Phlaocyon

Phlaocyon ("crushing dog") is an extinct genus of the Borophaginae and a 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.

Taxonomy
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.

Body mass
Two specimens were examined by Legendre and Roth for body mass.[3]
 * Specimen 1 was estimated to weigh 1.81 kg (4.0 lb).
 * Specimen 2 was estimated to weigh 1.87 kg (4.1 lb).
