Abstract:
在中国新近系建阶研究中，文章作者对中新统最下部的一个阶谢家阶层型剖面开展了古地磁、孢粉等方面的综合研究工作。文中是在磁性地层学的时间标尺上，着重讨论孢粉植物群的变化规律。谢家阶层型剖面中发现的孢粉组合特征，总体上与我国中新世早期的孢粉植物群变化规律相一致。但裸子植物花粉，尤其是云杉（Picea）花粉的含量在两个含孢粉丰富的样品中，由下到上明显增加，反映出研究区早中新世气候具有趋冷特征，与同期深海氧同位素变化规律可相对比。而耐旱植物，尤其是藜科（Chenopodiaceae）和蒺藜科（Zygophyllaceae）白刺属（Nitraria）花粉的含量明显降低，反映谢家期后期孢粉组合所指示的湿度具有较明显的增加，推测与东亚季风在新近纪的发展存在着一定的耦合关系。此外，蒿属（Artemisia）花粉在样品中时有见到，与其在我国新近纪地层中的分布规律相一致，与车头沟剖面古地磁的测量结果相吻合。

Abstract:
报道首次在川南甘洛田坝地区晚奥陶世晚期Hirnantian期观音桥层中发现四射珊瑚Borelasma，Crassilasma和Streptelasma等属，这一珊瑚群可与黔北毕节、仁怀地区同期的四射珊瑚群对比，进一步表明扬子区晚奥陶世晚期的四射珊瑚与北欧斯堪的纳维亚同期的珊瑚群关系密切。首次报道川南甘洛田坝早志留世的四射珊瑚Brachyelasma，Crassilasma和Entelophyllum3属，这一属群可与上扬子区重庆綦江早志留世石牛栏组或滇东北大关地区早志留世Telychian期早期嘶风崖组四射珊瑚群对比。文中还报道黔北仁怀石场晚奥陶世观音桥层2个四射珊瑚新种，即Brachyelasma concavitabulatum sp．nov．和Crassilasma obliquitabulatum sp．nov．。

Abstract:
大阳岔寒武系-奥陶系界线剖面的界线附近地层（冶里组下部）中富含海绵骨针化石，其中部分骨针化石以次生海绿石化方式保存。海绵骨针的海绿石化与骨针的原始成分蛋白石有关，蛋白石不稳定，常脱水后在成岩过程中转变为石英；在寒武纪-奥陶纪过渡时期，此地的沉积速率较小，沉积了一套海绿石凝缩层，在局部弱碱性环境中，蛋白石质的海绵骨针易于溶解，且被海绿石所替代，蛋白石的溶解与海绿石的晶出替代近为同步，致使骨针形态完好保存。海绿石化海绵骨针共有4种类型：单轴骨针，四射二轴骨针（或十字骨针），五射三轴骨针及六射三轴骨针；其中四射二轴骨针丰度相对较高。单轴骨针可能为普通海绵纲的骨针，其余骨针都为六射海绵纲的特征骨针。

Abstract:
烟叶大羽羊齿Gigantopteris nicotianae f olia Schenk是地质和古生物工作者熟知的植物化石。由于Halle（1927）曾将单网羊齿的种误归并于这一种内，致使它一度成为广见于华夏古植物区二叠纪陆相地层的植物化石。后来的研究表明（Guand Zhi，1974；姚兆奇，1983；Glasspool et al．，2004），除了河南平顶山的可疑标本外（Sze，1954），此种可作为华南冷坞期的标志性植物。最新资料证实（杨关秀等，2006），产自河南禹州和临汝上石盒子组（云盖山组）的标本完全显示了G．nicotianaefolia的特征，说明了这个种在华北的存在，从而扩大了这种植物的分布区。根据烟叶大羽羊齿的时空分布规律，文章认为河南的上石盒子组完全可与江苏龙潭组和江西乐平组老山段下亚段的含煤层位对比，时代应属瓜德鲁普世冷坞期（Capitanian）。文中较详细阐述将河南上石盒子组的时代定为冷坞期而不是晚二叠世早期（吴家坪期）的观点，并引证磁性地层方面证据，支持这一结论。

Abstract:
文中报道的拉氏大眼蟹化石（Macrophthalmus latereillei），产自浙江瑞安上望地区海滨泥鎏，为新近纪全新世的化石遗体。从沉积环境分析，进而证实这是一类穴居于海滨沿岸沙泥滩的类型。它为我国稀有的蟹类化石增加了新的记录。为探讨与周缘地区蟹类动物群的关系提供了线索。

Abstract:
The Cambrian problematic animal fossil Wiwaxia corrugata has been interpreted as an annelid,a mollusk,or a stem group of lophotrochozoan,mostly based on the proposed similarities in microstructures.This paper presents electron microscopic observations of the setae and scales of Lepidonotus helotypus Grube,1877,an aphroditiform polychaete.This taxon was chosen for microstructure study because of its scale-like structures that may be similar to the sclerites of wiwaxiids and other Cambrian animals.One specime...

