甘肃兰州盆地咸水河组下红泥岩中的小哺乳动物化石

兰州盆地咸水河组下红泥岩共产有15属25种哺乳动物化石。位于下红泥岩中部的峡沟和上西沟等地产有11属20种化石（Amphechinus cf. A. rectus, A. cf. A. minimus, Amphechinus sp., Soricidae indet., Sinolagomys kansuensis, S. cf. S. major, Yindirtemys grangeri, Y. xiningensis, Y. ambiguus, Eucricetodon sp., Tachyoryctoides? sp., Parasminthus asiae朿entralis, P. tangingoli, P. parvulus, Parasminthus spp., Sinosminthus sp., Heterosminthus lanzhouensis, Litodonomys huangheensis和Didymoconus berkeyi）,被称为峡沟动物群。其中8属11种与党河Taben朾uluk动物群共有。两者的时代大致相当,为晚渐新世。位于瞿家川附近的下红泥岩下部产有：Desmatolagus cf. D. gobiensis, Ordolagus sp.,Tataromys plicidens, Tsaganomys altaicus, Amphechinus cf. A. minimus和Sinolagomys kansuensis等。该动物群的面貌显得比峡沟动物群的要老,而与其下的黄砂岩中所产的南坡坪动物群较相似,其时代有可能为早渐新世晚期。如果更多的化石证明是这样,那么在兰州盆地同一时代的同一动物群可产于不同的岩层（黄砂岩和下红泥岩下部）,而代表不同时代的不同的动物群产于同一岩性地层中。早、晚渐     

西藏北部安多地区中侏罗统(巴通阶-卡洛夫阶)菊石

最近从藏北安多地区中侏罗统发现较丰富的菊石类化石,巴通期的菊石有OxyceritesoppeliElmi,Ho moeoplanulitescf. homoeomorphus(Buckman),H. cf. acuticosta(Roemer), Choffatiacf. vicentiMangold, Siemiradzkiacf. matisconensis(Lissajous), Proceritessp., Neuquenicerascf. yokoyamaiKobayashiandFukada和Indosphinctessp.。卡洛夫期的菊石有Oxyceritescf. subcotarius(Oppel), Macrocephalites? sp., Homoeoplanulitescf. furculus(Neumayr),Indospinctes(Elatmites) cf. reveliMangold和Reineckeitessp.。其中Indosphinctes,Indospinctes(Elatmites),Neu queniceras,Siemiradzkia和Procerites等属(或亚属)在西藏北部地区为首次报道。安多地区中—晚巴通期和早卡洛夫期菊石动物群凸现较强的地方性色彩; 晚巴通期ORBIS菊石带和早卡洛夫期KOENIGI菊石带是藏北地区菊石动物群扩散的重要时期。     

越南下龙湾石炭纪巴什基尔期Pseudostaffella(筵)类动物群

作者报道了越南下龙湾地区的一个(筵)类动物群,该动物群产于下龙湾吉婆岛东的一个小岛的石灰岩地层中,其中以Pseudostaffella为主,Eostaffella次之.文中描述7个种,即:Pseudostaffella composita,P.subquadrata vozhgalica,P.antiqua,P.antiqua grandis,Eostaffella postmosquensis,E.mosquensis及E.galinae,其中以Pseudostaffella composita最为丰富,可称之为Pseudostaffella动物群.该动物群层位高于下龙湾地区Bacson组中的Millerella-Eostaffella带,相当于宾夕法尼亚系巴什基尔阶上部,中国贵州盘县滑石板阶层型剖面的Pseudostaffella composita-P.paracompressa带,俄罗斯下巴什基尔阶Prikamsky层的Pseudostaffella prae-gorskyi-Profusulinella staffellaeformis带的一部分,以及北美宾夕法尼亚系莫洛阶Millerella带与阿托克阶Profusulinella组合带之间的Pseudostaffella和Eostaffella的化石层.下龙湾Pseudostaffella(筵)类动物群的发现具有重要的地层学和古生物学意义,它对于进一步认识该地区地质演化及古生物地理变迁均有裨益.     

贵州台江中寒武世的一些软舌螺化石

甘肃兰州—第三纪中期哺乳动物化石地点

兰州皋兰山北坡新发现一小哺乳动物群,计有短面蝟类 Metexallerix gaolanshanensis gen. et sp. nov.,梳趾鼠类 Tataromys suni, T. grangeri, T. sp., Leptotataromys cf. gracilidens 和圆柱鼠类 Tsaganomys altaicus. 其时代可能相当于欧洲的 Aquitanian 期.按照现今地质年代的划分,它应划入早中新世.皋兰山短面蝟的发现表明在大约距今21百万年前后亚洲和北美之间有过动物群交流事件.     

