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.

摘要： 陕西省蓝田地区灞河组与蓝田组产出了大量的古哺乳动物化石。其中，晚中新世哺乳 动物化石序列为认识该地区自然环境的变化提供了重要的依据。详细描述和研究了其中的食肉类化石。计有鬣狗科3种（Ictitherium viverrinum、Hyaenictitherium cf. H．wongii、Adcrocuta eximia）和猫科2种(cf．Metailurus major与cf．Metailurus parvulus)。在下部的灞河组与上部的蓝田组界线附近，食肉类动物群落组成发生了改变，但引起这种改变的原因
