Temporal range: Late Eocene–Middle Miocene
|Skull of Mesocyon coryphaeus|
Hesperocyoninae is a subfamily of extinct canids.
This disused subfamily was endemic to North America, living from the Duchesnean stage of the Late Eocene through to the early Barstovian stage of the Miocene, lasting around 20 million years. It comprises ten recognized genera and twenty six recognized species; among these, four genera and species are new. Four major lineages can be defined based on shared characteristics:
The genus Caedocyon probably forms a distinct clade of its own.
Hesperocyon, which lacks the shared derived characters that would include it within any of the aforementioned clades, is possibly ancestral to many of the lineages. There is evidence that the Paraenhydrocyon clade may be directly descended from Hesperocyon gregarius. According to Xiaoming Wang, Hesperocyon coloradensis provides an important link between H. gregarius and the Mesocyon-Enhydrocyon clade.
