Abstract: Sediments of the Bahe and Lantian formations, Lantian area, Shaanxi Province, China , have produced a large number of mammalian fossils. This Late Miocene sequence provides evidence for a period of major changes in the physical environment of the region. The carnivoran fossils are described and analyzed herein. The following species are present: Ictitherium vitærrinum , Hyaenictitherium cf . H. wongii and Adcrocuta eximia ( Hyaenidae) , cf. Metailurus major and cf. Metailurus parvulus (Felidae). Although a difference in the composition of the carnivoran fauna is noted towards the boundary between the Bahe Formation ( lower) and Lantian Formation (upper) , the cause of this is yet to be determined.