滇东北大关地区志留纪兰多维列世晚期(Telychian期)的四射珊瑚动物群

贵州罗甸县罗悃剖面石炭系巴什基尔阶-莫斯科阶界线研究北大核心CSCD

贵州罗甸县等地发育宾夕法尼亚亚系巴什基尔阶—莫斯科阶的斜坡相沉积地层,含丰富的■类和牙形刺化石。作为莫斯科阶底界重要生物地层标志的牙形刺Streptognathodus expansus,Idiognathoides postsulcatus以及■类化石Profusulinella (Aljutovella) aljutovica,Pro.prisca和Eofusulina在该剖面上均有发现。通过对罗悃剖面宾夕法尼亚亚系巴什基尔阶-莫斯科阶界线附近■类以及牙形刺分布情况的研究,本文采用Idiognathoides postsulcatus的首现(116.8m)作为罗悃剖面莫斯科阶底界的生物地层标志,■类Profusulinella prisca和Pro.aljutovica最早出现的层位与之相近,可以作为界线的辅助标志。

新疆库鲁克塔格上奥陶统杂土坡组叶月贝动物群的发现*

叶月贝腕足动物群是晚奥陶世海洋较深水底域中一个重要的底栖壳相动物群。文中首次报道了在新疆东南部库鲁克塔格地区却尔却克山上奥陶统杂土坡组发现的叶月贝动物群,包括腕足动物5属5种(含两个未定种),分别为:Apatobolus cf.plicatus,Lingulellasp.,Foliomena xinjiangensis,Kassinella(Kassinella)cf.tchingisensis和Eoplectodonta sp.。壳相化石与笔石共同产出,保存在深灰色泥岩中,推测大致相当于BA5甚至稍深的底域环境。在同一条剖面上,叶月贝动物群曾报道于层位稍高的银屏山组[上奥陶统凯迪阶(Katian)上部],二者之间可能存在分类学和古生态学的联系。叶月贝腕足动物群在塔里木板块的持续发育为深入开展这一古板块的古地理重建提供了依据。     

南澳大利亚沃伯顿盆地Gidgealpa一号钻孔寒武系(鼓山阶)的三叶虫（英文）

描述采自南澳东北部全地下沃伯顿盆地的Gidgealpa一号钻孔23号岩芯的寒武系第三统碳酸盐前缘斜坡相动物群,有11个球接子类群,包括新种Raragnostus shergoldi sp.nov.,和14个多节类三叶虫群,包括新种Dorypyge gidgealpaensis sp.nov.,Amphoton zangi sp.nov.,Solenoparia gatehousei sp.nov.和Lisania changi sp.nov.。在澳大利亚北部生物地层范围内,这一动物群隶属Undillan(Ptychagnostus punctuosus带,Doryagnostus deltoides带和Goniagnostus nathorsti带),并且可与江南斜坡带的P.punctuosus带和G.nathorsti带对比。     

西藏拉萨地块中部扎布耶茶卡一带中二叠世(蜓)类动物群及其古生物地理意义

对拉萨地块中部扎布耶茶卡北岸的两个剖面开展(虫筳)类动物群系统古生物学及古生物地理研究。鉴定出(虫筳)类 6 属 16 种,包括Yangchienia tobleri Thompson,Yangchienia haydeni Thompson,Chusenella brevipola (Chen),C. schwagerinaeformis Sheng,C. cf. brevis (Chen),C. sp.,Nankinella rarivoluta Wang,Sheng and Zhang,N. complanata Wang,Sheng and Zhang,Kahlerina tenuitheca Wang,Sheng and Zhang,K. pachytheca Kochansky-Devidé and Ramovs,Verbeekina americana Thompson, Wheeler and Danner,V. tenuispira Sheng,Neoschwagerina cheni Sheng,N. colaniae Ozawa,N. craticulifera (Schwager),N. brevis Thompson,Wheeler and Danner。基于Kahlerina属的出现及Neoschwagerina属的厚壁壳体以及第二旋向副隔壁发育较弱的形态特征,判断其时代为二叠纪瓜德鲁普世(Guadalupian)沃德期(Wordian)。该(虫筳)类动物群面貌可与拉萨地块的狮泉河地区、措勤夏东地区、申扎地区、林周地区等对比。拉萨地块从中二叠世开始普遍出现暖水(虫筳)类动物群,这与印度板块北缘特提斯喜马拉雅地区中、晚二叠世时期均以冷水的腕足生物群为主所反映的水体性质有明显的差异。这表明拉萨地块和喜马拉雅地区在晚三叠世之前仍然连在一起的可能性并不大,拉萨地块可能在瓜德鲁普世沃德期以前已经脱离冈瓦纳大陆。

