Borhyaena was a Sparassodont that live in Patagonia during the early Miocene.

I couldn't find many references for this, and I'm not too exactly too sure how to accurately reconstruct something from just its bones, so I had to use my imagination a bit.

Something went wrong with the top one's face. It's been very hot and dry where I live, so perhaps the water evaporated to quickly. I'm not sure.
