Borhyaena is an extinct genus of South American metatherian within borhyaenaid, a family of mammalian predators that was part of the now extinct order Sparassodonta. The genus lived from 21 to 15.5 million years ago from the Early to Middle Miocene. The genus contains two species, B. macrodonta and B. tuberata. Compared to other sparassodonts, Borhyaena was found to have more adaptations towards cursoriality, however it still likely wasn’t a specialized cursorial predator as seen with wolves. It is believed that, like striped hyenas, Borhyaena searched and hunted for smaller prey without cooperation from other individuals, and other experts believed it was capable of hunting prey larger than itself.

Its legs were adapted to cursoriality, albeit less specialized than those of wolves or the thylacine. The most complete specimen is estimated to have weighted and stood at the shoulders. One study suggested that Borhyaena may have been even larger, weighing . The footplate of the stapes of Borhyaena tuberata has a rounded morphology, and the stapedial ratio of the species, defined as the maximum length of the stapedial footplate divided by the maximal width of the footplate, was approximately 1.6. ==References== ==External links==
