| X. Wang et al. 2023 | Eoarctos shares with Parictis, Nothocyon, and derived species of Subparictis the following derived characters: wrinkled enamel surface, cheek teeth low-crowned with bunodont cusps, robust premolars with surrounding cingula, p3 shorter and lower-crowned than p2, P4 broad relative to its length, and m2 trigonid compressed leaving a wide buccal cingulum and a protostylid. However, Eoarctos is easily distinguished from all others by its massive premolars for durophagy and hypo- carnivorous molars (molluscivore): massive horizontal ramus with a deep ventral digastric groove; P3 lingually expanded with a third root; M1-2 mesiodistal expansion of pre- and post- protocrista and enlargements of a paraconule and metaconule; narrow, lower crowned, and shortened lingual cingulum on M1–2; extreme shift of m2 trigonid to mesiolingual corner; andabsence of m3 |
