A perfectly preserved left felid hemimandible has been found in fluvial deposits of the Po River near Cremona (Northern Italy). The fossil, found in allochthonous position within an alluvial bar, corresponding in morphology and size at the hemimandible of modern and fossil lions. The bone, in excellent conditions, is characterized by the presence of all the teeth and shows a slight erosion of the condyle and angular process indicating a very limited transport (rafting). Based on the comparison with a large dataset of morphometric measurements of cave lion and fossil leopard hemimandibles, the studied fossil is classified as a subadult female of the chronosubspecies Panthera spelaea intermedia.

The mammalian fossil record from Po River consists predominantly of large herbivores Palaeoloxodon antiquus, Stephanorhinus kirchbergensis, Bison priscus, Megaloceros giganteus, Mammuthus primigenius, Alces alces, Cervus elaphus, some carnivores like Panthera cf. pardus, Crocuta crocuta, Ursus arctos, Canis lupus, Vulpes vulpes and primates such as Homo neanderthalensis and H. sapiens. The species composition indicates a mixing of different faunal assemblages from interglacial and glacial periods of the Late Pleistocene.

在克雷莫纳（意大利北部）附近的波河河流沉积物中发现了一种保存完好的左猫科动物易染动物。该化石位于冲积条内的异位，在现代和化石狮子的易折痕处的形态和大小都相对应。骨骼状况极佳，其特征是所有牙齿均存在，并显示出erosion突的轻微侵蚀和角突，表明运输（漂流）非常有限。根据与大型洞穴狮子和化石豹类半可适应物形态测量数据集的比较，将研究的化石归类为中年豹亚种的亚成年雌性。

来自波河的哺乳动物化石记录主要包括大型食草动物古龟，史氏Stephanorhinus，野牛priscus，巨型蝗虫，原始猛Ma象，Alces alces，Ecervus elaphus以及一些食肉动物，如Panthera cf .。哺乳动物的化石记录主要由大型食草动物Palaeoloxodon antiquus，Stephanorhinus kirchbergensis，Bison priscus，Megaloceros giganteus，Mammuthus primigenius，Alces alces，Cervus elaphus和一些食肉动物组成。pardus，Crocuta crocuta，Ursus arctos，Canis lupus，Vulpes vulpes和灵长类动物，例如Homo neanderthalensis和H. sapiens。物种组成表明晚更新世间冰期和冰期的不同动物群落混合在一起。
