---|---|---|
P. E. Kondrashov and S. G. Lucas 2004 | Large arctocyonids that differ from Arctocyonides in having less bunodont lower molars with better devel- oped crests; differ from Anacodon in having large lower canines with well developed shearing surfaces and in the shape of the talonid basin of the lower molars, which is triangular, not rectangular. The genus Arctocyon differs from Colpoclaenus and Mentoclaenodon in lacking the crenulations of the enamel on the upper and lower molars. |
