Malinky, J.M. & Geyer, G., 6 March 2019. Cambrian Hyolitha of Siberian, Baltican and Avalonian aspect in east Laurentian North America: taxonomy and palaeobiogeography. Alcheringa 43, 171–203. ISSN 0311-5518.

Newly identified hyoliths from early Cambrian ‘Small Shelly Fossil’ assemblages in New York State and Quebec extend the geographical ranges of hyolith taxa, otherwise known only from Baltica and Siberia, into eastern Laurentian North America, and in some cases, are accompanied by significant stratigraphical range extensions. The newly recognized taxa from this region include the hyolithids Hexitheca washingtonensis sp. nov., Aimitus sp., A. sp. cf. A. communis, Anabaricornus sp., Similotheca americana, Grantitheca glenisteri, and the orthothecids Decoritheca sp., Contitheca sp., two species of Holmitheca, and two hyolith species that can not be confidently assigned to an order at this time. Early Cambrian limestone clasts within the Lower Ordovician of Quebec have produced the hyolithids Similotheca americana and Nevadotheca princeps. The occurrences of Aimitus, Anabaricornus, and Holmitheca provide a palaeobiogeographical link with hyolith assemblages in Siberia, and Hexitheca to Baltica. Contitheca not only is known from these areas, but also has been found in west Laurentia, Morocco, Korea and Antarctica. A review of previously named species demonstrates that none of their type materials can be confidently referred to genus or species level because of poor preservation.

To establish historical and archaeological contexts for the case studies presented in this volume, this paper presents a review of the literature on the history and archaeology of almshouses. Because both English and Dutch colonial almshouses were based on European precedents, this paper examines historical research and archaeological work conducted in The Netherlands and England, as well as their North American colonies.  相似文献

The emergence of archaeological interest in native copper in the mid-1800s developed in concert with explanations that privileged the Lake Superior area over other potential sources of copper. Most scholars have thus assumed that when copper artifacts first appeared in Northeastern North America, they arrived as finished implements or were locally made from Lake Superior raw materials. Procurement models that point to Lake Superior as the sole source of native copper have been widely accepted in the absence of systematic large-scale testing. This article evaluates the dominant model for native copper procurement and presents trace element data derived from instrumental neutron activation analysis (INAA) to determine whether hunter-gatherers in the Northeast utilized one dominant source of copper or in fact exploited a number of geological deposits. I specifically report on the chemical characterization of copper from 13 discrete geological deposits and 18 archaeological sites dating to the Late Archaic (ca. 5000–3000 B.P.) and Early Woodland (ca. 3000–2000 B.P.) periods to suggest that the dominant model for native copper procurement is oversimplified.  相似文献

In the Pacific Northwest of North America, researchers routinely suggest changes in human use of animals explain hunter-gatherer organizational changes and development of cultural complexity. For example, most models developed to explain developing cultural complexity invoke salmon in some fashion. Yet until recently, fish remains were not carefully studied and more generally, zooarchaeological evidence has not been systematically used to test models of culture change. This study reviews the 10,000-year-old faunal record in the Pacific Northwest to test predictions drawn from models of resource intensification, resource depression and hunter-gatherer organizational strategies. The records from two subareas, the South-Central Northwest Coast (Puget Sound/Gulf of Georgia) and the Northern Columbia Plateau, are examined in detail, representing 63 archaeological sites. While minor changes in animal use are evident, the overall record is characterized by stability rather than change.  相似文献

Strontium, oxygen, and carbon stable isotope analysis may be used in conjunction with archaeofaunal data to identify resource depression by demonstrating that prey were obtained from more distant locations. We use fauna from Five Finger Ridge, a Fremont site in central Utah, to demonstrate that relative abundances of mountain sheep (Ovis canadensis) declined during a period of increased summer precipitation. Strontium ratio values from this period indicate that sheep were acquired from different locations than the preceding period. Specimens from this period also show a moderate increase in carbon ratio values, suggesting that mountain sheep were acquired from higher altitudes. Oxygen isotopes do not vary between temporal periods, possibly the result of the countering effects of higher oxygen isotope values associated with increased summer temperatures and lower oxygen isotope values present at higher elevations. Collectively, these data support that there were localized population declines of mountain sheep that may be related to either climatic changes or hunting pressure.  相似文献

