化石产于该点剖面的柳树组中部，发现了许多哺乳动物化石，如和政羊（Hezhengia bohlini）, 甘肃黑犀（Diceros gansuensis）, 小原臭鼬（Promephitis parvus）, 副美洲獾（Parataxidea sinensis）, 翁氏鼬鬣狗（Hyaenictitherium wongii）, 巨鬣狗（Dinocrocuta gigantea）, 四棱齿象（Tetralophodon exoletus）, 贾氏三趾马（Hipparion chiai）, 渭河三趾马（H. weihoense）, 和政无鼻角犀（Acerorhinus hezhengensis）, 维氏大唇犀(Chilotherium wimani), 莫干尼伊朗犀(Iranotherium morgani), 新罗斯祖鹿(Cervavitus novorossiae), 后麂(Metacervulus sp.)，萨摩麟(Samotherium sp.), 舒氏河南兽(Honanotherium schlosseri), 羚羊(Gazella sp.)中新羚（Miotragocerus sp.）。和政羊是一种中等大小的牛，是临夏三趾马动物群中最具特色的一种。这里发现的甘肃黑犀是在亚洲发现的第一个黑犀谱系的化石物种。
Fossils were produced in the middle of the Liushu Formation in the section, and many mammalian fossils were found, such as Hezhengia bohlini, Diceros gansuensis, Promephitis parvus, Parataxidea sinensis, Hyaenictitherium wongii, Dinocrocuta gigantea, Tetralophodon exoletus, Hipparion chiai, H. weihoense, Acerorhinus hezhengensis, Chilotherium wimani, Iranotherium morgani, Cervavitus novorossiae, Metacervulus sp. ， Samotherium sp., Honanotherium schlosseri, Gazella sp., and Miotragocerus sp.。H.bohlini is a medium-sized cattle, and is the most distinctive kind of Linxia hipparion fauna.
