Fossil ostracods from the uppermost 3m of core LG4 from Lake George all have modern living representatives. This part of the core is thought to represent deposition during the last 60,000 years (see Singh et al., 1981b) and the lake hisotry is traced from a knowledge of the ostracod ecology. The following distinct phases, and their respective timing, are postulated for Lake George (the timing of events should be considered with caution as few 14C dates are available): water fresh and lake full for the periods of 10,200 – 12,000 yBP and 19,100 – 20,700 yBP, water fresh, ephemeral at times, for the periods of 3,200–4,000 yBP, 7,000 yBP, 7,500 yBP, 8,500–10,200 yBP, 12,000–13,500 yBP, 20,700–23,500 yBP, 23,800–27,600 yBP and at some stage between 27,000 and 60,000 yBP; ephemeral saline water for a few short episodes between 3,200 and 4,000 yBP and for the periods of 15,600–17,400 yBP and 23,800–27,600 yBP; lake definitely dry between 17,400 and 19,100 yBP. Data obtained from the ostracods correlate reasonably well with those of lake level fluctuations based on the study of ancient shorelines by Coventry (1976) and others based on facies analyses and the record of plant microfossils by Singh et al. (1981b). 相似文献

This article discusses the geopolitical manoeuvres of the comital House of Flanders, especially of Countess Clemence of Burgundy, to consolidate comital influence and power in the border region of western Flanders, specifically in the area of Bourbourg. By analysing and mapping the shifting patterns of interaction between alliances of both secular and ecclesiastical stakeholders in the charters issued for the abbey of Bourbourg, a female house, during the first decades of the twelfth century, it argues that the foundation and patronage of Bourbourg were engineered to create a symbolic and geo-strategic key site where the interests of the counts of Flanders and their local representatives, the abbot of Saint-Bertin, and members of the local elite converged, and alliances balanced each other. Moreover, through an anthropological approach in which the charters are also considered within the supra-institutional context of the reform movement, this study offers new insights into the dynamic role of Countess Clemence as a promoter and benefactor of Bourbourg Abbey, and also as a manager of her personal network of allies. 相似文献

This study was aimed at individuating characteristics related to the pottery’s firing technique of Classical Roman producers, through the low field single-sided NMR relaxometry. The approach is based on a recent method of analysis, the correlation of the longitudinal and transverse NMR relaxation times of a liquid probe (in this case distilled water) filling the porous system of ceramics. The analyzed findings form two homogeneous classes with dating and place of production well established through the producer trademarks. Pottery findings belong to the black-slipped pottery productions of the Latin ancient city of Praeneste between third and second century B.C. and have been attributed to two different ”patriziae” production families: gens Samiaria and gens Trebonia. A further fragment with Greek kylix style, found in the same archaeological area, has also been analyzed, in order to understand if it had been imported from Greece, or made in Praeneste in imitation of the Greek style. 相似文献

The following paper presents the results of the analysis of the avian prey bones found in uneaten remains of crested caracara (Caracara plancus, Aves, Falconiformes) from La Pampa province, Argentina. Anatomical parts representation and taphonomic modifications were evaluated and compared to results of the evaluation of bone remains recovered from crested caracara’s pellets and to previous studies of other diurnal birds of prey. The results suggest a preferential consumption of some body parts of avian prey, as evidenced in the high frequency of wing elements in the uneaten prey remains. This analysis helps to support interpretative data concerning the origins of avian remains in the zooarchaeological and paleontological record, and contributes to the knowledge of a common predator found throughout diverse environments in South America. 相似文献

Two spring-fed swamp deposits in northwestern Tasmania which contain non-marine ostracods are characterized by an alternation of marl, peaty marl and peaty layers: the Pulbeena Swamp deposit (4.80 m thick) was formed over approximately the last 80,000 years, and Mowbray Swamp (2 m thick) over about the last 110,000 years. Fifteen ostracod species have been recovered from 179 samples: three are new, three are in open nomenclature and the others have living representatives. The ostracod data compared with pollen curves for both sites demonstrate, for most levels, a good correlation between the abundance of ostracods and that of Cyperaceae and Potamogeton-Triglochin pollen. This implies that ostracods can be successfully used as indicators of different water regimes for spring-fed swamps. Comparison of the ostracod fauna from the two Tasmanian sites is also made with that of other known Australian and New Zealand swamp deposits. 相似文献