云南中甸新发现的早更新世哺乳动物

描述了最近发现于横断山脉中段的一批哺乳类化石 ,具体地点位于云南迪庆州中甸县城 (香格里拉 )以南约 6km处的公路旁。这批材料包括灵长类 (Procynocephaluscf.P .wimani)、啮齿类 (Hystrixsp .)、食肉类、奇蹄类 (Equusyunnanensis)及偶蹄类 ,其中以鹿类 (Cer vavitusultimus、Eucladocerossp .、Cervus (Rusa)yunnanensis等 )和牛羊类最为丰富 ,揭示了当时一种混合的森林 -草原环境。从动物群总体面貌来看 ,这批哺乳类可与元谋人动物群相比 ,时代为更新世早期。但其中有些种类与北方早更新世类群相似 ,如真枝角鹿及羚羊等 ,表明该动物群也与北方动物群之间存在着某种生物地理上的联系。

Multiple nostalgias: the fabric of heritage in Luang Prabang (Lao PDR)

This article explores the workings of nostalgia as a major driving force in heritage‐making. Based on my fieldwork in Luang Prabang, an ancient royal town of northern Laos which became a UNESCO Listed World Heritage Site in 1995, I propose that it is necessary to disentangle the multiple nostalgic attachments which lie behind the often‐mentioned label ‘nostalgia’ from those which are not necessarily nostalgic. I explore the various engagements of diverse actors with nostalgia, and how these engagements, rooted in personal experiences, intersect with specific postures towards time, history, heritage, development, and culture. Secondly, my aim is to highlight the performative aspects of nostalgia in the fabric of heritage. I argue that, by attempting to preserve spaces, practices, and objects, UNESCO experts and national civil servants effectively transform them. Far from stopping transmission and culture mechanisms, patrimonial recognition creates aesthetic forms, historical narratives, politics of transmission, and, more generally, social configurations. I delve into the processes through which Luang Prabang has been turned into a heritage scene and a tourist attraction, and I contend that such transformation is rendered possible by the concatenation of UNESCO projects, cosmopolitan gentrification, tourism development, and state programmes.     

河南许昌灵井旧石器遗址哺乳动物群的性质及时代探讨

系统记述了在近两年从河南省许昌市灵井旧石器遗址出土的食肉目、长鼻目和奇蹄目化石:宽吻灵猫相似种(Viverra cf. zibetha)、熊未定种(Ursus sp.)、中国硕鬣狗相似种(Pachycrocuta cf. sinensis)、古菱齿象未定种(Palaeoloxodon sp.)、披毛犀(Coelodonta antiquitatis)、梅氏犀(Dicerorhinus mercki)、普通马(Equusca ballus)和蒙古野驴(Equus hemionus),并对灵井哺乳动物群的性质和年代进行了探讨,指出灵井动物群含有的北方种类较多,与北方区的很多动物群可以比较,属于北方区动物群,其生态环境为以平原草地为主,镶嵌有零散的森林,属北温带半湿润-半干旱大陆性季风气候,年平均温度似低于现在。灵井动物群中绝灭种类占44.4%,其时代应为晚更新世早期,其绝对年龄与许家窑接近,约在100kaBP。     

Early Jurassic (latest Toarcian) brachiopods from the northeastern margin of the Western Tethys (Central Iran) and their paleobiogeographical significance

Brachiopod fauna from central Iran, recorded in the upper part of the Shemshak Group and attributed to the upper Toarcian (Pseudoradiosa-Aalensis zones), are reported for the first time in Iran. The assemblage recognized includes six different taxa: Homoeorhynchia sepahanensis nov. sp., formally described in this paper, Globirhynchia subobsoleta, Pseudogibbirhynchia sp., Tetrarhynchiidae sp. indet., Monsardithyris? aff. haresfieldensis, and Zeilleria cf. leckenbyi. Analysis of faunal affinities with other paleobiogeographical regions shows a free connection of the central Iranian brachiopod fauna and wide areas of the northern shelf margin of the Tethys Ocean. This is due to an apparent disruption of bioprovinciality inferred for the late Toarcian-earliest Aalenian, congruent with a connection through the northern seaway across the peri-Laurasian epicontinental platforms.     

Fischreste (Selachii,Actinopterygii) aus der Wealdentonscholle von Lobber Ort (Mönchgut/Rügen/DDR)

A fossil fish fauna from an erratic Wealden clay deposit in the tillitic cliff of Lobber Ort (Isle of Rügen/GDR) is described (Hybodus sp.,Polyacrodus sp.,Lissodus rugianus n. sp.,Lepidotes cf.mantelli Agassiz,Lepidotes sp., Pycnodontiformes fam., gen. et sp. indet). The fauna indicates brackish-fresh water conditions and resembles those from British Purbeck and Wealden deposits and from the Wealden deposits of Hannover. The exceptional environmental features within the depositional area of the NW-European Wealden facies have obviously accelerated speciation processes within the genusLissodus Brough 1935 during the Earliest Cretaceous.
