Stephen Wroe through the use of finite element analysis concludes that *Agriotherium africanum had the strongest bite of any known terrestrial animal. Arctotherium was also one of the biggest bears that ever lived. Everything considered, paleobiologists conclude that the giant short-faced bear ate only meat. The closest living relative would be the spectacled bear (Tremarctos ornatus). It could weigh up to 4500lbs and stand at 14 feet tall, absolutely dwarfing even arctodus simus.