Using computed femur (F) and tibia (T) volumes and cranial capacity (CC), the Pleistocene geomagnetic acromegalosis (PGMA) model of human evolution is tested in eight series of male skeleton sets (n = 123) from aboriginal North America and North Africa, the majority dated to the Holocene. The material was selected from the extensive multiracial osteometric data base previously assembled in the course of adult residual rickets (RR) skeletal plasticity research in archaeological populations of the Northern Hemisphere, controlling for optimal bone eutrophism, that is, for the absence of sunshine and calcium deficits and demographic stress. Six of the eight series are of hunter-gatherers, including a terminal Pleistocene mesolithic sample from the Maghreb. As predicted by PGMA, a clear osteotrophic response is observed between the F, T, and CC of these populations and their geomagnetic dipole field intensity (GMFI) backgrounds, here expressed in microteslas (μT); along with evidence that the GMFI-dependent osteotrophism is stronger near the sagittal plane. Slightly higher bioenvironmental correlations, also compatible with PGMA, are obtained with a composite environmental osteotrophism parameter (CEOT.J), which incorporates the reciprocal of the archaeological site's reconstructed mean July temperature as a synergizer of GMFI. In a final demonstration of the utility of the new computed osteovolumetrics, it is shown that Skhul IV, to judge from its size and proportions, is a hyperrobust pre-neanderthal male skeleton of early Late Pleistocene interglacial age, and belongs to the North African geographical race.  相似文献

中国代表权问题不仅是美苏为首的两大阵营对抗的最重要的冷战问题之一,而且是美国阵营内部歧见纷呈的问题。朝鲜战争爆发后,维护台湾在联合国的中国代表权符合美国的战略利益,但是英国并不紧随美国的指挥棒合拍地起舞。台湾利用美苏阵营的尖锐对抗,以小搏大,竭力争取美国支持直接否决反对台湾在联合国的中国代表权的方案。台美英三方均有各自的立场与考量,有时限的“缓议案”是三方博弈后的产物。随着美苏阵营对抗的渐趋缓和,台湾当局所能做的必定越来越多的是妥协与退让。  相似文献

Pressure and hydrocarbon migration modelling was carried out in the Tune Field area, Viking Graben, offshore Norway. The pressures are considered to be controlled by compartments bounded by mapped faults. Two different interpreted fault maps at the top reservoir level (Brent Group) are used as input to the modelling. First, a low‐resolution fault map is used, with only the large faults interpreted, and next, both large and small faults are included. The simulations show high overpressures generated in the western area, in the deeper part of the Viking Graben, and hydrostatic in the eastern areas. A sharp transition zone results from using the low‐resolution fault map in the simulations. Small N–S striking faults situated in between the wells have to have higher sealing capacity than expected from juxtaposition analysis alone, to be able to match the overpressures measured in well 30/5‐2 and 30/8‐1S in the Tune Field, and well 30/8‐3 east of Tune. The intermediate pressure in the western part is probably related to flow in the deeper parts of the sedimentary column in the compartment, where well 30/8‐3 is situated. The secondary oil migration models show that overpressures have major effects on the migration pathways of hydrocarbons. The level of detail in the fault interpretation is important for simulation results, both for pressure distribution and for hydrocarbon migration.  相似文献

Camilleri, T.A., Warne, M.T., Holloway, D.J. & Weldon, E.A., 10 May 2019. Revision of the ostracod genus Velibeyrichia Henningsmoen, 1954 from the Silurian and Lower Devonian of North America. Alcheringa XXX, X–X. ISSN 0311-5518.

