''Palaeoloxodon naumanni'' is an extinct species belonging to the genus ''Palaeoloxodon'' that lived in Southern Japan in the late Pleistocene about 500,000 to 15,000 years ago. It is named after Heinrich Edmund Naumann who discovered the first fossils at Yokosuka, Kanagawa, Japan.
== Description ==
''Palaeoloxodon naumanni'' is closely related to the modern Asian Elephant, ''Elephas maximus''. Similar to mammoths ''P. naumanni'' had a subcutaneous fat layer and long fur〔 as an adaption to a cold environment. The species had a pair of long twisted tusks and a bulge on the head.〔 These tusks grew more than 2.4 m in length, 20 cm in diameter.〔 It was a little smaller than Asian elephants averaging to . It lived in forest which mixed subarctic conifers and cool-temperate deciduous trees.〔 The ancestor of ''Palaeoloxodon naumanni'' moved from the Eurasian continent to Japan via land bridge; it subsequently evolved independently and spread throughout Japan after the land bridge was covered by sea. ''Palaeoloxodon naumanni'' was hunted by the inhabitants of the time. Some fossils were found around Lake Nojiri (Nagano, Japan) together with a lot of stone tools or bone tools.〔
