摘要：Some Pliocene mammalian fossils were collected by writers themselves and others during two field seasons in winters of 1971 and 1972 from Banguo basin in Yuanmou district, Yunnan. In the past, a part of Pliocene mammalian fossils of this district was described separately by Chow (1961)，Liu, Tang and You (1973).
The fossils were preserved in variegated clay with calcareous concretion and sands. These fossils are of important significance in stratigraphical division. The new materials are described in the present paper.
