Extinct subtribe of carnivores
Borophagina is a subtribe of the Borophaginae , a group of extinct canids . They inhabited much of North America from the Early Miocene to the Zanclean stage of the Pliocene , 20.6—3.6 Mya , and existed for approximately 17 million years .[ 1]
Like some other borophagines, they were short-faced, heavy-jawed canids[ 2] [ 3] although the group included both omnivorous and hypercarnivorous species.[ 4]
