Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. H. Tedford et al. 2009 | Canis edwardii is dis- tinguished from C. ferox by a suite of synapomorphies the former shares with C. latrans and the wolves: tip of p3 principal cusp lies below those of adjacent premolars and its cingulum lies entirely below that of p4; principal cusp of p4 lies below paraconid of m1, anterior face of m1 slants posteriorly; paracone of M1 is larger than metacone; maxillary-jugal suture is acute; m3 is single- cusped; and incisive foramen may extend posterior to canine alveolus.
Canis edwardii is larger than C. latrans and differs in skull and some tooth proportions as well as lacking two synapomorphies that group C. latrans with the wolves: elongation of distal part of forelimb (radius/tibia ratio ,90%), and sagittal crest extends onto frontal bone. |
