If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|R. H. Tedford et al. 2009||Eucyon davisi differs from E.? skinneri in its larger size; longer jaw; more elongate, taller crowned premolars; p4 with second posterior cusp; m1 trigonid relatively longer, protoconid taller crowned, entoconid and hypoconid taller crowned, and larger hypoconulid shelf.
Eucyon davisi differs from Canis ferox and C. lepophagus in its smaller size and less robust skull and jaws; frontal sinus ends well before frontoparietal suture; jugal shallower relative to length of skull; width of skull across cheek teeth greater relative to length of skull; sagittal crest weaker; inion wider (never narrows to a point); premolars less robust; p4 anterolabial border generally less rounded; M1 paracone and metacone lower crowned and nearly subequal in size with stronger labial cingulum and stronger parastyle; m1 talonid without transverse crest between entoconid and hypoconid and hypoconulid shelf relatively smaller; angular process of mandible less expanded with smaller fossae for pterygoid muscle; and radius/tibia ratio less than 80%.
