Kubanochoerus

Kubanochoerus is an extinct genus of large, long-legged suid artiodactyl mammal from the Miocene of Eurasia and Africa.
Taxonomy.
The genera "Libycochoerus" and "Megalochoerus" were once assigned to "Kubanochoerus" but are now considered distinct based on dental and minor cranial details.
The putative paraceratheriid genus "Caucasotherium", described from the Caucasus on the basis of a bone fragment with four incisors, is actually a synonym of the Middle Miocene "Kubanochoerus gigas".
Description.
The largest species, the aptly named "K. gigas", grew to be up at the shoulder, and probably weighed up to in life. The heads of these pigs were unmistakable, with small eyebrow horns, and a large horn emanating from the forehead of the males. It is speculated that the males used their forehead horns for jousting with each other.
