Phlaocyon
''Phlaocyon'' (from Greek ''phlao'', "eat greedily" and ''cyon'', "dog") is an extinct genus of the Borophaginae and a terrestrial canid 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 . It is closely related to ''Cynarctoides''. ==Phylogeny== When discovered in the 19th century and during the following decades, ''Phlaocyon'' was thought to be ancestral to raccoons because of shared convergent adaptations toward hypocarnivorous dentitions, but was the first to discover the canid nature of the middle ear region in ''P. leucosteus'' and ''Phlaocyon'' in now believed to be part of very diverse clade of hypocarnivorous canids, the Phlaocyonini, and only distantly related to raccoons. ''P. mariae'' and ''P. yatkolai'', both known from isolated teeth and fragmentary material, are the largest and most derived species, and both display a tendency away from the hypocarnivorous dentition of the genus and towards a more hypercarnivorous dentition.
