Newly discovered Miocene hyaenid specimens, recently collected from the Siwalik Group, are described and discussed. A careful comparison with the known material reveals that these specimens belong to the early hyaenid species Thalassictis cf. T. proava, Ictitherine indet. and Lepthyaena sivalensis. The stratigraphic range of T. proava extended up to the Dhok Pathan Formation (Middle Miocene to Early Pliocene). The stratigraphic range of T. proava comprises the Middle to Late Miocene, with the youngest record in Hasnot, Potwar Plateau in the Siwalik Group. The material is of great interest because Siwalik carnivoran material is rare.

描述并讨论了最近从Siwalik组收集的新发现的中新世鬣蜥标本。与已知的材料，仔细对比发现，这些标本属于早期hyaenid种Thalassictis比照 普罗瓦（T. proava），叶黄素indet。和桔鳞茎。T. proava的地层范围一直扩展到Dhok Pathan组（中中新世至早新世）。普罗旺斯T. proava的地层范围包括中新世至晚中新世，最年轻的记录是Siwalik组的Potwar高原的Hasnot。该材料非常受关注，因为Siwalik肉食动物材料很少。
