Range of Enhydrocyon fossil evidence

Enhydrocyon is an extinct genus of bone crushing canid which inhabited North America during the Oligocene and Early Miocene, 30.8—20.4 Ma, existing for approximately 11 million years. [1]

Enhydrocyon's dentition suggests this animal was a hypercarnivore or mesocarnivore.[2] Species of Enhydrocyon were relatively large, powerfully built carnivores with a short snout and deep jaws reminiscent of a jaguar.[3] These features give the skull a shape resembling that of the extant sea otter (Enhydra), prompting the scientific name.[4] With an estimated weight of about 10 kilograms (22 lb), this was the earliest genus of canid adapted to be specialized predators.[4]
