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仍有待进一步研究确定。 A large number of ancient mammalian fossils have been produced in Tahe and Lantian formations in Lantian area of ​​Shaanxi Province. Among them, the late Miocene mammalian fossil sequence provides an important basis for understanding the changes of the natural environment in the area. One of the meat-eating fossils is described and studied in detail. Three hyena species (Ictitherium viverrinum, Hyaenictitherium cf.H.wongii, Adrocuta eximia) and two cats (cf. Metailurus major and cf. Metailurus parvulus) were counted. The composition of carnivore communities has changed near the boundary between the Shihe Group in the lower part and the Lantian Group in the upper part of the boundary, but the reason for such change remains to be determined.
