Diagnosis

|---|---|---|
| R. H. Tedford et al. 2009 | Canis tho ̈oides differs from C. lepophagus and resembles more derived species of Canis in its wide premolars, especially p4 with its posterolingual cingular shelf; like C. aureus, it differs from C. ferox in possessing primitive states of derived features of that and other crown group species. The P4 protocone extends anterior to the para- cone; I3 not markedly enlarged, with weak median cingulum; p4 principal cusp exceeds m1 paraconid in height; m1 anterior face of paraconid vertical or nearly so; m3 bicuspid. The isolation of all premolars by diastemata seems an autapomorphy in C. tho ̈oides. |
