Ectopocynus
Ectopocynus ("strange dog") is an extinct genus of bone crushing canid which inhabited North America from the Oligocene to the Early Miocene. It lived from 33.3 to 16.0 Ma and existed for approximately . Remains of "Ectopocynus" are limited to mandibles and teeth only. These reveal that the animal had simple, robust, and blunt yet massive premolars and reduced or lost cusps on the lower molars. In this respect, "Ectopocynus" had many of the characteristics of "Enhydrocyon". This dentition suggests this animal was a hypercarnivore or mesocarnivore.
