Felid material from the middle Early Pleistocene Haro River quarry, northern Pakistan, is described. Most of the material is referred to the Eurasian jaguar, Panthera gombaszogensis georgica, representing the first record of the jaguar in southern Asia. A systematic review of dental morphology of all living species of Pantherinae is made to provide a better background for studying the evolution of pantherine cats. A renewed dispersal scenario of the jaguar in Eurasia is provided. Panthera gombaszogensis georgica is suggested to be a distinct subspecies distributed in central, western and southern Asia during the Early Pleistocene, characterized by relatively small body size and slender dentition. The Eurasian jaguar does not possess the derived dental characters of the living jaguar Panthera onca (e.g. weak or no canine vertical groove, robust premolars), and presumably did not specialize on hard‐shelled prey, and therefore should be viewed as a distinct species from the living P. onca. Two additional felids from the Haro River Quarry, the large sabre‐toothed felid? Megantereon sp. and a small undetermined feline, are also reported. The Felidae faunal composition of southern Asia during the Early Pleistocene is generally similar to that of northern Eurasia, and the paleoenvironment is probably slightly more closed.

南亚欧亚美洲虎的首次记录以及豹猫之间的牙齿差异

描述了巴基斯坦北部早更新世哈罗河中部采石场的猫科动物材料。大部分材料被称为欧亚美洲虎,Panthera gombaszogensis georgica,代表了美洲虎在南亚的第一个记录。对Pantherinae所有活物种的牙齿形态进行了系统的综述,为研究Pantherine猫的进化提供了更好的背景。提供了美洲虎在欧亚大陆的新扩散情景。Panthera gombaszogensis georgica被认为是早更新世期间分布在中亚,西亚和南亚的一个独特的亚种,其特征是体型较小且牙列细长。欧亚美洲虎不具有活体美洲虎的牙齿特征Panthera onca(例如犬类垂直沟较弱或没有犬齿,坚固的前磨牙),大概不擅长于硬壳猎物,因此应被视为与活的P. onca截然不同的物种。来自哈罗河采石场的另外两只猫科动物,是剑齿状的大型猫科动物?Megantereon sp。还报道了少量未确定的猫科动物。在更新世早期,亚洲南部的费利迪亚动物区系组成与北部的欧亚大陆大致相似,古环境可能更封闭。
