A further study of cheek teeth from individuals across the entire range supports this division and provides confirmation that "M. meles" and "M. anakuma" are indeed separate species. A further species is "Meles thorali" from the late Pleistocene, known only from fossil remains, specimens of which have been found at Saint-Vallier, Drôme, in southeastern France and Binagady, in Azerbaijan.
