Abstract: The genus Chilotherium was dominant among the Hipparion fauna of the Late Miocene in China, and it also appeared in other regions of Asia and South Europe widely. However, studies for the postcranial skeletons of Chilotherium are scarce. Although rich fossils of Chilotherium were discovered in Baode, Shanxi and Fugu, Shaanxi, only some postcranial bones of Ch. anderssoni were described. Recently, very abundant fossils of Ch. wimani were discovered from the Late Miocene of the Linxia Basin in Gansu, China, including a lot of skulls as well as postcranial skeletons. In this paper, limb bones of Ch. wimani are studied. The fore and hind feet of Ch. wimani are tridactyle, and limb bones are as short and robust as those of Ch. anderssoni discovered from Baode. Facets II and III for calcaneus on the posterior face of astragalus of Ch. wimani are connected to each other or separated by a narrow groove. In the subfamily Aceratheriinae, limb bones of most genera and species are longer and slenderer than those of Chilotherium, such as Plesiaceratherium gracile, Alicornops simorrense, Aceratherium incisivum, Hoploaceratherium tetradactylum and Acerorhinus zernowi. Only limb bones of Acerorhinus palaeosinensis are close to those of Chilotherium.

摘要： 大唇犀(Chilotherium 属) 是中国晚中新世三趾马动物群中占统治地位的类型,在亚洲的其他地区和南欧也有广泛的分布。然而,有关大唇犀头后骨骼的记述相当少。在山西保德和陕西府谷已经发现了丰富的大唇犀化石,但到目前为止仅有安氏大唇犀(Ch. anderssoni) 的少量头后骨骼被记述。维氏大唇犀(Ch. wimani) 最早发现于陕西府谷,被记述的材料仅包括头骨标本。最近我们在甘肃临夏盆地发现了大量晚中新世的Ch. wimani 化石,其中不仅有众多的头骨,头后骨骼也相当丰富。本文研究的标本采自临夏
