==Taxonomy== thumb|left|H. gregarius Hesperocyon was assigned to Borophagini by Wang et al. in 1999 and was the earliest of the canids to evolve after the Caniformia-Feliformia split some 42 million years ago. Fossil evidence dates Hesperocyon gregarius to at least 37 mya, but the oldest Hesperocyon has been dated at 39.74 mya from the Duchesnean North American land mammal age.
