Enhydrocyon
Enhydrocyon is an extinct genus of bone crushing dog which inhabited North America exclusively during the Oligocene living from around 28.7—22.0 Ma ( AEO) and existed for approximately .
Enhydrocyon dentition suggests this animal was a hypercarnivore or mesocarnivore. Species of Enhydrocyon were large, powerfully built carnivores with a short snout and deep jaws reminiscent of a jaguar. David Macdonald describes Enhydrocyon as a Canid-equivalent of a big cat-like carnivore.
