A major theme of current archaeological research in the Middle Atlantic region of Eastern North America is the recognition of cultural variability across space and through time. The most significant culture change experienced during the entire time frame of regional prehistory occurred ca. 5000 B.P., when there were major changes in regional environments. Before 5000 B.P., adaptations were characterized by small groups of mobile hunters and gatherers. After 5000 B.P., there were continued growth in regional populations and increases in sedentism, intensive use of a limited range of food resources, social group size, and social complexity. 相似文献

It is not until the fourteenth century that written records offer a glimpse into the coastal societies of Northern Sweden. Records include references to a social stratum referred to as the birkarlar, who were tradesmen engaged in trading with the Sámi. The origin of the birkarlar, their prominent status and the meaning of the term, is an enigma that has been much disputed among scholars although there is consensus about the economic and fiscal supremacy of birkarlar vis-á-vis the Sámi. However, the paradox of tradesmen employing force against their most important circle of suppliers and customers remains a puzzle. The birkarla institution is analyzed by means of alternative reading of historical records from the perspective of the indigenous Sámi and coastal farming communities. The postulated animosity between Sámi and the birkarlar is critically examined in light of the social and economic context of interior and coastal communities during the Late Iron Age and Early Medieval period, and in relation to historically known Sámi kinship relationships and marriage traditions. Data are analyzed with regard to demography and social structure, and from a landscape perspective including the logistics and practicalities of inter-cultural contact. Analyses corroborate that birkarlar were deeply rooted in the coastal communities and fully involved in the regular subsistence activities. They were representatives given a commission of trust and contacts between the birkarlar and the Sámi were characterized by mutuality and inter-dependence. 相似文献

The chronology of prehistoric Sami settlement sites has previously been established by conventional radiocarbon dating of bulk charcoal samples associated with hearths from sunken hut floors (stállo-foundations). Here we present results of a comprehensive dating exercise of stállo-foundations in the alpine area of northern Scandinavia using Accelerator Mass Spectrometry (AMS) radiocarbon dating of charcoal. Over a 3 km2 study area, AMS calibrated ages of hearth charcoal from 22 stállo-foundations across 12 sites securely date these features to between cal. AD 640 and AD 1180. Only small variations in age were found between charcoal samples from different areas of a given hearth. Statistical analysis of all the charcoal AMS radiocarbon dates obtained reveals that 12 stállo-foundations across nine sites are contemporaneous and date to the Viking Period (AD 800–AD 1050). The tightly constrained AMS-based chronology of stállo-foundations contrasts with the existing chronology based on conventional radiocarbon analysis, which places these features within a significantly greater time-frame of between AD 600 and AD 1900, with most dates ranging between AD 800 and AD 1350.This discrepancy is likely to result from the necessity of collecting composite hearth charcoal particles, which may originate from different phases of occupation, in order to achieve the required final carbon content for conventional radiocarbon analysis. We argue that the new AMS-based radiocarbon chronology of stállo-foundations presented here supersedes the existing chronology based on conventional (Gas Proportional counting) radiocarbon analysis and we advocate the use of AMS radiocarbon dating in future hearth investigations. 相似文献

Poropat, S.F., Nair, J.P., Syme, C.E., Mannion, P.D., Upchurch, P., Hocknull, S.A., Cook, A.G., Tischler, T.R. &; Holland, T. XX.XXXX. 2017. Reappraisal of Austrosaurus mckillopi Longman, 1933 from the Allaru Mudstone of Queensland, Australia’s first named Cretaceous sauropod dinosaur. Alcheringa 41, 543–580. ISSN 0311-5518Austrosaurus mckillopi was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material of the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the material collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualized through CT data, validates it as a diagnostic titanosauriform taxon, tentatively placed in Somphospondyli, and characterized by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature that appears to be autapomorphic) and by the presence of a robust ventral mid-line ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the ‘Hughenden sauropod’) from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum.Stephen F.

ABSTRACTIn 1101 the Holy Fire failed to appear in the Church of the Holy Sepulchre on Holy Saturday, as tradition and liturgy dictated. Less a failure and more a deliberately precipitated crisis born of a political struggle of wills between Patriarch Daimbert and King Baldwin, the resolution of this event enabled the kings of Jerusalem to establish dominance over the ecclesiastical sphere for most of the kingdom’s history. A reading of the narrative sources against liturgical sources casts light on the intersection between liturgy and government and on how the simulation of miracles could be used to advance political causes. 相似文献
