Triassic conodonts were reported from Zhuganpo and “Wayao” formations, in Guanling area, Guizhou, Southwest China. The conodont fauna is characterized by the late Carnian Neogondolella polygnathiformis. Many infancy specimens of N. polygnathiformis (Budurov and Stefanov) have been found, it provides a good opportunity to study the ontogeny of this species. Two new species, Celsigondolella baiyunensis ***., Neogondolella parafoliata ***.,and a new unnamed species , are described.

The low diversity agglutinated foraminifers are recovered from the Qihulin Formation of the Longzhaogou Group in eastern Heilongjiang, China. The foraminiferal fauna consists of 9 species of 5 genera. The common members are Cribrostomoides nonioninoides (Reuss), Haplophragmoides concavus (Chapman), H. gigas minor Nauss. Although the diagnostic zonal taxa are absent in the agglutinated fauna, according to the global stratigraphic distribution of the above-mentioned species, and the associated Pseudohaploceras ammonite fauna, the foraminiferal fauna may be of a Barremian-Aptian (Early Cretaceous) age.

Based on more exquisitely preserved specimens of Markuelia hunanensis recently recovered from Middle and Upper Cambrian in western Hunan and in the light of Synchrotron radiation X-ray tomo-graphic microscopy, the developmental sequence from cleavage through organogenesis to the pre-hatching of Cambrian embryo Markuelia, especially the developmental sequence during the pre-hatching stage, i.e. from the earliest period when the scalids and tail spines only took shape to the latest period (just about hatching), is established. This developmental sequence provides a pattern of embryonic development during the pre-hatching stage, which has not been established in the living scalidophorans (priapulids, loriciferans and kinorhynchs). Thus, it not only enriches our knowledge on the embryonic development of the extant descendants of Markuelia, but also opens a new window to the evolution and development of the animal.

An angiosperm compression flora is found in Palaeogene from Lanzhou Basin and the cuticular analysis of Populus davidiana Dode in the flora is carefully made. Fur-thermore, the fossil cuticles are compared with the epidermal structures of extant Populus leaves growing in different en-vironments, i.e. moist, semimoist, and semiarid to arid cli-matic regions. The present experiments indicate that mature leaves of P. davidiana show leaf size from big to small, leaf cuticles from thick to thin and anticlinal walls of epidermal cells from faintness to clarity along with the increase of lati-tudes of the plant distributions, the climatic variation from moist to arid, the annual precipitation from more to less and the annual mean temperature from high to low. The fossil P. davidiana differs from the specimens collected from Shandan in semiarid to arid climatic regions but closely resembles the Wushan leaves in a semi-moist climatic area in a lot of fea-tures. In a word, the new research may reflect that the flora lives in a semi-moist climatic environment. The present dis-covery of compression of Paleogene Populus davidiana is of great significance to studying vegetation types, climatic and environmental changes during the primal uplifting of the Qinghai-Tibet Plateau.

In this paper, cut marks on the long bones of class Ⅱ sized animals in the Ma'anshann site are studied. Based on the location and frequencies of the long bone cut marks, the distribution characteristics are analyzed as follows: (1) cut mark frequencies in the lower layer (LL) are much higher than those of the upper; (2. in the LL cut mark frequency of the upper limbs is the highest, and that of the middle and lower limbs is lower and the lowest; (3) In the upper layer (UL) the cut mark frequency, does not spread as orderly as in the LL. The data are compared to those of the experiment and it is demonstrated that values of the LL all fall into the experimental 95% confidence intervals, and the cut mark frequencies of the upper, middle and lower limbs coincide with those of the experiment; while the values of the UL are much lower, of which, those of the humerus, femur and radius are out of the intervals, and the frequencies of the upper, middle and lower limbs are far more different from those of the experiment. It implies that the earlier hominids (of the LL) defleshed the limbs of the class Ⅱ sized animals with stone tools more completely than the later hominids. With the evidence of burning marks, it is suggested that the difference on the roasting behaviors derived the cut mark difference of the Ma'anshan UL and LL.

In 1976, a right mandible of a Mesozoic mammal was collected by Messrs. Cheng Zhengwu and Yue Zhao of institute of geology, the {2. academy of Geological sciences, from the Middle Jurassic in Lingyuan County, Liaoning Province, Northeast China (fig. 1), When they were studying the Mesozoic stratigraphy of that area. This fossil site is most probably from the same locality as that of Yabeinosaurus tenuis reported by C.C. Young in 1958. Both fossils are derived from the same horizon.
