记辽宁一新翼龙化石（喙嘴龙亚目）

记述了辽宁北票四合屯炒米甸子组中一新翼龙化石,该翼龙个体极小,两翼展开仅约４０ｃｍ。化石具有同形齿、长尾、极短的翼掌骨和非常发育的后肢第Ⅴ趾等特征,因而无疑可归入喙嘴龙亚目喙嘴龙科（Ｒｈａｍｐｈｏｒｈｙｎｃｈｉｄａｅ）,并代表一新属种弯齿树翼龙（Ｄｅｎｄｒｏｒｈｙｎｃｈｕｓｃｕｒｖｉｄｅｎ－ｔａｔｕｓｇｅｎ．ｅｔｓｐ．ｎｏｖ．）。该化石是我国及东亚晚侏罗世喙嘴龙类翼龙的首次记录,它的发现有力地表明包括中华龙鸟和孔子鸟在内的辽西四合屯化石层的地质时代应为晚侏罗世。

四川自贡地区侏罗纪恐龙动物群组合特征

自贡地区涵盖侏罗纪3个不同时期的恐龙动物群组合。早侏罗世是恐龙动物群的萌发阶段,以原蜥脚类和原始蜥脚类恐龙共存为主要特征,属禄丰蜥龙动物群范畴;中侏罗世蜀龙动物群具有过渡性质,代表恐龙动物群的繁荣阶段,特点是原蜥脚类绝迹,原始的蜥脚类和进步的蜥脚类共同成为动物群的主要成员,并开始出现一些特化的蜥脚类,肉食龙类和鸟脚类成为动物群的重要成员,剑龙类开始出现;晚侏罗世马门溪龙动物群代表恐龙动物群发展的鼎盛阶段,特点是成渝龟类被蛇颈龟类所取代,原始的蜥脚类已消亡,特化的长颈型的马门溪龙类为主要成员,肉食龙类、鸟脚类和剑龙类向大型化发展。自贡地区侏罗纪恐龙动物群的兴衰和更替与四川盆地古地理环境和古气候的变迁密切相关。     

Structure,Orientation and Finite Element Analysis of the Tail Club of Mamenchisaurus hochuanensis

Abstract: The structure and orientation of the posterior extremity (tail club) of the caudal vertebrae of Mamenchisaurus hochuanensis Young and Chao, 1972 from the Upper Jurassic Shangshaximiao Formation has been analyzed to determine the tail club function using Finite Element Analysis. Of the four caudal vertebrae composing the tail club, the second largest (C"1") was probably the most proximal, and is fixed with the preceding sequence of the caudal vertebrae, whereas the smallest (C"4") is free and forms the termination of the tail club. Our analysis also suggests that the tail club is more efficient in lateral swinging rather than up-and-down motion, and that the best region for the tail club to impact is at the spine of the largest of the four caudals (C"2"), with a maximum load for impact at about 450 N. The tail club of Mamenchisaurus hochuanensis probably also had limitations as a defense weapon and was more possibly a sensory organ to improve nerve conduction velocity to enhance the capacity for sensory perception of its surroundings.     

吉林九台白垩系一新的蜥脚类恐龙

记述了蜥脚类恐龙(Sauropoda)中一新的属种—西地九台龙(Jiutaisaurusxidiensisgen.etsp.nov.),包括18个相关节的尾椎及13个脉弧。化石产于吉林九台白垩纪泉头组的紫色-杂色砂岩中。其主要特征为:中部尾椎椎体两侧出现前后延长的棱脊,前-中部尾椎双凹型,神经弓位于椎体前半部,脉弧不分叉,血管孔长度约占脉弧长度的1/2以上。新属种的发现对进一步研究白垩纪蜥脚类恐龙的系统演化、古地理分布等提供了新的材料。

First record of the family Palaeolimnadiopseidae Defretin-Le Franc, 1965 (Crustacea–Conchostraca) in the Triassic of Argentina

Endolimnadiopsis rusconii sp. nov. is the first record of paleolimnadiopseid conchostracan from the lower Upper Triassic Cacheuta Formation, Mendoza Province, Argentina. An extended diagnosis of the genus Endolimnadiopsis Shen is presented, and some comments about its taxonomic position in Family Palaeolimnadiopseidae and Subfamily Asiolimnadiopseinae are also given. The paleobiological, paleobiogeographical, and evolutionary implications of this finding are briefly discussed. The find supports a close relationship between southamerican and asiatic conchostracan faunas. From an evolutionary point of view, the new species shows a combination of both characters, primitive and more advanced, that corresponds with a transitional form between primitive paleozoic to advanced mesozoic species. E. rusconii sp. nov. is compared with other paleolimnadiopseids such as Endolimnadiopsis eichwaldi Netshajev from the Upper Permian of Russia.     

The quaternary geomorphology of Scotland: The research contribution of J.B. Sissons

Between 1958 and his retirement in 1982, J.B. Sissons published some 80 articles and two books. The majority of these were devoted to aspects of the Quaternary geomorphology of Scotland, but many of his findings have much wider application. This paper reviews the six main areas in which Sissons made an outstanding research contribution. In approximate chronological order, these were as follows: (i) reassessment of the significance of meltwater channels and related fluvioglacial landforms (1958–1963); (ii) the deciphering of an extremely complex sequence of raised and buried shorelines and associated sea-level changes in eastern Scotland (1962–1972), together with reinterpretation of the age and origin of marine rock-cut platforms in western Scotland (1974–1982); (iii) work on the data banking of borehole records and the relevance of certain aspects of drift stratigraphy to engineering operations (1969–1971); (iv) research on the extent and chronology of the last Scottish ice sheet and associated readvances (1961–1982); (v) the reconstruction of the extent and palaeoclimatic implications of Loch Lomond Stadial glaciers (1972–1982); and (vi) investigation into aspects of landscape evolution in the Glen Roy area, including the formation of former lake shorelines, the catastrophic drainage of former ice dammed lakes and its effects, the interpretation of complex terrace sequences and the discovery of links between deglaciation, unloading, faulting, earthquakes and landslides (1978–1982). This paper also includes a complete list of Sissons' publications.

A New Basal Titanosaur (Dinosauria: Sauropoda) from the Early Cretaceous of China

A new dinosaur of Early Cretaceous age was recently discovered from the Mazongshan area of northwestern Gansu Province, China. The new dinosaur represents a new genus and species of Sauropoda, and is among the most basal members of Titanosauria. Its finding also suggests that titanosaurs might have originated in Asia no later than the Early Cretaceous.
