Phytolith and pollen preserved in the Taipusi Banner paleosol profile, central eastern Inner Mongolia, provide evidence of Holocene grassland vegetation, climate and human impact. The combined phytolith and pollen records reveal a major change in vegetation composition about 5000 a BP. Before 5000 a BP, the vegetation was dominated by Aneurolepidium chinese-Stipa grandis grassland of C4 grasses. After 5000 a BP, C4 grasses rapidly retreated, indicating a shift to colder and more arid conditions. The gradual invasion of Stipa krylovii, Ag-ropyron desertorum, Ephedra, Chenopodiaceae and Caragana reveal the onset of grassland degeneration. Between 10000 and 8720 a BP, the Aneurolepidium chinese-Stipa grandis grassland included a small proportion of Artemisia shrub and Echionopos type plants, implying a strong winter monsoon and very weak summer monsoon. From 8720 to 7000 a BP, C4 grasses were common, indicating a strengthening of the summer monsoon. Between 7000 and 5000 a BP, the Holocene thermal maximum was evident, with a significant expansion of C4 grasses and the presence of some trees (such as Pinus and Betula, and so on) in or near the study site. From 4200?000 a BP, a sandy grassland of Artemisia and Agropyron desertorum together with Aster-type taxa occurred. Precipitation amelioration took place between 3000 and 2170 a BP, with a rapid development of Echinops type plants and a small expansion of C4 grasses. From 2170 a BP to present, human activities accelerated the process of grassland degeneration.

MURID RODENTS FROM THE LATE PLIOCENE OF YANGQUAN AND YUXIAN, HEBEI

23rd International Ornithological Congress

作者： Zhonghe Zhou and Fucheng Zhanginstitute of vertebrate paleontology and paleoanthropology chinese academy of sciences P. O. Box 643 beijing 100044 china.

＜正＞ Although Mesozoic birds were first discovered in china in 1982, their enormous significance did not become fully apparent until the early 1990s. Without exception, all come from lacustrine sediments in the Early Cretaceous, primarily from the Yixian Formation and the overlying Jiufotang Formation. The 40Ar/39Ar dating of the Yixian Formation suggests an age of 120-125 million years before present;the Jiufotang Formation is slightly younger.

古脊椎动物学报(中英文） 1993年第4期 284-292+333-334页

作者： Cai Baoquan(Teachers College of Zhangzhou, Fujian) Qiu Zhuding(institute of vertebrate paleontology and paleoanthropology, Academia Sinica)

Daodi is considered to be a late Pliocene locality near Nihewan, a classic site well known for its abundant and diverse Plio-Pleistocene mammalian fossils. An assemblage of micromammals was collected by the first author from eight quarries at Daodi by screen-washing in 1984. Preliminary reports on 26 species of small mammals collected and more detailed studies of lagomorphs have been given (see Cai, 1987; 1989). This paper deals with the material of the rodent family Muridae in the collections.

Large herbivorous mammals from 10 representative Quaternary localities in northeasternchina were studied. The evolution of these animals confirms Pei’s law and Bergmann’s rule. Of thethree global cold periods in the Quaternary, the first and second are not well recorded in the *** temperate period between these is well recorded. Records show that there was a sub-coldperiod (around 280 000 yr) during this temperate period. It remains to be confirmed whether thissub-cold period was limited to northeastern china. The third cold period is well recorded in theregion. The fauna in this third period were composed mostly of temperate forms, as well as typicalcold and pro-cold forms.

A comprehensive database of paleoenvironmental settings for paleoanthropological sites provides a useful tool to explore the link between human evolution and paleoenvironmental changes.A preliminary GIS-based environmental database for paleoanthropological sites in china(EDPC) was constructed based on data collected from published *** database currently contains 1114 paleoanthropological *** will be available for online access following the establishment of relevant rules,and after improvement and further development through regular and sustained updates by internal and external *** analyses using the GIS system yielded new evidence regarding human-environmental relationships.

Science in china,Ser.B 1984年第12期27卷 1296-1303页

作者：侯连海刘智成 institute of vertebrate paleontology and paleoanthropology Academia Sinica beijing

The new order of aves, Gansuiformes, is established on the basis of the fossil specimens,including a tibiotarsus and a tarsometatarsus with four complete digits derived from the LowerCretaceous of Yumen, Gansu Province. The new bird probably represents the oldest one incontinental deposits. As Archaeopteryx is now considered as the ancestor of all landbirds,Gansus, the new bird is supposed to be the ancestor of shorebirds and waterbirds. Gansui-formes is similar to Charadriformes and some waterbirds in certain characters.

SIGNIFICANCE OF THE FINDING OF CONFUCIUSORNIS AND ITS IMPLICATION ON THE ORIGIN OF BIRDS AND AVIAN FLIGHT

第二届国际古生物学大会

作者： Zhaoqun ZHANG institute of vertebrate Palaeontology and Palaeoanthropology, chinese academy of sciences, beijing 100044, china.

To understand the evolutionary history of Neogene climatic and environmental changes in East Asia, the uplift of the Tibet Plateau should be one of the most important issues. Numerous papers have been published in recent decades on this issue. The most frequently cited evidence of fossil mammals from Tibet is from the Gyirong basin (Ji et al., 1980).

作者： Hou Lianhai(institute of vertebrate paleontology and paleoanthropology, the CAS, beijing)

There are about 9,000 species of birds living in the world. They have a more or less intimate association with human life. Birds are the only vertebrates that have dwelled throughout in the air, water and land. Unfortunately, little do we understand of their origins and evolutionary history. This is largely due to the poor preservation of the fossil ancestry. Like their modem descendants, the early ancestors had both an extensive range of life spans and very thin skeletons.

In the structure of the sidewall of braincase of mammals, the advanced therians (Metatheria and Eutheria) are characterized by their peculiar property of the squamosal, which is located in the front of the petrosal and takes part in the construction of the side wall of the braincase, but all the rest of the mammals have a squamosal, which is located in the back of the petrosal without taking part in the construction of the sidewall of the braincase.
