In this article we describe a new and excep-tionally well-preserved pterodactyloid pterosaur, Sinopterus dongi gen. et sp. nov. from the Jiufotang Formation in west-ern Liaoning Province of northeast china. The new species is referred to the family Tapejaridae, representing its first re-cord outside Brazil. It also represents the earliest occurrence as well as the most complete skeleton of the family. Some revisions are made about the family according to the mor-phological observations of the postcranial bones of Sinop-terus. Two pterosaur assemblages appear to have existed in the Jehol Group, represented by the lower Yixian Formation and upper Jiufotang Formation, respectively. The lower pterosaur assemblage shows some resemblance to that of the Late Jurassic in Solnhofen (Tithonian) by sharing members of the Pterodactylidae and Anurognathidae. The upper one shows more resemblance to that of the Early Cretaceous Santana Formation (Aptian/Albian) by comprising only pterodactyloids such as the Tapejaridae. The age of the Yixian Formation is younger than that of the Solnhofen lithographic limestone, and the age of the Jiufotang Forma-tion (Aptian) is slightly older than the Santana Formation.

A new cyamodontoid placodont is named (Pse-phochelys polyosteoderma gen. et. sp. nov.) and described based on a three-dimensionally preserved specimen. The material comes from the Wayao Member of the Falang Formation (Carnian, Late Triassic) in Guizhou Province, southwestern china. The skull of Psephochelys shows a unique combination of characteristics observed in Psepho-derma and Placochelys, and the carapace is diagnostic of a new taxon as well. The ventral dermal armor of Psephochelys differs from all other known cyamodontoids in that it comprises irregular marginal osteoderms in loose contact with each other, and gastralia between them. The cranial suture pattern is in part difficult to analyze due to apparent co-ossification of elements, or poor delimitation of sutures. This affects primarily the demarcation of the nasal from the prefrontal, and the relation between the anterior part of the parietal, posterior ends of the frontals, and postfrontals. However, the postfrontal appears to enter the

Lophialetes-like perissodactyls are endemic to central Asia, flourishing and diversifyingin the Middle Eocene. Known taxa of all these tapiroids are represented in the Arshantan,Irdinmanhan, and Sharamurunian. In 1993, a specimen representing a new species wasfound in the Early Eocene deposits of the Wutu Basin, Shandong Province, china. Thisfossil. may be the earliest type of the Lophialetidae. Associated with it were Mesodmops(Multituberculata), Changlelestes (Soricomorpha), Alagomys, Acritoparamys (Rodentia),carpolestid primates, and Homogalax-like tapiroid etc.

The close relatives of Ctenodactylidae were present early in Eocene of Asia. As basal members of early rodents, they are important for us to understand the early history of rodents. In the present paper a new genus and species, Hohomys lii, referred to Youmyidae, and a specirnen of gen. indet., referred to Cocomyidae, are described. They were collected from Yuhuangding Formation near Wangjiazhai Village, Xijiadian Town, Danjiangkou City (formerly Junxian County), Hubei. The taxa of the vertebrate fauna associated with these two new ctenodactyloid rodents are Rhombomylus ***, R. sp., Advenimus hubeiensis, A. sp., cf. Heptondon sp.,Asiocoryphodon conicus, Heterocoryphodon flerowi and Zhongvuanus sichuanensis etc., which suggest an age of late Early Eocene.

A well-preserved pterosaur with nearly complete skull is described from the Lower Cretaceous Yixian Formation at Sihetun in western Liaoning. It is characterized by a low and long crestless skull, slender and pointed teeth, long metacarpal, nearly equal length of metatarsals I -III and short pedal digit V. It is referred to a new genus and species of the family Pterodactylidae: Haopterus gracilis gen. et sp. nov. This is the first pterosaur with a nearly complete skull from the Jehol Biota; it also represents the first non-controversial fossil record of Pterodactylidae in Asia. Haopterus is more derived than Pterodactylus from the Late Jurassic Solnhofen in Germany. This discovery extends the distribution of the family Pterodactylidae from Europe and Africa to Asia and its latest occurrence from the Late Jurassic to the Early Cretaceous. The discovery of Haopterus gracilis provides further evidence for the study of the originand radiation of the Jehol Biota; it also sheds new light on the evolution and

Mesial-distal and buccal-lingual dimensions of 1 266 hominoid teeth found in Yuanmou of Yunnan Province during the period of 1986 and 1988 have been measured. The statistical analyses of the metric data show that the tooth sizes of Yuanmou hominoid can be divided into big and small two types, and most tooth dimensions display obvious bimodalities in both histograms and 2 dimensional plots. The coefficients of variance (CV) reveal that the CVs of Yuanmou hominoid tooth sizes are within or close to the CV ranges of Lufengpithecus and extant great apes. The comparisons of tooth sizes and their proportions indicate that Yuanmou hominoids have close affinities with Lefeng and Kaiyuan hominoids, and have obvious differences with Gorilla, Chimpanzee and Orangutan. The authors believe that the hominoid fossils found in Yuanmou in the past 10 years represent a single species with highly sexual dimorphism in morphology and this species may have a close evolutionary relationship with the hominoids found in

Mitochondria experience continuous fusion and fission in a living cell, but their dynamics remains poorly quantified. Here a theoretical model was developed, upon a simplified population balance equation (PBE), to predict the morphological changes induced by mitochondrial fission and fusion. Assuming that both fission and fusion events are statistically independent, the survival probability of mitochondria staying in the fission or fusion state was formulated as an exponentially-decayed function with time, which depended on the time-dependent distribution of the mitochondrial volume and the fission and fusion rates. Parametric analysis was done for two typical volume distributions. One was Gamma distribution and the other was Gaussian distribution, derived from the measurements of volume distribution for individual mitochondria in a living cell and purified mitochondria in vitro. The predictions indicated that the survival probability strongly depended on morphological changes of individual mitochondria and was inversely correlated to the fission and fusion rates. This work provided a new insight into quantifying the mitochondrial dynamics via monitoring the evolution of the mitochondrial volume.

A new genus and species of Xenocyprininae (Eoxenocypris liui) is described from a placer gold mine northwest of Hua'nan County, Heilongiiang Province. The distribution of the extant members of the subfamily is lindted to the eastern lowlands of china and Hanoi Basin (Song Hong Valley), northern Vetnam. In Inte Chnozoic,however, in addition to their recent area of habitat they were also widely spread in Japan, mainly in the lacustrine deposits in the western side of the island arch along the Sea of Japan.

Since the Cenozoic, changes of mammals in taxonomic composition and distribution have taken place in china, mainly due to collision of plates, changes of topography and climate. The paper discusses some problems of ecology and biogeography involving the Chnese Cenozoic mammals, after the recognition of the 18 manunal ages based on nature and magnitude of the faunal changes (Tong et al.,1995).

The eggshell strength has a great influence upon hatchability. Generally, eggshells must be strong enough to withstand external pressure during incubation. It has been shown that the eggshell thinning in some kinds of birds as the result of intake of DDT or other chlorinated hydrocarbons is the cause why they were near extinction. On the other hand, eggshells need to be fragile enough to crack easily when the young hatch. If the eggshe1l strength is greater, it is hard for the young to emerge from its eggshell.
