This study investigates the distribution of modern pollen assemblages in the Qjnghai-Tibetan Plateau, china,based on surface soil samples collected at 1202 sites along an altitudinal gradient of 10 -5500 m asl,where mean annual precipitation(MAP) ranges from 12 to 1840 mm and mean annual temperature(MAT) from -1 to 21.5℃.A total of 153 pollen taxa were found with relative abundances greater than 1%in at least two *** correspondence analysis(CCA) was used to determine the main environmental variables influencing pollen *** results reveal that MAP is the most significant dominant ***,MAT,altitude(ALT),July temperature(MT7),and relative humidity(HHH) are also significant variables that clearly follow the gradients in the CCA ordination, suggesting that pollen assemblages probably not only reflect a single climatic parameter,but also a variety of other climatic inter-related parameters. Transfer functions,based on locally weighted weighted averaging(LWWA),were developed for MAP (R-boot = 0.89,RMSEP = 109 mm),MAT(R-boot = *** = 2.3℃),ALT(R-boot = 0.73, RMSEP = 597 m),HHH(R-boot = 0.82,RMSEP = 4.5%),and July mean precipitation(MP7)(R- boot = 0.87,RMSEP = 23 ram).Overall,our results confirm that pollen can provide reliable estimates of the primary climatic *** application of the LWWA model to the fossil records of Chen Co Lake allowed quantitative inferences to be made about Holocene climatic changes in the southern Tibetan Plateau,suggesting that LWWA is a robust calibration method for quantitative palaeo-environ-mental reconstruction based on pollen data in the regions.

作者： LIU Juninstitute of vertebrate paleontology and paleoanthropology, chinese academy of sciences , beijing 100044, china institute of vertebrate paleontology and paleoanthropology Chinese Academy of Sciences Beijing China

A new sauropterygian, Anshunsaurus huangguoshuensis, is described on the basis of a well-preserved skull from the Late Triassic Wayao Member of Falang Formation, Guizhou Province, southwestern china. It is ascribed to Eusauropterygia because it possesses the following characters: the rostrum is mainly composed by the premaxillae; the nasals are small,paired and separated from one another by the premaxillae; the external nares are close to the orbits; and the frontals are fused. Anshunsaurus differs from other Triassic sauropterygians in its large size, long rostrum and the supratemporal fenestrae slightly smaller than orbits. It is further considered to be closely related to Pistosaurus on the basis of the nasals contact with the prefrontals; large pineal foramen, lain in the anterior part of the parietal table; the squamosals not in contact posterior to the supratemporal fenestra. The discovery of Anshunsaurus with the ichthyosaurs in the same locality indicates a new assemblage of Triassic marine

作者： HOU Lianhaiinstitute of vertebrate paleontology and paleoanthropology, chinese academy of sciences, beijing 100044, china institute of vertebrate paleontology and paleoanthropology Chinese Academy of Sciences Beijing China

AFTER the publication of the fossil bird Confuciusorins, additional skeletons of fossil birds have been found by Hou Lianhai, Hu Yaoming, Wang Ping, Gu Yucai and Sun Yutie in the Yixian Formation of Beipiao, Liaoning Province. The new locality is about 3 km southwest of that of Confuciusorins. Among those specimens were two of Confuciusorins and two new birds. A well-developed carina was found on the smallest specimen, a feature not found in the Jurassic birds, such as Archaeopteryx and Confuciusorins. The new Jurassic fossil bird is described in the present note.

A new ichthyosaur is named and described on the basis of two well-preserved skeletonsfrom the Late Triassic Wayao Member of Falang Formation, Guizhou Province, southwesternchina. The specimens represent a Iongipinnate ichthyosaur with a set of characters transitionalfrom the Triassic forms to the Jurassic forms. It is similar to shastasaurids of the Triassicin the relative size and shape of the limbs but resembles Ophthalmosaurus and Baptanodon ofthe Jurassic in the shape of the skull. The new taxon differs from all other ichthyosaurs found inchina in its unusual large orbit, distinct rostrum, and the hind limbs, that are slightly strongerthan the fore ones.

