福建大田崆峒山晚二叠世和早三叠世介形类

报道福建大田崆峒山晚二叠世大隆组、长兴组及早三叠世溪口组介形类35属67种,其中描述8属9种(包括5新种)。产自长兴组的介形类化石被划分为3个组合,自下而上分别是：Polylites magnituberos-Or-thobairdia meishanensis-Pustulobairdia mailinensis组合,Baitrdia urodelofot-OS-orthobairdia exilimarginata-Bairdia subcontracta组合和Petasobairdia bicornuta-Neoamphissites costatus-Kegelites datianensis组合。大田崆峒山介形类动物群在二叠-三叠系界线上下具有明显的突变性质,这与世界其它地区一样,是遭受二叠纪末期的生物大灭绝事件重创所致。根据介形类化石组合特征,并参考共生或共存化石的内容,福建大田地区长兴组大致相当于浙江煤山长兴组的中、上部,长兴灰岩下伏的海相碎屑岩应划归长兴阶。大隆组、长兴组及溪口组的岩性和化石组合特征．显示古环境从滨海沼泽开始,经历浅海盆地→浅水碳酸盐台地→浅海近岸环境的演化过程。     

福建大田崆峒山晚二叠世长兴组的牙形刺

该文记述了福建大田崆峒山晚二叠世长兴组牙形刺化石4属7种,在长兴组上部建立了Neogondo-lella changxingensis-N.deflecta-N.subcarinata组合带,着重分析了崆峒山长兴组牙形刺的分布规律和组合特征。认为该组合可与浙江煤山长兴阶上部牙形刺组合带对比;福建大田崆峒山长兴组仅大致相当于我国华南长兴阶或浙江煤山长兴组的中、上部,其下伏的原属翠屏山组海相碎屑岩应划归长兴阶。     

晚二叠世几种鹦鹉螺

中国南部的晚二叠世地层相当发育并产有丰富的菊石和鹦鹉螺化石。赵金科等(1978)曾对华南晚二叠世菊石进行较系统的研究,关于鹦鹉螺,限于标本,仅描述了部分保存较好的。近年来,在安徽、湖南、广西又陆续发现一些鹦鹉螺化石,其中有的保存相当完整,特在此文予以报道。头带角石科鹦鹉螺是二叠世常见的化石,本文新建的Nodonautilus gen.nov.与Neoclavinautilus gen.nov.即属于此类。这类鹦鹉螺的壳面往往饰有发育的肋与瘤,有时骤然一看,与假提罗菊石类有某些相似之处,如果标本好,保存有缝合线则就不难区分,因为鹦鹉螺的缝合线远较菊石的简单。 Permonautilus属系首次在我国发现,这类鹦鹉螺很特征,即在近口部处脐缘迅速向侧部     

福建大田长兴组的小有孔虫动物群

首次报道福建省大田崆峒山晚二叠世晚期长兴组中,与Palaeofusulina筵类群共生的小有孔虫动物群,计有22属64种(包含1个新种,2个未定种),称Colaniella-Pachyphloia ovata组合。通过这一动物群的研究,不但为福建地区长兴组补充了新的化石门类,且为该组的时代归属又提供一佐证,对该地区长兴组中的灰岩层古生态特征也作了简要的探讨。     

贵州西部晚二叠世鹦鹉螺

黔西晚二叠世鹦鹉螺化石,以往甚少正式报道。笔者将近年来所得标本研究,报道于下。黔西晚二叠世早期乐平(或称龙潭)阶的鹦鹉螺化石比较贫乏,本文所描述的仅二种,其中Lopingoceras sp.产于安顺轿子山龙潭阶顶部,其外形与盐岭齐德鲁组(Chhidru Formation),旧称上长身贝灰岩(Upper Productus Limestone)的“Orthoceras cyclophorum Waagen”相似,但后者壳表横环和缝合线倾斜方向相反,这一未定种与苏联阿美尼亚卓勒法地区上二叠统卓     

浙江长兴灰岩中扁体鱼化石的发现

本文记述的煤山中华扁体鱼(新属、新种)Sinoplatysomus meishanensis gen.et sp.nov.,发现于浙江省长兴县煤山晚二叠世长兴灰岩中。这一发现对于了解扁体鱼的地理和地层分布是很有意义的,丰富了我国晚古生代海相地层中的鱼化石资料。     

下扬子地区晚二叠世菊石及古生态意义

下扬子地区晚二叠世地层发育,菊石较丰富.早在卅年代前辈地质学者已开始对本区二叠纪地层进行研究.自五十年代陆续有人采集鉴定其中的菊石化石,特别是随着大规模开展区域地质调查工作,不断发现和采集到许多较好的菊石标本,为系统研究晚二叠世菊石提供了大量的实际材料.1978年赵金科、梁希洛、郑灼官发表了《华南晚二叠世头足类》专著,这对生产、教学及科研工作起到极大的指导作用.     