Known occurrences of the ostracod genus Velibeyrichia are restricted to a number of Silurian to Lower Devonian geological strata in North America: the McKenzie Member of the Mifflintown Formation of Maryland and West Virginia; the Tonoloway Limestone of Maryland, West Virginia, Virginia and Pennsylvania; the Bloomsburg Formation of Maryland, Virginia and Pennsylvania; the Manlius Limestone of New York; and the Decker Limestone of New Jersey and New York. The genus includes six species: V. moodeyi (type species), V. mesleri, V. paucigranulosa, V. reticulosaccula, V. tonolowayensis and V. tricornia. The diagnostic combination of characters for this genus are: distinct deflection of the velum where it crosses the crumina in heteromorphs (adult female specimens), dorsal nodes on lobes L1 and L3, sexual dimorphism of the velum, and in tecnomorph specimens, either a shallow sulcus on lobe L3 or a zygal ridge (in adult tecnomorph specimens) extending from lobe L2 to lobe L3. The presence of one or the other of the latter two characters defines two distinct species groups.

Recent research has characterized the procurement of lithic raw materials for flaked stone technology as embedded in food procurement activities, and constrained by logistical factors such as mass, time, and energy. Many have assumed that these variables reflect the need for humans to both move themselves to resources, and carry materials with them. This paper explores the implication of these ideas through the development of particular research project in the Maritime Peninsula, in the Northeast of North America. Through this research process, I explore the complex interplay among raw materials, bulk procurement, water transportation, and regional patterning of archaeological lithic assemblages. I initially consider the role of embedded procurement as a structuring mechanism for the relationship between lithic raw-material diversity and catchment, but through a exploration of intersite and inter-feature variability, I consider the role of bulk procurement in this patterning. I conclude that canoes may significantly influence hunter–gatherer lithic procurement, in terms of the extraction of resources, and their reduction and use.  相似文献

Zougong, the most important local deity at Sibao, Tingzhou Prefecture, was worshipped by local villagers at least from the Yuan and the Ming dynasties on. The Zou lineages in the area regarded Zougong as their common ancestor. Existing literature usually identifies Zougong as Zou Yinglong, a zhuangyuan in the Southern Song Dynasty. However, such identification appeared only in the late Ming period when local elites of several Zou lineages consciously tried to unite and consolidate their lineages. Before that, Zougong was a mighty ritual master in a series of magic contest stories popular at Tingzhou, rather than a zhuangyuan. The change of his identity from ritual master to zhuangyuan was a result of convergence of Taoist tradition, gentry culture and local culture, which may be called “cultural hybridization,” rather than a simple process by which local culture gave way to gentry culture.

Models derived from foraging theory suggest that high-value prey will be depressed (encounter rates will decrease) relative to low-value prey as human predation intensifies. Numerous case studies in ethnographic and zooarchaeological settings indicate depression of prey is very common. Exceptions to depression are few and have been cited as evidence of conservation and resource management. Reanalysis of pinniped and ungulate data from sites on the Oregon coast indicates that the metapopulation (entire population in the region) of otariids was depressed but a single local population of Steller sea lions exploited over a span of 600 years reached an equilibrium with human predation and was not subsequently depressed. This local population was not historically documented, and thus must have been extirpated by commercial sealing in the late nineteenth century. This singular case of prehistoric epiphenomenal conservation was an unintentional result of human predation that took advantage of the lack of escape behaviors among breeding male Steller sea lions.  相似文献

该文是对美国学者狄宇宙所著《古代中国与其强邻:东亚历史上游牧力量的兴起》进行的延展性评论。作者认为狄宇宙此作从游牧一般性的起源关注中国北方游牧势力的兴起,由此引生出南北互动关系的讨论,是从中原以外的视角作出的有益尝试,呈现给中国学术界以新的意义,特别是其揭示游牧社会与农业社会互动所凸显的方法论意义,更值得中国学者在阅览的基础上去体验与分享。该文又对书中有关长城的描写并结合长城的地理分区谈了自己的想法,认为其逻辑关系应当是:生态环境决定文化和生活方式,文化和生活方式则决定族属划分,国家政治体由民族群体所建构,长城是(王朝、国家等)政治体军事攻防的产物,与民族(族群)、生活方式、自然环境并不产生直接关联。  相似文献

