Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. H. Tedford et al. 2009 | Chrysocyon shares a number of synapomorphies (Tedford et al., 1995) with all other Cerdocyonina, including zygomatic arch with wide masseter muscle scar and corresponding enlarged insertion for medial masseter ventral to masseteric fossa of ascending ramus, and coronoid process with long base relative to height. It shares with more derived members of South American clade blunt angular process, fossa for inferior ramus of median pterygoid expanded, and M1–M2 more quadrate in occlusal outline so they appear transversely narrow for their length. A number of autapomorphies distin- guish Chrysocyon from other South Ameri- can canines: it primitively retains palate shorter than toothrow; like Canis, its fore- limb is long relative to hindlimb (the radius/ tibia ratio is greater than 90%), although it shows great limb elongation (humerus + radius more than 50% of head-body length). |
