Arctodus
Bears have roamed the world for millions of years. The North American short-faced bear, or, Arctodus, is one of the most terrifying extinct animals we wouldn’t want to accidentally stumble upon in our backyard. There are two species, the Arctodus pristinus, the lesser short-faced bear, or the Arctodus simus, the giant short-faced bear, which is the largest terrestrial mammalian carnivores that have ever roamed the planet. They inhabited North American soil from the latest Pilocene to the Holocene epoch, up until roughly 10,000 years ago. Considering some of these extinct animals died off millions of years ago, 10,000 years seems pretty recent (Wikipedia).
