Borhyaena is an extinct genus of South American metatherian, living between 17.5 and 15.5 million years ago in Patagonia, Argentina (Santa Cruz and Sarmiento Formations) and Chile (Río Frias Formation).[2]
Description
Borhyaena was a predator and had a large head and a long, powerful neck similar to living hyenas. Its legs were cursorial, albeit less specialized than those of wolves or the marsupial thylacine. The most complete specimen is estimated to have weighted 23 kilograms (51 lb) and stood 50 centimetres (1.6 ft) at the shoulders.[3]
