湖北秭归泄滩沙镇溪组底部轮藻化石的发现

晚三叠世轮藻化石在世界各地发现很少，在我国南方亦尚属首次发现。报道了秭归盆地上三叠统沙镇溪组底部的轮藻化石，计有3属4种(包括2个新种)：Stellatochara subspaerica Kozur et Reinhardt,S.xietanensis sp.nov.,Cuneatochara sanxiaensis sp.nov.,Vladimiriella decora(Saidakovsky)。根据沙镇溪组轮藻化石在国内外地质时期的分布，结合同层中所产孢粉化石的组合特征，详细讨论了含化石层位的地质时代，认为属晚三叠世早期，并对当时的古植被、古地理、古气候做了初步探讨，对化石进行了描述。

湘西震旦系留茶坡组炭质宏化石初步研究

初步研究表明,留茶坡组中部黑色页岩中化石呈炭质压膜状保存,主要包括长绳状或带状宏观藻：Chenlidenella spiralis gen.et sp.nov.,Longifuniculum dissutum Steiner,Erdtmann and Chen,1992,Longitaenina triphyllus gen.et sp.nov.,L.rhodina gen,et sp.nov.,L.lanceolatus gen.et sp.nov.;直立不分枝的管状 宏观藻Longfengshania elongata Duan et Du,1985,L.elliptic-ulum sp.nov,Paralongfengshania oblong sp.nov.Miaohenella hunanensis(Steiner,Erdtmann and Chen,1992),M.rhomba Ding,1996,M.taenina sp.nov.,Cystoculum catenuatus gen.et sp.nov.;末端存在二歧式分的丝状宏观藻：Sectoralga bibarb atus sp.nov.,S,typica Hu,1996,S.capillaceus sp.nov.,S.umbellulata Hu,1996和水母状化石Taoyuania ovatoides gen.et sp.nov.,Liaonanella giganta sp.nov.,Wulingshania canopse gen.et sp.nov.及蠕虫状化石Wenshanwania simplex gen.et sp.nov.等。从地层对比上看,上述化石可能与伊迪卡拉动物群为同一时期的产物。晚震旦世晚期留茶坡组中类水母化石的出现是我国晚震旦世生物演化史上一次重要事件,以类水母等软躯体动物和高分异度的宏观藻类共同繁盛为特色的生物群与国内外同期地层中的已知生物群面貌不同,显示出一种新的伊迪卡拉庭园,为此,本文将棋其合名为武陵山生物群。

New Early Cambrian Chordates from Haikou, Kunming

Two new chordates, Cathaymyrus haikouensis Luo et Hu sp. nov. and Zhongxiniscus intermedius Luo et Hu gen. et sp. nov. are studied in this paper. Both display numerous S-shaped myomeres on their trunk. C. haikouensis shows a long and slim body similar to that of Cathaymyrus diadexus Shu et al., Zhongxiniscus approaches to Myllokunmingia and Haikouichthys in the dorsal fin, but differs in the myomeres. Zhongxiniscus may be the intermediate form between Cathaymyrus and Myllokunmingia and Haikouichthys.

Early Evolution of Apocrita(Insecta,Hymenoptera)as Indicated by New Findings in the Middle Jurassic of Daohugou,Northeast China