川西北晚三叠世的灯海绵动物群*

由于印支运动的结果,我国晚三叠世卡尼期地层分布局限。川西北广元县至什邡县分布的地台型海湾相卡尼期地层称汉旺组。此组下段含菊石Trachyceras, Protrachyceras, Clionites等,相当于下卡尼阶;该段下部厚0—37m,为海百合、钙藻生物骨屑灰岩滩相;上部厚32—91m,为亮晶鲕粒灰岩滩相。汉旺组上段含菊石Tropites, Discotropites, Hanaceras,Buchites等,相当于上卡尼阶;该段下部厚3—16m,为生物骨屑灰岩滩相;     

湖南常宁斗岭下二叠统斗岭组的一种床板珊瑚

在湖南南部常宁县斗岭下二叠统斗岭组合煤地层的顶部黑色泥岩中,发现与菊石、腕足类及双壳类动物共生的一种床板珊瑚化石,保存完好,经鉴定为Protomichelinia gangilliigerasp. nov.。 Protomichelinia常见于我国早二叠世地层中,尤其是早二叠世晚期(茅口期)发育较盛,它常与块体状的 Ipciphylium共生。据Flügel(1964)研究,在伊朗北部Mingum和Ruteh流域之东的Zarband Kuh的Ruteh灰岩中,     

那丹哈达岭早二叠世䗴类

那丹哈达岭是新发现的早二叠世(竹蜓)类产地。过去,赋存它的地层被称为“典型的燕山地槽沉积”。这套地层是厚达8000米以上的海相沉积,在1957年被中、苏综合考察队根据岩性、放射虫化石与锡霍特阿林中生代海相地层对比,定为上三叠统及下、中侏罗统。近年来我们在这套地层中发现了自中石炭世到早二叠世(竹蜓)类。本区早二叠世地层称东大沟组,岩性主要为板岩、砂岩、粉砂岩、硅质岩夹少量火山岩及灰岩透镜体或薄层,出露厚度大于330米。根

The new pollen genera and their species described herein have been compared in some details with recent pollens and considered their affinity with such recent families as Dipsacaceae, Myoporaceae, Apocynaceae and Lythraceae. According to the age of the pollen-bearing strata, a preliminary discussion is made regarding to the taxonomy of the recent plants families with which our new described pollens are related. Hence, this study may provide some mieropalaeobotanical information for deciphering 'the phylogeny of these plants.

New Genera and Species of Psychodoid Flies from the Lower Cretaceous Amber Lebanon

Until now, only two Psychodoidea were known from Lebanese amber. We describe two new genera and species of Phlebotomidae ( Mesophlebotomites hennigi gen. et sp. nov., Libanophlebotomus lutfallahi gen. et sp. nov.) and four new genera with six new species of Psychodidae ( Paleopsychoda solignaci gen. et sp. nov., Paleopsychoda jacquelinae sp. nov., Protopsychoda nadiae gen. et sp. nov., Protopsychoda hammanaensis sp. nov., Libanopsychoda abillamai gen. et sp. nov., Cretapsychoda inexpectata gen. et sp. nov.) from the Lower Cretaceous amber of Hammana/Mdeirij, Lebanon. These fossils are included in a phylogenetic analysis of the subfamilies of Psychodoidea. This superfamily was probably as diverse in the Early Cretaceous as now.

A NEW LACEWING FAMILY (NEUROPTERA)FROM THE MIDDLE JURASSIC OF INNER MONGOLIA, CHINA

Abstract  A new family, Grammolingiidae of fossil lacewings is erected, of which 3 new genera and 6 new species are described and illustrated: Grammolingia boi . gen. nov. et sp. nov., Lithlingia rhra gen. nov. et sp. nov., Litholingia eumopha gen. nov. et sp. nov. and Litholingiu polychotom gen. nov. et sp. nov., Leptolingia jurassica gen. nov. et sp. nov. and Leptolingia tianyiensis gen. noc. et sp. nov. A key to genera within this new family is provided. All specimens described were collected from the Middle Jurassic Jiulongshan Formation of Eastern Inner Mongolia, China. The present discovery demonstrates that present knowledge of the Jurassic Neuropetra fauna remains very poor. The fossil specimens are deposited in Yizhou Fossil Museum and Department of Biology, Capital Normal University, respectively.
