LA LEONESSA DEL PO

First fossil record of cave lion ( Panthera ( Leo ) spelaea intermedia ) from alluvial deposits of the Po River in northern Italy Original Abstract 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
