This genus includes fossil animals from the middle and late Pleistocene of the proboscidean suborder Elephantidae, such as Naumann's Elephant (Palaeoloxodonta) and Aomori's Elephant (Elephantidae). They adapted to the temperate grasslands of Eurasia. Their cheek teeth do not have as pronounced diamond-shaped ridges as those of Loxodonta , but the tendency is still clearly visible. Hikoshichiro Matsumoto created the name as a subgenus, meaning "old Loxodon," and H. Osborn elevated it to a genus, but scholars such as Osborn who opposed the subdivision of elephants did not use it as a genus name, causing confusion in the scientific name.

長鼻目ゾウ亜目の更新世中・後期の化石動物ナウマンゾウやアオモリゾウなどを含む属である。ユーラシアの温帯草原地帯に適応した。頬歯は Loxodontaほど著しい菱形の稜はもたないが,その傾向は十分にみられる。松本彦七郎が「古いロクソドン」という意味で亜属名としてつくり,H.オズボーンが属名として昇格させたが,オズボーンをはじめとするゾウ類を細分することに反対の学者たちは属名として使用しなかったので,学名に混乱を生じていた。
