Leptocoeliid brachiopods from the Early Devonian Baruntehua Formation of Dong Ujimqin Qi, northeastern Inner Mongolia were assigned to Leptocoelia by Su (1976) and Zhang(1983), and subsequently to Pacificocoelia by Hou & Boucot (1990). Transverse serial sections of Pacificocoelia sinica are illustrated hère, for the first time, based on topotype specimens. The known geographic range o Pacificocoelia is from northern China, North America, South America and Kazakhstan (Eastern Americas Realm and also occurs in east-central Asia). Atlanticocoelia is regarded hère as a junior synonym of Pacificocoelia. 相似文献

Peng, Y. & Shi, G.R., June, 2008. New Early Triassic Lingulidae (Brachiopoda) genera and species from South China. Alcheringa 32, 149–170. ISSN 0311-5518. Two new genera, Sinolingularia gen. nov. and Sinoglottidia gen. nov., together with three new species, Sinolingularia huananensis gen. et sp. nov., Sinolingularia yini gen. et sp. nov. and Sinoglottidia archboldi gen. et sp. nov., are described on the basis of a large collection of well-preserved specimens from several sections straddling the Permian – Triassic boundary in South China. 相似文献

The brissid echinoid Schizobrissus insignis (Duncan &; Sladen, 1883) is described from the Fulra Limestone (late middle Eocene), in Kachchh, India. Formerly assigned to Peripneustes or to Meoma it is shown that the species possesses a complete subanal fasciole throughout ontogeny, a characteristic feature of Schizobrissus. Eocene species of Schizobrissus and Meoma show several morphological similarities, but diverged during the late Paleogene and early Neogene. 相似文献

The article discusses the understanding of the road as a collective duty and institutionalized public space in late medieval Finland and the Swedish realm, as presented in the legislation of King Magnus Erikssons' law (landslag) of the late 1340s. After an introduction on the nature of past scholarship on the history of roads in Europe and Finland, the theoretical framework on the production and social implications of space on historical roads is discussed. The spatial understanding of the road in late medieval Finland is then studied in the context of medieval normative legislation, of which the main interest here is on King Magnus Eriksson's law, which was the major medieval law code valid in Finland. In the code, issues concerning roads and their maintenance are distributed to various sections of the law, but the main body of the legislation is set in Bygningabalken and Edsöresbalken. The analysis shows that, in the bygningabalken, the road and facilities attached to it such as bridges were rather exclusively discussed in the context of common duty, where the word common seems to be inherently understood as something obliged and insisted by the crown. In the edsöresbalken instead, the spatial dimensions of the road were brought forward in the context of the sworn peace of the realm, where the judicial space produced by the traveller was considered as a product of the road and the actual motives of travelling of the individual using it. The analysis of the respective chapters and decrees of the code shows that, from the point of normative legislation, the road was not only a recognizable space of its own but also constituted a judicial condition capable of producing distinctive social implications for those involved in the maintenance and use of roads in medieval Finland. 相似文献

The research performed by Camillo Golgi in histology and pathology dates from 1865, the year in which he obtained his MD degree, to 1923, when his last scientific article was published. Beginning in the mid-1855s, microscope manufacturers in Europe started producing objectives based on the principle of immersion introduced in 1847 by Giovan Battista Amici. The immersion objectives greatly improved the resolution of microscopic observations at high magnifications. From 1860 to 1872, technological improvements in microscope optics and the practicality of their use provided a larger community of investigators effective tools needed to study the structure of the nervous system. This progress in microscopy was associated with the application of new histological techniques, mastered by the chromoargentic reaction introduced by Golgi in 1873. In 1872, further progress in microscopy stemmed from the application of notions of applied physics to the production of microscope optics. These developments in microscopy will be briefly reviewed here. 相似文献

Analysis of the skeleton from tomb 144 of the early medieval necropolis of Vicenne‐Campochiaro in Central Italy revealed several features indicative of leprosy. The skeleton belongs to a male estimated to be between 20 and 25 years of age at death. The distal halves of the 1st and 2nd left metatarsals present acro‐osteolysis and both legs show severe subperiosteal bone reaction. The facial skeleton shows changes compatible with a chronic inflammatory process, possibly due to an infectious disease. The anatomical distribution of the lesions and their association with other skeletal lesions seems to be compatible with a near‐lepromatous form of leprosy. A differential diagnosis is made, and the skeletal traits pathognomonic of leprosy are discussed. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

西周晚期至东周之初是早期史学发展过程中的一个重要节点。受西周晚期社会政治变动的影响,该时期的历史表述产生了诸多重要变化。其一为表述主题发生转变,由原来侧重表述天命、族群及周王朝的发展,转而侧重贵族家族或诸侯功业等主题,开东周诸侯国史述作之风。其二为历史表述的内容与主旨渐趋丰富多元。西周衰亡刺激时人反思历史,审视时政,开始就历史动因提出不同的解释模式,实即私人述史的一个开端。其三为述作群体扩大,人数较多的中下级贵族及普通士阶层开始成为历史表述的主体。部分贵族士大夫摆脱旧观念的约束,就历史与政治发表看法或讴歌主君,"君子作歌"之风由此而起,实为春秋家史兴盛局面的滥觞。 相似文献

随葬礼器在墓中的区位特征对于判断随葬品的性质与用途,探求墓葬器用观念等都具有重要意义。随州叶家山、宝鸡石鼓山墓地可分别作为西周初期诸侯国与王畿地区随葬青铜礼器组合的特点的代表。结合过去发现的同时期墓葬资料可以发现早在西周初期周人已建立起一套较完备的以食器为中心的器用组合关系。就其在墓葬中的区位而言,存在着(1)按大类分置;(2)食、酒水器分置;(3)酒水器聚置,食器分置于酒、水器两端等三种情形,前两种体现出周人重食的文化特征,后一种强调酒器似与周初西迁的殷遗民有关。 相似文献
