Patriofelis ulta
Patriofelis ultaPatriofelis ulta was a robust oxyaenid predator that stalked the subtropical river systems and dense woodlands of middle Eocene North America. Resembling a heavy, short-limbed felid or wolverine, it possessed crushing premolars and powerful jaw musculature suited for cracking bones and tough hides. Its broad, flexible feet and sturdy skeleton suggest an ambush hunter adapted to grappling heavy prey in close quarters rather than chasing it down over open ground.
