Articulation with lower jaw very low with respect to basicranium. No anteroventral projection or keel along symphysis of lower jaws. I3 present. Upper and lower canines slender. Cingula and accessory cuspules not strongly developed on cheek teeth. Inner and outer cusps of transverse lophs on molars more distinct than in Platygonus cumberlandensis.
