("crushing dog") is an extinct genus of the Phlaocyon and a Borophaginae terrestrial canine which inhabited most of North America during the Whitneyan stage of the Early Oligocene through Late Hemingfordian stage of the Early Miocene epoch 33.3—16.3 Mya existing for approximately . 17.3 million years [1 ]
Taxonomy [ edit ]
Phlaocyon was about 80 centimetres (31 in) in body length, and looked more like a cat or raccoon than a dog, but its skull anatomy shows it to be a primitive canine. Phlaocyon probably lived like a raccoon, often climbing trees. Its head was short, wide, and had forward-facing eyes. Unlike modern canines, Phlaocyon had no specialised teeth for slicing flesh. It is thought to have been an omnivore. [2 ]
