is suggested that the Halesowen pavement, dated 1290–98, was the prototype.  相似文献

Conflicts over oysters intensified along the US mid-Atlantic coast as traditional management of these valuable resources broke down in the late nineteenth century. In response, states founded management agencies, and mapping oysters was one of their first activities. Virginia and Maryland's first cartographers favored privatizing common property, an alteration that would have displaced thousands of oystermen and benefited wealthier segments of the industry. Cartographers sought to use maps to expand privatization; however, Chesapeake Bay oystermen were numerous enough to wield political influence, and they rejected one of the first major surveys and shaped the production of the other two, using them to protect their common property while making these rights visible to the State. Many conservation practices in the eastern USA grew out of local people's traditions, and this study explores the role of the mapping process amid the broader context of a shift in the scale of management to state agencies.  相似文献

Turvey, S.T. & Siveter, D.J., June 2007. Assignment of the South Chinese Ordovician trilobite Calymene paronai to Neseuretus. Alcheringa 31, 173‐183. ISSN 0311-5518.

Calymene paronai Pellizzari, 1913 Pellizzari, G. 1913. Fossili Palaeozoici antichi dello Scensi (Cina). Rivista Italiana di Palaeontologia, 19: 3347.  [Google Scholar] was described on the basis of an almost complete enrolled specimen from the Ordovician (probably the early Llanvirn Yangtzeella poloi Biozone) of southern Shaanxi, China. It represents one of the first Chinese trilobite species to have been established, but has been almost completely ignored by subsequent workers. This species is redescribed and reassigned to the Gondwanan inner shelf indicator calymenid Neseuretus, compared with other South Chinese taxa previously assigned to this genus, and interpreted as a senior synonym of N. concavus Lu, 1975 Lu, Yanhao. 1975. Ordovician trilobite faunas of central and southwestern China. Palaeontologica Sinica, New Series B, 11: 1463. (in Chinese and English) [Google Scholar].  相似文献