<正>The classification and phytogeny of the basal Vespina(=Orussoidea+Apocrita)are reconsidered based primarily on rich and well preserved material from the Middle Jurassic of Daohugou in Inner Mongolia,China. Comparatively smooth morphological transitions are traced from a Xiphydriidae-like ancestor toward Orussoidea via the Jurassic family Karatavitidae,and through Karatavitidae and the Jurassic and Early Cretaceous family Ephialtitidae independently to Stephanidae,to Evanioidea,and,via the extinct Jurassic Kuafuidae fam.nov.to the remaining Apocrita.New hypothesis is proposed concerning development of the characteristic wasp-waist of Apocrita,which is supposed to appear independently and in different ways in Evanioidea and in the rest of Apocrita.As a result,six infraorders are proposed for the suborder Vespina with the following taxonomic structure:infraorder Orussomorpha including the only superfamily Orussoidea(Karatavitidae+Paroryssidae + Orussidae),infraorder Stephanomorpha with the only superfamily Stephanoidea(Ephialtitidae+Stephanidae), infraorder Evaniomorpha with the only superfamily Evanioidea of traditional composition,infraorder Ceraphronomorpha with the superfamilies Ceraphronoidea s.str.and monotypical Megalyroidea and Trigonaloidea,and the infraorders Proctotrupomorpha,Ichneumonomorpha,and Vespomorpha of traditional composition.The family Kuafuidae is unplaced to infraorder because it is putatively paraphyletic with respect to Ceraphronomorpha,Proctotrupomorpha,Ichneumonomorpha and Vespomorpha.Described as new are Karatavites junfengi sp.nov,Praeratavites wuhuaensis sp.nov.,P.perspicuus sp.nov.,Postxiphydria daohugouensis gen.et sp.nov.,P.ningchengensis gen.et sp.nov.,Postxiphydroides strenuus gen.et sp.nov.,Praeratavitoides amabilis gen.et sp.nov.,Proapocrtius densipediculus sp.nov.,P.sculptus sp.nov.,P.longantennatus sp.nov., P.formosus sp.nov.,P.atropus sp.nov.,P.elegans sp.nov.,Stephanogaster pristinus sp.nov.,Asiephialtites lini sp. nov.,Praeproapocritus vulgatus gen.et sp.nov.,Sinaulacogastrinus solidus gen.et sp.nov.,Sinevania speciosa gen. et sp.nov.,Eonevania robusta gen.et sp.nov.,Kuafua polyneura gen.et sp.nov.(all from the Middle Jurassic of Daohugou),as well as Kuafuidae fam.nov.including Kuafua gen.nov.as well as Arthrogaster Rasnitsyn,1975,and Leptogastrella Rasnitsyn,1975 from the Upper Jurassic of Karatau in Kazakhstan.

昆明海口早寒武世脊索动物新发现

昆明海口早寒武世筇竹寺期地层中发现两块脊索动物的化石标本：Cathaymyrus haikouensis Luo et Hu sp.nov.(海口华夏鱼）和Zhongxiniscus intermedius Luo et Hu gen.et sp.nov.(中间型中新鱼）。两者均具有明显的S形肌节，且肌隔较密。前者体细长与Cathaymyrus diadexus Shu et al.相似；后者具明显的背鳍，接近Myllokunmingia(昆明鱼）和Haikouichthys(海口鱼），但肌节构造又明显不同。中新鱼可能是华夏鱼与昆明鱼和海口鱼之间的过渡类型。

陕西镇安石炭纪四射珊瑚新属种

本文描述陕西镇安西口石门垭下石炭统顶部及中石炭统底部的四射珊瑚9属11新种。 1982年6月笔者随同中国地质科学院“石炭二叠系界线”专题研究队丁蕴杰等在陕西南部镇安县西口区石门垭测制剖面。该剖面中所采早、中石炭世四射珊瑚交由笔者鉴定。本文即为这批材料中的新属种,共9属(包括3新属、2新亚属)11新种。石门垭剖面中、下石炭统为连续沉积,岩性均为灰、浅灰色厚层灰岩。此界线上下发现有四个主要珊瑚化石层,自上而下产: 4.Acrocyathus xikouensis sp.nov.,Amandophyllum xikouense sp.nov.,Carruther-sella(Liuzhouia) shimenyaensis subgen.et sp.nov.,Koninckocarinia shaanxiensis sp.nov。,Kionophyllum sp.,Amygdalophylloides sp.和 pseudostaffella。 3.Liuia typica gen.et sp.nov.和pseudostaffella。 2.Semenoffia (pseudosemenoffia) typica subgen. et sp.nov.,Carruthersellazhenanensis sp.nov.。 1.paranemistium typicum gen.et sp.nov.,Cystilophophylloides typicus gen.et sp.nov.,C.shimenyaensis gen。et sp.nov.,C.xikouensis gen.et sp.nov,Arachnolasmaspp.,Amplexocarinia sp.,Zaphrentoides sp.,Siphonodendron sp.,Protocarcinophyllum sp. 上列层3-4内产蜓仅pseudostaffella,故时代为中石炭世早期pseudostaffella带。层1产产大量Arachnolasma种群及Protocarcinophyllum其时代定为早石炭世晚期似无疑问。层2中未采得蜓类,其时代据四射珊瑚Carruthersella的存在暂定为早石炭世末期。丁蕴杰同志给予笔者研究这批材料的机会并与夏国英、赵松银等同志共同采集化石,欧阳萱、金同安等同志给予笔者支持和帮助均此致谢。

