Of the parasite eggs discovered in ancient samples from Korean archaeological sites, Paragonimus spp. are of particular importance in that they are regarded as one of the most insidious trematode infection sources. Although their infection prevalence decreased rapidly in the early 20th century, archaeoparasitological studies on the species are still required, as historical knowledge of paragonimiasis remains far from comprehensive. Fortunately, we recently were given a chance to examine a medieval Korean mummy in a good state of preservation. Using morphological techniques, we discovered evidence of ectopic paragonimiasis in the sample from the 17th-century female. When the ITS 2 gene was extracted, amplified and sequenced from Paragonimus eggs, it showed 100% homology to the sequences of modern Paragonimus westermani reported from Korea and Japan, forming a cluster distinct from South Asian P. westermani. Our report is the first-ever analysis of ancient Paragonimus DNA from any archaeological field in the world. The ectopic paragonimiasis diagnosis made in this study, especially involving the liver sample, also is the first of its kind in archaeoparasitology.  相似文献

Recent studies have highlighted the long-distance transport of obsidian from the Paektusan (Tianchi or Baitoushan in Chinese) volcano on the border between China and North Korea to eastern Russia and Korea, but little is known about the role of the local population in the production and movement or exchange of this important raw material. This paper addresses this data lacuna by presenting sourcing results of 440 artifacts from 18 Late Paleolithic sites located in northeast China. A portable XRF enabled rapid non-destructive characterization of samples. The results show that although Paektusan obsidian was widely transported throughout northeast Asia, material from at least three other sources was also used. In particular, we highlight the significance of basaltic glass artifacts with the same geochemistry as sources found in the Primorye region of Far East Russia in sites from northeast China. This result indicates a two-way movement of volcanic glass artifacts between Primorye and the northeast of China rather than a unidirectional long-distance exchange system originating from Paektusan Volcano.  相似文献

Wang, X., Wang, J. & Zhang, J., May 2016. First appearance datum of the Silurian graptolite Oktavites spiralis, and its evolution on the northern margin of South China. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Graptolites represent the standard tools for biozonation and correlation of Ordovician and Silurian strata. Oktavites spiralis, one of the index graptolite species of the Telychian Age (late Llandovery, Silurian), is of great significance in biostratigraphy. However, the broad definition of the species and the lack of data on its evolutionary changes have led to controversies regarding its stratigraphic range and, consequently, to difficulties in regional correlations. Recent investigations in multiple Telychian profiles in the Ziyang–Langao area, along the northern margin of South China, reveal that the first appearance datum of Oktavites spiralis is located at the base of the Spirograptus turriculatus Zone, and its last appearance datum lies at the top of the Cyrtograptus lapworthi Zone (Telychian stage). The thecae vary markedly up-section and such change is consistent across all studied sections. This morphological change can be used as the basis for accurate stratigraphic subdivision and, hence, for effective regional correlation. In addition, this species has a wide range in population size and population density relative to other coexisting graptolite species, and can be better distinguished by using a more precise set of criteria.  相似文献

谷水与洛阳诸城址的关系初探   总被引:1,自引:0,他引:1  
王炬 《考古》2011,(10)
洛阳盆地群山环抱,地势险要。境内河流纵横,大的有伊、洛、、涧(谷水)四条,以它们为主干形成了密如蛛网的水道。洛阳诸水,以洛河最长,但谷水与洛阳的文化及城址变迁的关系也十分密切。目前关于谷水的研究还十分欠缺,一些学者的认识也不系统,多是先揣测地望再进行推论,结论缺乏考古学  相似文献

西汉时期列侯封地名称存在一个由“侯邑”演变为“侯国”的过程。综合利用传世文献以及印章、封泥、简牍中与列侯同名的邑类材料,可以推断西汉侯邑更名为侯国的时间在文帝三年左右。更名原因主要有西汉列侯地位逐步下降、侯邑与汤沐邑难以区分以及同名县邑增多等。侯邑更名为侯国,不只是名称的变易,还实际反映了西汉列侯性质的变迁,列侯逐渐丧失了其相对独立的地位。明确侯邑与汤沐邑的区别,可以为判断出土文献中“邑”类材料的性质、断限提供可靠依据,进一步促进汉邑问题的深入研究。  相似文献