Previous studies of the areal variation in heat flow in the National Petroleum Reserve Alaska (NPRA) support the existence of an active topographically driven regional fluid flow regime in this central part of the North Slope foreland basin. Drilling records and wireline logs for over 30 wells drilled in the NPRA provide additional field information, which can be used to further constrain interpretation of the pattern of regional flow of basinal waters within the NPRA. Hydraulic heads estimated from drilling mud weights show that ground water flow occurs generally from south to north, but with divergence to the north‐east and north‐west away from the central part of the NPRA towards coastal areas of elevated shallow heat flow. Salinities calculated from SP logs range from less than 1 g L?1, to marine values of 35 g L?1, to hypersaline values of over 150 g L?1. The entire upper sedimentary section to a depth of 2 km or more in the eastern part of the NPRA has been preferentially flushed with meteoric water through an area corresponding to the sandiest portion of the Nanushuk group. Deeper areas of low salinity occur within the Sadlerochit and Lisburne sections. The pattern of regional flow in the east is complicated, however, by the presence of a large mass of hypersaline water at depth. It is not known whether these brines are being displaced laterally and upward towards the discharge end of the basin or whether fresher waters are simply riding up over the top. Deep, hypersaline waters also occur in fault slices in the Brooks Range and have survived meteoric flushing. The brines were probably formed at the time of deposition of the Lisburne carbonates. The fluid flow regime to the west is different. Low‐salinity waters may be flowing northward underneath this section through the Ellesmerian section and discharging upward nearer the coast. However, sparse well log control severely limits what can be deduced about the details of flow paths in the central and western parts of the NPRA.  相似文献

The growth increments of otoliths and vertebrae of plaice (Pleuronectes platessa) derived from a 15th century single depositional event at Raversijde (Belgium) are analysed with the aim of reconstructing (a) the age distribution of the population, (b) the season of capture, and (c) the growth rate. Otoliths and vertebrae give slightly different age distributions but it is possible to arrive at similar seasonality estimations in both structures when information from the literature and our own data from monthly captures of plaice from the North Sea are taken into account. These modern data show that the timing of annulus formation in otoliths and vertebrae is more or less similar. Back‐calculations on vertebrae and otoliths yield similar growth curves. The age distribution, the edge condition of both vertebrae and otoliths, and the growth rate obtained on the material from Raversijde all show that the plaice from the studied assemblage were captured during spring in the southern part of the North Sea. Vertebrae are commonly preserved in archaeological sites whereas otoliths rarely survive. Although they are more difficult to read than otoliths, vertebrae of plaice can be used for growth increment analyses, and the growth rates obtained from vertebrae from archaeological sites can, therefore, be compared in the future to growth data from modern otoliths studied in sea fisheries research. Archaeozoological material predating industrialized fishing since the 19th century can hence serve as a reference in the study of the compensatory response of commercially important species to heavy exploitation.

ABSTRACT The ‘Sun and the Shakers, Again’ resumes the conversation begun by Mervyn J. Meggitt in his 1973 article ‘The Sun and the Shakers’ concerning the circumstances and mindset of Enga and Ipili speakers on the eve (or in the early stages) of colonial penetration. The ‘Cult of Ain,’ as Meggitt termed a regional cult that broke out in the mid‐1940s, followed on the heels of devastating epidemics and famine and was in some measure, at least in most areas where it caught on, a response to those traumas. Yet there were other dimensions: apparent cargo cultism and millenarianism. Widening the geographical scope of reporting beyond that of Meggitt's article to include both the Somaip, as reported on by Hans Reithofer in The Python Spirit and the Cross, and the Ipili speakers of the western Porgera valley and the Paiela valley, this second and final installment reviews and critiques existing interpretations of the Cult of Ain in light of the ethnohistorical detail offered in the first installment and goes on to offer an interpretation of the cult that is inspired by the cosmological symbols common to all cult versions: most obviously the sun but also the sky. The Cult of Ain is viewed by participants and their descendants alike as the prelude to colonialism and missionization, and understanding it is crucial to writing the cultural history of the last 65+ years.  相似文献