Abstract:
Large bivalved arthropods are common in Cambrian strata worldwide.Among these,Tuzoia occurs in the Early and Middle Cambrian and has a wide geographic distribution.Therefore,it is significant for correlations of Lower and Middle Cambrian stratigraphy and for paleoenvironmental interpretation.Tuzoia specimens are abundant in the Middle Cambrian Kaili Biota near Balang village,Jianhe County,Guizhou Province and specimens ranging from small larva to juveniles to mature individuals are present.More than two hun...

Abstract:
全球气候在始新世总体上经历了由极热逐渐转冷的过程。植物叶片化石作为地质时期的产物，可以用来反映陆地古气候的这一变化历史。文中采用叶缘分析法首次定量重建中国始新世6个植物群的古年均温。分析结果显示，热鲁植物群（年均温17．3±3．7℃）、依兰植物群A段（年均温18．2±2．9℃）和柳区植物群（年均温22．7±2．3℃）反映了早始新世至中始新世早期气温较高。依兰植物群B段（年均温10．1±3．4℃）、石脑植物群（年均温10．1±3．4℃）、抚顺植物群（年均温5．0±1．4℃）和白鹿塬植物群（年均温9．2±3．1℃）则反映了中始新世后期至晚始新世气温明显下降的过程。植物群的古年均温推测值与植物群物种组合代表的气候类型吻合。研究表明，始新世时期中国与全球的气候变化过程基本一致，即早始新世至中始新世早期气温较高，中始新世后期至到晚始新世气温明显降低。

Abstract:
Many schemes of classification of reefs and banks have been proposed since 19 th century,some focus on descriptions of the individual cases,some on their temporal and spatial distributions.Limestones formed on reefs and banks are characterized by their complex and diverse structures that are indicative of/controlled by the original depositional environments.Ecological differentiations,thus,can be illustrated lithologically as different reef-bank subfacies.Therefore,the features of limestones can be used as ...

Abstract:
文章描述产自辽宁省北票市姜家沟中侏罗统海房沟组的叩甲化石1新属1新种，Sinolithomerus dolini gen．etsp．nov．，归入原槽缝叩甲亚科（Protagrypninae）。叩甲科化石最早发现于早侏罗世，侏罗纪是叩甲昆虫演化发展的重要阶段，在中侏罗世至晚侏罗世早期产生明显的辐射演化。晚侏罗世以前叩甲化石目前很少报道，而笔者最近几年在内蒙古道虎沟中侏罗统九龙山组发现了大量叩甲化石。因此，海房沟组叩甲化石的发现，对叩甲早期多样性、古地理分布以及地层对比提供了依据。

Abstract:
牛头岗遗址是江苏南京较大的古文化遗址，遗址文化层中植硅体组合揭示在新石器晚期（约3500Cal．aBP前），南京地区气候偏暖偏湿；商代（约3500—3000Cal．aBP），气候温暖湿润；西周早期（约3000Cal．aBP后），气候又偏暖偏湿。明显的气候波动与全新世中晚期全球气候变化可以对比。相邻何颖遗址的文化内涵和哺乳动物遗存，与牛头岗植硅体组合反映的植被与生态比较一致。新石器晚期至西周时期的气候与环境适宜古代先民的繁衍与生存，南京及滁河流域古文化内涵丰富。

Abstract:
大型双瓣壳节肢动物是凯里生物群中重要组成部分,其中吐卓虫属(Tuzoia)最为常见,化石标本达200多件.吐卓虫常见于全球早、中寒武世地层,地理分布广泛,在地层对比和古环境研究中具有重要意义.文章运用数理统计和对比研究的方法,详细检测130多块双刺吐卓虫(Tuzoia bispinosa Yuan and Zhao,1999)化石标本,发现明显可分为幼年期、青年期和成年期3个不同的生长发育阶段.文中探讨双刺吐卓虫的个体发育,确认先前建立的凯里生物群中Tuzoia的2个种:Tuzoia bispinose和T.magna,应为Tuzoia bispinose一种.
