Borophagus diversidens
''Borophagus diversidens'' ("devouring glutton") is an extinct species of the genus ''Borophagus'' of the subfamily Borophaginae, a group of canids endemic to North America from the early Miocene epoch through the Pliocene epoch 4.9—1.8 Ma. ''Borophagus dudleyi'' existed for approximately .〔(PaleoBiology Database: ''Borophagus diversidens'', basic info )〕
==Overview==
''Borophagus diversidens'' was named by Cope in 1892. Members of its subfamily, Borophaginae, are loosely known as "bone-crushing" or "hyena-like" dogs. Though not the most massive borophagine by size or weight, it had a more highly evolved capacity to crunch bone than earlier, larger genera such as ''Epicyon'', which seems to be an evolutionary trend of the group (Turner, 2004). During the Pliocene epoch, ''Borophagus'' began being displaced by ''Canis'' genera such as ''Canis edwardii'' and later by ''Canis dirus''. Early species of ''Borophagus'' were placed in the genus ''Osteoborus'' until recently, but the genera are now considered synonyms.〔 ''B. diversidens'' possibly led a hyena-like lifestyle scavenging carcasses of recently dead animals.
