The present author made comparisons between the mandibular fragment and teeth attached on it from longgupo,Wushan on one side,and the corresponding specimens of early \%Homo\% of East Africa,\%Homo erectus\% from Dmanisi and \%Lufengpithecus \% from Yuanmou on other *** results showed that the size of Wushan specimens are much smaller than those of early \%Homo\% of East Africa and Dmanisi mandible,and are concordant with that of \%Lufengpithecus \%from *** of the characters which have been used to attribute Wushan mandible to \%Homo \%by some scholars,are shared by both hominid and ape. Among these characters,bifurcation of the root of the premolar is one of the characters of \%Lufengpithecus\% and seldom seen in *** position of the anterior contact facet and the ratio of the length of talonid to that of the crown of Wushan premolar are characteristic in *** the ape fossils avaliable in china \%Lufengpithecus \% is the closest relative of Wushan *** they have ancestor\|descendant relation is waiting for more findings to prove.

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).

Periodicity of Retzius lines is a key factor in dental development. In this study, we examined the periodicity of Retzius lines in fossil Pongo from South china using polarized light microscope observation of dental ground sections. The periodicities all of the 15 teeth were 9 d. Comparisons of periodicity were made with extant primates, fossil apes and hominins. Periodicity of fossil Pongo from South china was relatively long but fell within the variation of extant Pongo, Gorilla and modern human, and longer than periodicity of Pan and other extant primates. Fossil Pongo from South china was similar to Lufengpithecus and Sivapithecus, shorter than Gigantopithecus and longer than European and African fossil apes and most early hominins in periodicity. Generally, the periodicities of Asian large-body fossil apes were longer than the periodicities of European and African large-body fossil apes in Miocene. Difference among species and trend of evolution in periodicity were analyzed and discussed. We found that periodicity might gradually increase from Proconsul in early Miocene to several fossil apes in Miocene and then Gigantopithecus in Pleistocene. In addition, this study made correlate analysis between periodicity and body mass respectively in males and females of six extant apes and five fossil apes, and found that periodicity positively correlated with body mass.

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.

Based on a superbly preserved skeleton, a new anuran taxon has been named and described from the Yixian Formation (Upper Jurassic/Lower Cretaceous), Liaoning Province,northeastern china. This discovery documents the first discoglossid fossil from china, the earliest record of the group in Asia, and the only second Mesozoic discoglossid known from fully articulated material in the world. The family Discoglossidae is widely perceived as a primitive anuran group, but has no definite fossils found in collaboration with their recent distribution in *** new discovery from Liaoning extends the temporal range of the group in Asia back at least 120 million years, and provides valuable fossil material for study of anatomical details of early discoglossids, as well as of historical distribution of this primitive anuran group.

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.

Three early vertebrates (galeaspids Sanqiaspis zhaotongensis Liu 1975,Lungmenshanaspis yunnanensis sp. nov., and an undetermined osteolepid ), weredescribed from the Early Devonian of Bianqinggou, Zhaotong District,northeastern Yunnan. It is argued that the fish-bearing formation could be directly correlated with the Posongchong Formation in Guangnan and Wenshan,southeastern Yunnan, and might be named as the Posongchong Formation, rather than the "Cuifengshan Formation". The Posongchong Formation of Bianqinggou yields abundant remains of early vertebrates including galeaspids, antiarchs,petalichthyids and sarcopterygians. Four genera of galeaspids have been described from this formation, i.e., Sanqiaspis (Liu, 1975; this paper), Qingmenaspis (Pan & Wang, 1981), Zhaolongaspis (Wang & Zhu, 1994 ), Lungmenshanaspis.

Up to now about 1500 forms of mammals have been recognized in the Cenozoic deposits of different ages, ranging from Paleocene to Holocene. Studies of in taxonomy,phylogeny, biogeography, and other aspects regarding these mammals are carred on actively in this country. This contribution aims to briefly summarise and update the mammal ages for the chinese Cenozoic records.