作者： Zhou Zhonghe (institute of vertebrate paleontology and paleoanthropology, chinese academy of sciences, beijing 100044)

In September 1990, I collected three bird specimens from the Early Cretaceous of Liaoning, china. Among them, the best one (V9769) has been published and named Cathayornis yandica (Zhou et al., 1992); the second (V9941), with only a sterflum impression, has not been referred to any known taxa yet; and the third (V9770), an incomp1etely articulated individual, is significantly different from either Cathayornis and Chaoyangia (Hou et Zhang, 1993) from the same site or any other known Early Cretaceous birds.

First Record of Protorosaurid Reptile (Order Protorosauria) from the Middle Triassic of china

A new genus and species of the family Tanystropheidae, Dinocephalosaurus orientalis gen. et sp. nov., is described based on a nearly complete skull. This is the first record of the order Protorosauria from china. It also represents the only known occurrence of Tanystropheidae outside Europe, the Middle East and North America. Dinocephalosaurus is quite similar to Tanystropheus from Monte San Giorgio, Switzerland. Primarily it is distinguished from Tanystropheus in the shape of the premaxilla, maxilla, jugal and parietal. Although the family Tanystropheidae is now referred to the order Protorosauria, the new material from china indicates that the archosauromorph affinities of tanystropheids need further investigation. The discovery of Dinocephalosaurus provides new clues for the study of the evolution and radiation of Protorosauria and Tanystropheidae. It is also important for the study of the eastern Tethyan Fauna and the paleobiogeographical relationship between Europe and southern china in the Triassic.

Distribuion of extat land vertebrates indicates that two distinct zoogeographicprovinees ekist in Chin& the Oriental Region in the sollth and the Palaearctic Regionin the north. For a long time, chna was considered part of a widespread "HtoParionprovinee" of late Miocene and Pliocene age, and distinct differentiation of faunalregions was considered to have conuneneed at the begiedng of Pleistocene time (Pei,1957; Zhou, 2964; Zhang, 1979).

古脊椎动物学报(中英文） 1995年第1期 57-60页

作者： Wu Wenyu(institute of vertebrate paleontology and paleoanthropology the chinese academy of sciences beijing 100044)

A new species of Alloptox is described in this paper. All the material was gathered from three localities (Songlinzhuang, Zhengji and Shuanggou) of Sihong County, Jiangsu Province. For detailed information on geological and stratigraphical background and others the reader is referred to Li et al. (1983) and Qiu and Lin (1986). Almost all here described 113 specimens (Songlinzhuang 68, Shuanggou 27,Zhengji 18) are isolated teeth with exception of three fragments of upper and lower jaws with few teeth. All specimens of these three localities are treated as members of one and the same population. However the measurements and figures of specimens from each locality are separately represented. The figures are represented as left ones, the abbreviated word "inv." is used under the figures of right teeth. All specimens are stored in IVPP under the inventory numbers *** present paper is one of the series studies of Xiacaowan Fauna of Miocene from Sihong. In all previous papers the fauna was assigned to Middle Miocene. Qiu et al. (1990) adapted the boundry between early and middle Miocene to the European one. Therefore Xiacaowan fauna was reassigned to Early Miocene.I am very grateful to Prof. Wang Banyue for showing me the specimens of Sinolagomys cf. ulungurensit for comparison. Thanks are due to my colleagues: *** Banyue, Tong Yongsheng, Qiu Zhuding and Zheng Shaohua who critically read the manuscript.

It has been recognized that South china is one of important distribuhon areas of theMacropetalichthvidae. Since close reatives of the Macropetalichthyidae were excusively discoveredin the Middle Paleozoic Shata of South china and Ninxia, the Study of earlyInacropetalichthyids from china is key to the reseach on the origin and evolution of theMacropetalichthytdae. In the present paper, a new genus and species of theMacropetalichthyidae, Hmptahchthy longhuaensis, is fortal from the Eariy boonianof tonghua hill, Qujing, Yunnan. The fish-haring bed lies in the top of theXuedong Fonnahon, overlain by the Chuandong Fonnaon- Zhu et al,(1994)sugpethat the age of the Xuiachong Fonnahon was Late Pragian to Eariy Eedan.
