Tedford et al. 2009Leptocyon vulpinus differs from L. douglassi and Leptocyon gregorii in its larger size, stronger and more distinct parastyle on M1, m1 with trigonid and talonid wider relative to length, andproportionally larger m2 with larger and more distinct paraconid. L. vulpinus differs from L. mollis in its larger size, as well as larger and taller crowned premolars.