辽宁大连震旦纪水母

1986年辽宁省地矿局区调队在大连市棋盘磨和杨家屯震旦系兴民村组发现水母类化石。本人进行了较详细的研究,根据其结构和生态特征,确定为腔肠动物门水螅虫纲水母化石,并命名为大连水母动物群。文中对其中的2个新属,7个新种进行了描述,它们为:Cyclomedusa qipanmoensis sp.nov.,Cyclomedusa stellatus sp.nov.,Medusinites monoseamoformis sp.nov.,Medusinites planodiscifo-rmis sp.nov.,Ellipsomedusa liaonanensis gen.et sp.nov.,Ellipsome-dusa dalianensis gen.sp.nov.,Quadratimedusa liaoningensis gen.etsp.nov.这一发现和研究无疑确定了大连地区震旦系的存在。     

广西隆林地区早石炭世异珊瑚类

本文描述异珊瑚类3属9种,标本采自广西隆林、隆或等地,其层位相当于贵州下石炭统大塘阶上部的Yuanophyllum带。建立新属一个Longlinophyllia(gen.nov.),新种和新亚种6个: Hexaphyllia longliensis (sp. nov.), H. gigantea crassotheca (subsp. nov.), H. tenuis longhuoensis (Subsp. nov.), Heterophyllia kitakamiensis flexuosa (subsp. nov.), H. guangxtensis (sp.nov.) 和 Longlinophyllia ditabulata (gen. et sp. nov.)。新属Longlinophyllia的隔壁和横板均可分为轴部与侧部两种类型,不同于Heterophylliidae科内的属,因此可以建立一个新科Longlinophylliidae(fam. nov.)。     

云南省晋宁梅树村地区下寒武统发现颗石藻化石

 在我国云南省晋宁县梅树村地区下寒武统发现了颗石藻化石,计有两个新属四个新种:微细管碟星藻属(新属)(Microtubediscoaster gen.nov.)包括昆阳微细管碟星藻(新属新种)(Microubediscoaster kunyangensis gen.et sp.nov.)和蜂巢微细管碟星藻(新属新种)(Microtubediscoaster honeycomb gen.et sp.nov.);始四枝碟星藻属(新属)(Eotetralithus gen.nov.)包括银杏叶始四枝碟星藻(新属新种)(Eotetralithus ginkgolabulatus gen.et sp.nov)和管柱始四枝碟星藻(新属新种)(Eotetrailthustube Pillar gen.et sp nov.).下寒武统的颗石藻化石是迄今为止世界各国已报道的最老的颗石藻化石。     

宜昌地区早志留世（Llandoverian）腕足类一新科Spinochonetidae (fam. nov.)及其意义

腕足类新科Spinochonetidae(fam.nov.)建立在宜昌地区志留系兰多维列统罗惹坪组下段中部(上埃隆阶)的Spinochonetes Rong,Xu et Yang(1974)和Spinolella(gen.nov.)两个属,以及一个属、种未定的分类单元的基础上。新科成员仅有从腹壳喙部伸出一根直的腹喙刺,这与Chonetoidea超科内的Strophochonetidae科以及Chonestrophiidae科众成员的铰合缘刺都是从腹壳铰合缘上伸出来的有着本质差别。另外,本文还对Spinochonetes以及它的属型种S.notata Rong,Xu et Yang(1974)进行重要图解和补充描述。与此同时,对Spinolella(gen.nov),以及S.minuta(gen.et sp.nov.)进行系统描述和对比。据目前所知,新科成员只分布于我国鄂西、黔东北、陕南和川北等地,属于上扬子台地的土族居民。因为Spinochonetidae(fam.nov.)属于腕足类独特的一个类型,演化快,贝体极小,保存精美,因此具有分类学、地层对比,以及恢复古环境等方面的重要意义。
