Range of Borophagini based on fossil distribution

Borophagini is aclade or tribe of thesubfamilyBorophaginae. This is anextinct group ofterrestrialcanids that were endemic and widespread throughoutNorth America andCentral America which lived during theGeringian stage of theOligocene epoch to theZanclean age of theEarly Pliocene living 30.8—3.6Mya existing approximately27.2 million years.^[1]

Borophagini were short-faced, heavy-jawed canids, usually massive in size. They were primarilycarnivores butdentition demonstratesomnivore traits.^[2][3]

Borophagini was named by Simpson (1945)^[4] [credited to Simpson because he named Borophaginae]. It was assigned to Borophaginae by Wang et al. (1999)^[5] and Wang et al. (2004).^[6]

The subtaxa or subtribes are:Aelurodontina,Borophagina, andCynarctina.Phlaocyonini is a sister taxon.
