Eleven wild boar remains were found in the upper Ruscinian site of Çalta: two tooth-row fragments, seven isolated teeth, a proximal radius fragment, a complete metacarpal IV. They belong to the oldest form of Sus arvernensis Croizet et Jobert, 1828, which is smaller than the nominal subspecies and possesses more simply built cheek teeth. It can therefore be allotted to Sus arvernensis minor (Depéret, 1890) which is a characteristic form of the upper Ruscinian of Europe (standard zone MN15). This form had the same ecological requirements as the recent South-East Asian wild boars of the Sus verrucosus-barbatus-celebensis group, and the much larger S. strozzii from the Villafranchian of Europe.
