Some limb bone fossils of a small sized bird were discovered from the brown-red sandy clay of the Early-Middle Paleocene Fangou Formation at Shimen region, Luonan County, Shaanxi Province, China. Its leg is straight, long and slender. Digit III is the longest digit but shorter than the tarsometatarsus. Hypotarsus with two narrow sulci. It is not clear whether such features as: tarsometatarsns without a foramen vasculare distale, metatarsi incompletely fused, represent primitive conditions or a juvenile stage of the bird. Therefore it is impossible to define its systematic position. It is named here Qinornis paleocenica n. gen. n. spec., incertae sedis.

A new genus and species of primitive micropternodontid soricomorph insectivores, Prosarcodon lonanensis, is described from the Paleocene Fangou Formation, Shaanxi Province, People's Republic of China. Prosarcodon lonanensis sheds new light on the origin of the mammalian family Micropternodontidae, linking them to the Palaeoryctoidea and demonstrating an early Asian oc-currence of the micropternodontids prior to theirapparent restriction to North America. The pe-trosal bone of Prosarcodon is similar to that of Palaeoryetes puereensis from the North American Paleocene. Prosarcodon and Sarcodon were both specialized in the loss of a molar, unlike the younger genus Sinosinopa from Inner Mongolia (Nei Mongol), PRC.

Chalicotherium wuduensis, n. sp., from the late Miocene of Gansu Province, China, is based on two mandibles, one an adult and the other a juvenile. This species of Chalicotherium has a relatively long diastema, short premolar row, and narrow lower molars. Canines are present, but incisors are completely lacking. The jaw is very robust with a long, thick symphysis. C. wuduensis is closest to C. goldfussi, Nestoritherium sivalense, and N. sinensebut is clearly different from all three. It is distinct from C. brevirostris, a medial Miocene Chinese species with an abbreviated snout. Differences between Chalicotheriurn and Nestoritherium seem to be part of a continuum and may not warrant generic distinction.

在陕西关中西安与咸阳地区间的河流阶地沉积剖面中采集到一批古菱齿象-披毛犀化石，在研究化石标本的基础上，作了14C年代测定及孢粉分析，研究结果揭示了该区末次冰期极盛期的气候环境特征及其演变过程：大约在距今20ka时，气候温凉偏湿，适于古菱齿象-披毛犀动物群的生存，稍后气候明显变干、变冷，许多动物难于适应而大量死亡。事实说明，末次冰期极盛期似乎存在气候环境的冷干、凉湿颤动其间的凉湿阶段似反映了北半球高纬地区Hennch事件在这一地区的记录，表明了黄土高原与极地、高纬地区的遥相关关系。

描述并比较了在陕西大荔、咸阳发现的水牛化石，一为Bubalus teilhardi，与周口店第一地点的相近；另一为B. youngi，与河南盂县的相似。水牛化石在中国的分布至今仍集中在中-东部，南、北方都有，其栖息环境与现代水牛的基本一样，生活在温暖、湿润的环境中。用支序系统学方法分析了中国化石水牛的种系发生。
