A restudy of Oryctocephalus indicus (Reed, 1910)

Restudy on morphology of Oryctocephalus indicus (Reed, 1910), based on specimens from Guizhou, China and Nevada USA, suggests that the subspecies regarded previously as Oryctocephalus indicus indicus (Reed, 1910), O. indicus latus Zhao et Yuan 2002, and O. indicus kobayashi Saito, 1934, are synonymous, and Oryctocephalus americanus Sundberg et McCollum, 2003 is a similar form of O. indicus. Oryctocephalus indicus is rediagnosed as having a glabella that is subconical in outline and tapering forward slightly; a thorax that comprises 12 segments, and a small pygidium that bears 2?3 axial rings with a terminal piece and a postaxial ridge. Oryctocephalus indicus is widely distributed in eastern Guizhou and ranges through a great interval of Kaili Formation. Its first appearance is almost identical with these events of trilobite extinction-recovery occurring at the end of the Early Cambrian, the alternation of acritach assemblages, the change of trace elements (REE) and stable isotopes (carbon) at the Wuliu-Zengjiaya section. As one of the key forms for defining the traditional Lower - Middle Cambrian boundary (the base of Cambrian Series 3 and Stage 5 in the new Cambrian chronstratigraphic standard), O. indicus has received detailed study and has more advantages than other species such as Ovatoryctocara granulata Tchernysheva, 1962 or Arthricocephalus chauveaui Bergeron, 1899.     

中亚石器文化研究综述--兼论中亚旧石器时代早期文化

中亚旧石器时代早期文化是指距今300—200万年至30—20万年前的史前人类文化遗址。这表明在很久以前原始人类就开始在中亚地区生息繁衍。在此期间，他们开始制作简单的打制石器，过着采集和狩猎的生活。     

A restudy of Oryctocephalus indicus (Reed,1910)

Since both Chinese[1]and American Palaeontolo-gists[2]proposed separately to mark the beginning ofthe Middle Cambrian based on the first appearancedatum (FAD) ofOryctocephalus indicus[3]in thesame year ,the suggestion has been considered seri-ously and adoptedfrequently[4—18].The InternationalSubcommission on Cambrian Stratigraphy (ISCS) hasorganized the Working Group,chaired by L.B. Mc-Collum,to select candidate sections that bear poten-tial to become a GSSPfor the traditional Lowe…

A new section of Kaili Formation (Cambrian) and a biostratigraphic study of the boundary interval across the undefined Cambrian Series 2 and Series 3 at Jianshan, Jianhe County,China with a discussion of global correlation based on the first appearance datum of Oryctocephalus indicus(Reed,1910)

A trilobite biostratigraphic study of a new section of the Kaili Formation at Jianshan,Chuandong Village,Jianhe County,Guizhou is reported.Additional occurrences of key species associated with the Ovatoryctocara granulata-Bathynotus holopygus Zone and the overlying Oryctocephalus indicus Zone that were originally defined from the trilobite assemblages at the Wuliu-Zengjiayan section of the Kaili are reported from this new section.The first appearance datum (FAD) of Oryctocephalus indicus occurs at the 44.52 m above the base of the unit.Based on study of abundant specimens (n = 800) from the Kaili Formation,we argue that Oryctocephalus indicus is a widespread taxon with a global distribution.O.Reticulatus (Lermontova,1940) from the middle part of the Kounamkites Zone of the Amganian Stage in the Molodo River region of Siberia and O.Americanus (Sundberg and McCollum,2003) from Nevada,North America are similar to representatives of O.Indicus which occur in the O.Indicus Zone of the Kaili Formation.O.Reticulatus and O.Americanus are here synonymized with O.Indicus (Reed,1910).This study strengthens the Wuliu-Zengjiayan section of the Kaili Formation as a candidate section for a Global Stratotype for the base of the unnamed Cambrian Series 3.     

阿拉伯人对中亚的征服以及与中国的冲突

唐前期,中亚实际上属于中国的版图,唐对中亚采取羁縻统治政策.7世纪中叶,阿拉伯人侵入中亚,与唐朝军队发生了冲突,唐军大败,中国势力退出中亚,与阿拉伯人友好相处.研究这段历史,对我们正确认识唐朝与中亚各国及其阿拉伯帝国的关系,珍视现在与中亚各国的睦邻友好,发展与阿拉伯世界的友谊都具有重要意义.

英俄角逐中亚与1887年阿富汗西北边界协定

19世纪晚期,英俄为瓜分中亚而在阿富汗激烈角逐.1887年《英俄勘分阿富汗西北边界协定》虽在一定程度上缓解了英俄在中亚的紧张对抗,却牺牲了阿富汗的领土主权,更助长了沙俄的扩张势头.     

试析美国南亚战略变化的四个阶段

南亚地区具有重要的战略地位,美国与印度和巴基斯坦的关系充分反映了美国的南亚战略.美国与印巴两国关系的变化自印度独立以来经历了美巴轴心、印巴均衡、扬印抑巴、重巴顾印等四个不同阶段.通过对这四个阶段的分析,可以得出这样一个结论:美国的南亚政策是出于维护其全球战略利益的考虑,而远非维护地区和平.     

