Abstract: New materials of Tungurictis spocki, a basal hyaenid (Hyaenidae, Carnivora), from the Tairum Nor locality in Tunggur Formation is described. For the first time, associated upper and lower teeth are available for this species, which is previously established on a single skull. The newly available lower molars corroborate current believes that Tungurictis is a primitive hyaenid. A relatively low metaconid and an equal height for m1 hypoconid and entoconid further establish its difference from hypocarnivorous forms such as Plioviverrops. Tungurictis spocki is probably closely related to European and western Asian Protictitherium gaillardi.

摘要： 斯氏通古尔鼬( Tungurictis spocki) 是 1939 年 Colbert 描述的一个采自内蒙古中中新世通 古尔组的小型食肉类的新属、新种。他最初认为通古尔鼬属于灵猫科 ,但最近 Hunt (1989) 及 Hunt 和 Solounias(1991) 提出通古尔鼬具有一些鬣狗科耳区的特征 (如水平方向的听泡隔板 等) 但缺少典型鬣狗科强壮的用来咬碎骨骼的前臼齿。Werdelin 和 Solounias(1991) 对鬣狗科 分支系统的研究也进一步证实通古尔鼬实际上是一种鬣狗科较为原始的成员
