Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. E. Jasinski and S. C. Wallace 2015 | Member of Cynarctus based on having enlarged M2s with posterior (distal) expansions (Wang et al., 1999), in turn making it a member of the Borophaginae and the Canidae. Further diagnosed from other species of Cynarctus by the prominent degree of posterior expansion of the M2 concentrated with the posterior cingulum; reduction of the labial cingulum lateral to the metacone; lack of expansion labially and/or posteriorly in the metacone; enlarged metaconule; enlarged lingual cingulum and hypocone; less pronounced posterior expansion near the hypocone; less developed metastyle; relatively weak posterior cingulum; and slightly pronounced labial cingulum near the anterior of the tooth. |
