摘　　要：A lion-like pantherine felid is described as Panthera(Leo)fossilis from the late Early Pleistocene sediments of the Kuznetsk Basin(Western Siberia,Russia).The find of P.fossilis first recorded in Asia considerably extends the current notion of the eastward expansion of the most ancient lions.The Siberian lion is geologically the old­est form and is dimensionally among the largest members of the group of fossil lions on the Eurasian conti­nent.Although known by mandibular remains only,it is readily distinguished from Panthera(Leo)spelaea by a heavy built mandibular corpus with rectangular profile in the cheek teeth area,a deep,well-outlined and narrow anterior section of the masseteric fossa,and a largeр4 supported by a big unreduced anterior root.The Siberian lion shares these features with the European Middle Pleistocene P.fossilis and the American Late Pleistocene P.(Leo)atrox,which suggests their close relationship.P.atrox originated from P.fossilis and was isolated in North America south of the Late Pleistocene ice sheets.This explains why the American lion has retained more primi­tive features than the coeval Eurasian cave lion P.(L.)spelaea.
