Diagnosis
ReferenceDiagnosis
R. H. Tedford et al. 2009Canis 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.
