Lynx remains from the Pleistocene of Valdemino cave (Savona, Northwestern Italy), and the oldest occurrence of Lynx spelaeus (Carnivora, Felidae)

Fossil lynxes are quite common in the Plio-Pleistocene mammal assemblages of Europe. Despite of this abundant record, the phylogeny of the genus Lynx and the relationships among the different recorded species are far from being resolved. The most controversial species of this group is Lynx pardinus spelaeus or Lynx spelaeus according to different scholars, recorded in the Middle and Late Pleistocene of France and Italy. Here, we describe unpublished remains of fossil lynxes from different layers of the Valdemino cave (Middle to Late Pleistocene, Savona, Italy). The reported evidence suggests that the lynx from Valdemino represents probably the most ancient well-documented material of L. spelaeus in Europe further reinforcing the idea of progressive size reduction and acquisition of more trenchant dentition in the European lineages of lynx (L. pardinus and L. spelaeus) during the Middle to Late Pleistocene.