Oryctocephalops和Ovatoryctocara在我国台江的发现及意义

台江八郎、丹寨岩英等地的中-下寒武统凯里组下部地层中，发现了广泛分布于西伯利亚中寒武统下部的Oryctocephalops Lermontova，1940和Ovatoryctocara Techernysheva 1962.这一发现使Oryctocephalops及Ovatoryctocara分布的时代下限延伸至下寒武统顶部，分布范围扩大至亚洲南部；根据这一发现及原有Oryctocephalops和Ovatoryctocara的报导，推测该两属可能在早寒武世晚期起源于我国西南地区；它们的发现还使早寒武世亚太生物大区和西伯利亚过渡生物大区的差异减小，具有古生物学及古地理意义。

《亚细亚狂人》的跨国族同理心

无名氏在1946年着手撰写《无名书》,小说提出的“星球哲学”与“地球农场”表现出鲜明的世界主义精神。世界主义精神在无名氏的《亚细亚狂人》里其实已经萌芽,它以跨国族同理心的形式展现在《露西亚之恋》和《狩》的章节之中。《亚细亚狂人》见证了无名氏作品中世界主义精神渐趋成熟的过程,是研究解读《无名书》的重要参考。     

Speciation of the genus Arthricocephalus Bergeron, 1899 (Trilobita) from the late Early Cambrian and its stratigraphic significance

The genus Arthricocephalus Bergeron, 1899 is revised, and Halipanktos Balker & Peel, 1997 is suggested here as a senior synonym. The subgenus Arthricocephalus (Arthricocephalites) Chien & Lin in Lu et al. , 1974 is considered as a separate genus. Of the 20 previously assigned species of Arthricocephaius (Arthricocephalus) Bergeron, 1899, Arthricocephalus (Arthricocephalites) Chien & Lin in Lu et al. , 1974, Arthricocephalus (Euarthricocephalus) Ju, 1983 are lumped into eight species. The speciation trend of Arthricocephalus and Arthricocephalites is demonstrated based on their stratigraphic occurrences. It not only enhances the resolution of the biostatigraphic zonation in the uppermost Lower Cambrian, but also represents a potential candidate to define the Duyunian stage. The base of the stage is suggested at the first appearance datum (FAD) of Arthricocephalus chauveaui Bergeron, 1899 within the evolutionary lineage from Ar. jiangkouensis Yin in Yin & Li, 1978 to Ar. chauveaui in a global scale.     

On the horizon of Protopteryx and the early vertebrate fossil assemblages of the Jehol Biota

Protopteryx, a monotypic fossil bird discovered from the Sichakou basin in Fengning, Hebei, is the most primitive enantiornithine currently known. The bird-bearing strata do not contain the index fossils of the Yixian Formation in western Liaoning; the fish and bird fossils have more primitive features than the related forms found in the Yixian Formation, and the conchostracans are those usually distributed in the Dabeigou and Dadianzi formations in northern Hebei. Besides, the Protopteryx-bearing strata underlie the deposits bearing the index fossils of the Yixian Formation in the neighboring basin. Thus, it could be confirmed that the horizon of Protopteryx should be lower than the Yixian Formation, and is approximately equivalent to the Dadianzi Formation in northern Hebei. This is the lowest horizon of the known fossil birds in China and Mesozoic enantiornithine birds in the world. Accompanying Protop- teryx, there are other birds, acipenseriform fishes, salamanders, and mammals, which compose the Peipiaosteus fengningensis-Protopteryx fengningensis assemblage. This new assemblage traces the vertebrate evolution history of the Jehol Biota back to 130.7 Ma before. It is suggested that the de- marcation of the Jehol Biota should be based on the large-scale tectonic-sedimentary cycles, and Peipiaosteus, instead of Lycoptera, could be taken as the vertebrate representative of the Jehol Biota.

陕西洛南陶湾砾岩地震机理新认识

陶湾砾岩是水下地震机理作用下所形成的一套碎屑岩组合。发育有典型的震积岩、海啸岩、震浊积岩及震火山岩岩石类型。其中震积岩由震褐岩、震裂岩及自碎（屑）角砾岩组成。震浊积岩分布于洛河韧性剪切构造带之南，属传统“陶湾砾岩”范围和涵义，即为狭义陶湾砾岩；而广义陶湾砾岩包括分布于洛河韧性剪切构造带之北的震积岩，海啸岩及狭义陶湾砾岩。陕西洛南地区首次发现的震积岩-海啸岩-震浊积岩-震火山岩-正常背景沉积地震沉积序列之完整在所报导古地震作用沉积序列当中实属罕见，为华北地块南缘造山过程及深入了解古地震作用提供了良好地段和有力证据。     

A new fossil genus of Mesosciophilidae （Diptera, Nematocera） with two new species from the Middle Jurassic of Inner Mongolia, China

A new genus within the family Mesosciophilidae,Jurasciophila gen.nov.,with two new species,J.curvula gen.et sp.nov.and J.lepida gen.et sp.nov.,are described and illustrated.They are established based on fossil specimens with bodies and complete wings.All of them were collected from the late Middle Jurassic Jiulongshan Formation of Daohugou in southeastern Inner Mongolia,China.Comparing with two known genera,Mesosciophilina (Kovalev,1985) and Mesosciophilopsis (Blagoderov,1994),the new genus has transitional characters.The distribution pattern of Mesosciophilidae is briefly discussed.
