Three early vertebrates (galeaspids Sanqiaspis zhaotongensis Liu 1975, Lungmenshanaspis yunnanensis sp. nov., and an undetermined osteolepid), were described 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), Zhaotongaspis (Wang & Zhu, 1994), Lungmenshanaspis. As to the galeaspids, the Posongchong Formation of Zhaotong District is most similar to the Pingyipo Formation of Jiangyou, Sichuan. Both Lungmenshanaspis and Sanqiaspis are exclusively found in these two regions, indicating the presence of biogeographic connection.

Dinocrocuta gigantea was erected by M. Schlosser in 1903. Since then, there were very few materials of Dinocrocuta gigantea to be found, and most of them unknown provenances. In 1986, a large quantity of Hipparion fauna fossils were yeilded in Laogaochuan, Fugu County, Shaanxi Province, among which, there are some materials of Dinocrocuta gigantea, including a complete skull, an anterior part of skull with all teeth, broken lower jaws, 10 isolate teeth, humerus and proximal part of ulna of same individual, femur etc. The skull is very big and robust, exceptionally short and width in property. The roof ascends like a flight of steps. Occipital is triangle in form and upper bor der extends posteriorly, projected over the occipital. The anterior part of upper premolar is wider than that of posterior one. The protocone of P 4 is very small. Length of Ml is longer than that of P 4 . Its limbs were discovered for first time in China. It is shown after studying that its skull is exceptionally robust but its limbs do not indicate any robust. Compared with the Hyaena sinensis, the skull of Dinocrocuta gigantea is 1.6 times wider and 1.2 times longer than that of H. sinensis, but humerus of Dinocrocuta gigantea is 1.02 times wider and 1.06 times longer than that of H. sinensis. As its geological age, most of researchers considered that Dinocrocuta gigantea was big hyaenid in Vallesian, but in Fugu it was found with a lot elements of Turolian Hipparion fauna. Preliminary paleomagnetic determination shows that the deposits contains Dinocrocuta gigantea in Fugu might be 7-8 Ma B. P.

The Chenjiawo fauna includes two stratigraphically distinct groups of mammalian fossils, 14 species of mammals and 4 stratigraphic horizons. They are L5, L6, S6 and L8— S9, representing a wide temporal distribution. The first appearance of Peking Man fauna can be correlated with Event 9 in America and Europe (Repenning, 1987 ) and is marked by the lowest stratigraphic occurrence of Cricetinus varians (LSD ). In northern Europe, Event 9 is believed to have taken place near the end of the Saale glaciation about 500 000 years ago (Bonifay, 1990 Therefore the geological age of the Chenjiawo fauna is between 500 000-1000 000 years B. P. , corresponding to oxygen isotope Stages 14-23. Through the correlation between the solid earth, atmosphere, hydrosphere, and biosphere, the boundary between the Upper and Lower Lishi Formation should be moved to the S4/L5 boundary.
