Did bears exist in prehistoric times?
The short-faced bear (Arctodus sp.) is an extinct bear genus that inhabited North America during the Pleistocene epoch from about 1.8 Mya until 11,000 years ago. It was the most common tremarctine bear in North America and many of its fossils have been found in the La Brea tar pits in southern California.
What was the biggest bear that ever lived?
The largest bear on record in modern times was a 2,200-pound (998-kilogram) polar bear shot in Alaska in the 19th century.
Is the short-faced bear still alive?
The short-faced bear became extinct about 11 000 years ago. The cause is perhaps partly the earlier extinction of some of the large herbivores that it may have preyed upon or scavenged, and partly increased competition with the smaller grizzly bear that entered North America from Eurasia.
Was the dire bear real?
The popular show ‘Game of Thrones’ brought the fictional ‘direwolf’ to the screen, depicting them as intimidating beasts. But humans living in ice age North America had to deal with the real thing. Dire wolves (Canis dirus) were a canine species that hunted the plains and forests.

What killed the cave bear?
Twenty thousand years later, cave bears vanished. Some researchers have proposed that climate change felled the bears. Ice sheets advanced and shrank during the Pleistocene Epoch, the period from 2.6 million to 11,700 years ago. Wear on the bears’ teeth suggests the animals mostly ate plants.
Who would win a bear or a gorilla?
A grizzly beats a silverback 10 times out of 10. The average silverback weighs around 350 pounds and stands at 5-and-a-half feet tall. Their long arms give them the reach advantage on a grizzly, but that’s about it.

It may have died out due to competition with a large Pleistocene subspecies of black bear (Ursus americanus amplidens) and due to brown/grizzly bears (Ursus arctos) invading from the west near the end of the Ice Age.
Did dire wolves exist?
Thanks to the hit television series Game of Thrones, the dire wolf has gained a near-mythical status. But it was a real animal that roamed the Americas for at least 250,000 years, until it became extinct towards the end of the last ice age around 13,000 years ago.
