Outside Asian Russia, the only large Panthera (Leo) youngi (Pei, 1934) from the Peking Man site of Zhoukoudian 1, northeastern China, dated at 0.69–0.42 Ma (Qiu 2006), was referred to the lion group of pan-therine cats (Pei 1934; Harington 1969). Numerous finds of fossil lions in Asian Russia are known from the papers by Riabinin (1919), Gromo-va (1932), Vangengeim (1961), Vereshchagin (1971), Alexeeva (1980), Foronova (1982, 1999, 2001), Barysh-nikov and Boeskorov (2001), Sotnikova and Nikolskiy (2006), Baryshnikov and Petrova (2008) and Ovodov and Tarasov (2009). However, the material presented in these works mainly belongs to the Late Pleistocene Pan-thera (Leo) spelaea (Goldfuss, 1810). Middle Pleisto-cene large lion-like felids in Russia have been reported occasionally but these nds have been associated neither with the European P. fossilis nor with Asian P. youngi (Vereshchagin 1971). The assumption of the presence of P. fossilis in the Asian part of Russia was rst made by Baryshnikov and Boeskorov (2001) based on finds of very large lions’ limb bones in the Middle Pleistocene localities along the Volga and Lower Tunguska Rivers. However, the rst clear evidence of a giant lion similar to the P. fossilis–P. youngi group in Asia is a mandible described by Foronova (1998, 2001, 2005) as Panthera sp. from the Early Pleistocene of the Kuznetsk Basin in Western Siberia. The mandibular size of this felid is close to that of the largest forms of fossil pantherine cats and in some parameters (Lp3-m1)
