Australohyaena antiqua (Forasiepi et al. 2014; Late Oligocene; UNPSJB PV 113; Fig. 1) was originally nested with Borhyaena, but here nests with a previously untested taxon, Oxyaena (Fig. 1). Australohyaena is larger and more robust, but the orbit is no larger. The horizontal bar jaw joint makes the jaw a simple hinge with not transverse action possible. The jaw joint falls below the tooth row. The frontals were originally considered nasals.
If you think
marsupial Australohyaena looks like a placental lion (genus: Panthera leo), I agree with you (Fig. 2).
