  Quotations
  Except in Borophagus and late Hemphillian Osteoborus, there is an entepicondylar foramen in borophagines, found in no living canid or hyaenid, but characteristic of felid humeri. In C. lupus and borophagines the lateral epicondyle bears two or more facets for the origin of the carpal and digital extensors and the supinator muscle.

  The arctoids and early borophagine canids are the hallmark of the North American Mid-Miocene epoch.

  The history of the borophagines also begins with a small fox-like form, Archaeocyon, in the late Oligocene.
