Two species of Tetraconodontinae dispersed in the early Late Miocene from Eurasia into Africa. Tetraconodontinae then became the dominant pigs in the African Late Miocene and Pliocene. Although the dispersal to Africa must have come from SW Asia, no Tetraconodontinae were known from the area dating from the time of this dispersal.
In this paper, a tetraconodontine tooth from the Nuri Yamut locality near AlÇitepe in European Turkey is described. In morphology, size and in geographical and stratigraphical position this tooth is close to a form that is ancestral to part of the African Tetraconodontinae. The tooth is assigned to cf. Conohyus giganteus, one of the species that dispersed to Africa.
The dispersals of these Tetraconodontinae seem to be more or less coeval with that of Hipparion and are assumed to be allowed for by a change in global climate.
