New Early Triassic Lingulidae (Brachiopoda) genera and species from South China

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.     

Discovery of late Changhsingian (latest Permian) brachiopod Attenuatella species from South China

Cretaceous polar dinosaur faunas were taxonomically diverse, which suggests varied strategies for coping with the climatic stress of high latitudes. Some polar dinosaurs, particularly larger taxa such as the duckbill Edmontosaurus Lambe, 1917 Lambe, L. M. 1917. A new genus and species of crestless hadrosaur from the Edmonton Formation of Alberta. Ottawa Naturalist, 31: 65–73.  [Google Scholar], were biomechanically and energetically capable of migrating over long distances, up to 2600 km. However, current evidence strongly suggests many polar dinosaurs (including sauropods, large and small theropods, and ankylosaurs of New Zealand) overwintered in preference to migration. Certain groups also appear more predisposed to overwintering based on their physical inability (related to biomechanics, natural history, or absolute size) to migrate, such as ankylosaurs and many small taxa, including hypsilophodontids and troodontids. Low-nutrient subsistence is found to be the best overwintering method overall, although the likelihood that other taxa employed alternative means remains plausible. Despite wide distribution of some genera, species-level identification is required to assess the applicability of such distributions to migration distances. Presently, such resolution is not available or contradicts the migration hypothesis.     

An Early Permian brachiopod–gastropod fauna from the Calytrix Formation,Barbwire Terrace,Canning Basin,Western Australia

Taboada, A.C., Mory, A.J., Shi, G.R., Haig, D.W. & Pinilla, M.K., 12.11.2014. An Early Permian brachiopod–gastropod fauna from the Calytrix Formation, Barbwire Terrace, Canning Basin, Western Australia. Alcheringa 39, xxx–xxx. ISSN 0311-5518

A small brachiopod–gastropod fauna from a core close to the base of the Calytrix Formation within the Grant Group includes the brachiopods Altiplecus decipiens (Hosking), Myodelthyrium dickinsi (Thomas), Brachythyrinella narsarhensis (Reed), Neochonetes (Sommeriella) obrieni Archbold, Tivertonia barbwirensis sp. nov. and the gastropod Peruvispira canningensis sp. nov. The fauna has affinities with that of the late Sakmarian?early Artinskian Nura Nura Member directly overlying the Grant Group in other parts of the basin but, as with all lower Cisuralian (and Pennsylvanian) glacial strata in Western Australia, its precise age remains poorly constrained, especially in terms of correlation to international stages. Although the Calytrix fauna lies within the Pseudoreticulatispora confluens Palynozone, the only real constraint on its age (and that of the associated glacially influenced strata) is from Sakmarian (Sterlitamakian) and stratigraphically younger faunas. A brief review of radiometric ages from correlative strata elsewhere in Gondwana shows that those ages need to be updated. The presence of Asselian strata and the position of the Carboniferous?Permian boundary remain unclear in Western Australia.

从区位功能和投资环境看南京的发展走向

南京不仅是江苏省的政治、经济、文化中心,也是长江下游仅次于上海的第二大经济中心,并成为长江流域四大区域经济的中心之一,其超越省际的区域经济中心的位势正逐步得到加强。本文着重从空间区位和功能作用的角度分析南京的投资环境,进而对南京大都市的重点投资产业和空间发展前景作一些探讨。     

论中原地区在中国文明化进程中的作用和影响

本文认为,中原地区在中国文明化进程中的作用是一个逐步强化的过程,在文明化的初期阶段,这里更多的吸收了周边地区各种文化的一些因素,在夏商周时期逐步成为文明中心.作为文明中心,它的影响作用主要表现在文化和社会发展的深层次方面,即社会的观念形态和礼仪制度等方面;大多数情况下,不是体现在文化的表层层面,即物质文化产品的基本形态方面.文明中心的进一步强化,使中原文明成为了中国古代文明的基本表现形态.     

从信息网络到城市群区内数码城市的建立

人类进入21世纪后,全球经济一体化的新形势下,工业化、城市化推动了全社会信息产业的迅速发展,尤其是大城市之间的信息高速公路、因特网等计算机技术和遥感技术发展更快。本文着重探讨了三个问题:①城市空间的信息网络世界;②信息行业对城市发展的潜在作用(协作效应、替代效应、衍生效应等)以及对城市空间扩展的影响;③城市群区内数码城市的建立,促进了城市现代化。

上博简《容成氏》字词考释二则

本文讨论了上海博物馆藏战国楚竹书《容成氏》里的“酋清”的“酋”和“夹州”的“夹”两个字,认为它们古音分别和“淑”和“冀”字相近,“酋清”应当读为“淑清”,“夹州”就是文献中的“冀州”。     

国徽中的图案是谷穗还是麦稻穗

目前关于中华人民共和国的国徽图案有这样两种说法:一是国徽上的图案是谷穗,如《辞海》中指出:中华人民共和国国徽,中间是五星照耀下的天安门,周围是谷穗和齿轮。一是国徽上的图案是麦稻穗,如蒋建华主编的《中华人民共和国资料手册》中指出:中华人民共和国国徽的内容为国旗、天安门、齿轮和麦稻穗。那么,国徽上的图案到底是谷穗还是麦稻穗呢?     

明以降滹沱河平原段河道变迁研究

滹沱河是海河子牙河系最主要的支流。明清时期,滹沱河平原段善淤、善决、善徙,被称为“决不可以人力治者”。本文通过对明清相关史料的收集、分析、整理,首次对明以来滹沱河的变迁改道进行了具体详细的恢复,进而发现滹沱河在不同历史时段,其流经方向、河道稳定性、主要河患影响范围和程度都有不同的特点。据此,文章将滹沱河变迁分成四个阶段———①明初(1368年)至明正德十二年(1517年);②明正德十二年(1517年)至清顺治二年(1645年);③清顺治二年(1645年)至清同治七年(1868年);④清同治七年(1868年)至今———并对其分别进行了介绍,最后总结了明清时期滹沱河变迁的特点和规律。
