介甲目甲壳动物的研究——Ⅲ.中国的六种原蚌虫

本文对栖息在我国淡水鱼苗培育池及水稻田中的6种原蚌虫(隶属于甲壳门,鳃足纲,介甲目,蚌壳虫科)进行了分类记述。其中的兖州原蚌虫Eocyzicus yanzhouensis sp.nov.及拟莱阳原蚌虫E.paralaiyangensis sp.nov.系2新种。分别列表比较了新种与其近似种佩里原蚌虫E.perrieri Daday,1914,多刺原蚌虫E.spinfer Durga Prasad et al,1981及莱阳原蚌虫E.laiyangensis Hu,1985的主要形态区别特征。文中附有6种原蚌虫的检索表及形态特征图54幅。本文记述种的名录如次: 1.东方原蚌虫Eocyzicus orientalis Daday,1914; 2.蒙古原蚌虫E.mongolianus Ueno,1927; 3.戴维原蚌虫E.davidi(Simon,1886)Brtek et al,1984; 4.莱阳原蚌虫E.laiyangensis Hu,1985; 5.兖州原蚌虫,(新种)E.yanzhouensis sp.nov.; 6.拟莱阳原蚌虫,(新种)E.paralaiyangensis sp.nov.     

Revision of the conchostracan genus Estherites from the Upper Cretaceous Nenjiang Formation of the Songliao Basin and its biogeographic significance in China

The diagnosis of Estherites corrugatus from the basal part of the Coniacian Second Member of the Nenjiang Formation in Nenjiang County, north-east China is revised following the application of a new preparation technique to some of the carapaces and an examination of specimens under a scanning electron microscope, both of which revealed morphological features on the carapace that had not been recognized previously. Restudy of the type species of the two subgenera Estherites (Euestherites) and Estherites (Parestherites) also revealed details of carapace features not seen hitherto. These indicate that they should be separated from Estherites. As a result, Euestherites is upgraded to genus level and Parestherites is placed in synonymy. The importance of Estherites and Euestherites is considered in the context of Late Cretaceous assemblages of these crustaceans and the three conchostracan provinces (South-West, South-East and North China) that are recognized to have been present in China during the Turonian–Santonian period.     

丹东地区中生代地层-古生物

丹东地区小岭组植物化石共9属12种。动物化石腹足类4属6种,叶肢介1属2种。均为首次发现。这些化石的发现为小岭组应属早白垩世而不属侏罗纪,提出了令人信服的证据。同时,阐述了古地理环境和地层特征,并与邻区进行了对比。     

A survey of the non-marine Cretaceous in China

A review of the stratigraphy of the continental Cretaceous sequences is given. Conchastracans, ostracods and charophytes have proved useful in biostratigraphy, with additional aid from pelecypods, gastropods, larger plant fossil and, locally, dinosaur remains.The continental Lower Cretaceous deposits are considered to fall into three domains: the Circum-Pacific, the Tethyan and the NW Chinese. The continental Upper Cretaceous sediments occur mainly in the three domains: NW Chinese, SE Chinese and NE Chinese.     

从叶肢介化石讨论田师傅东营坊组的时代

辽东本溪田师傅和新开岭地区出露的一套沉积碎屑岩,范国清(1982年)称为东营坊组,时代隶属晚侏罗世。本文依据 Euestheria ziliujinensis 群将东营坊组时代置于中侏罗早中期,与辽西海房沟组、冀北九龙山组叶肢介动物群主体基本一致。依据 Pagiophyllum cf.maculosum,P.cf.shahoziensis,Brachyphyllumcf.mamillare,Coniopteris sp.等植物化石和区域地层接触关系,东营坊组应置于转山子组、大堡组和三个岭组之上。     

辽东苏子河盆地叶肢介化石

本文描述的叶肢介化石是采自辽东中生代苏子河盆地的小岭组、梨树沟组和聂尔库组。小岭组产Eosestheria(Allestheria);梨树沟组产Yanjiestheria;聂尔库组产Orthestheria,Orthestheriopsis。Yanjiestheria,Neodiestheria。梨树沟组、聂尔库组所产化石为典型的延吉叶肢介群分子,属旱白垩世当无疑议。小岭组的时代从伴生的其它门类化石看亦归属早白垩世为宜。苏子河盆地所产叶肢介为延吉叶肢介群,故梨树沟组、聂尔库组与辽西九佛堂组和阜新组不能对比,这是因为辽西九佛堂组所产叶肢介为东方叶肢介群,其层位应在延吉叶肢介群之下。
