Bears of the Pleistocene

[GrizzlyClaws]

I do believe that upon the arrival of the Grizzlies, they had witnessed the downfall of the megafaunas like the SF bears and American lions.

The Grizzlies would likely avoid the direct confrontation with the larger SF bears, but the Grizzlies managed to outcompete the SF bears with its versatility in term of food acquisition. The Grizzlies can rely on a larger amount of vegetable diet, whilst the SF bears had to depend on larger quantity of meat.

In comparison, to tackle against the smaller American lions, I think the Grizzlies would frequently try to steal their carcasses. For its sake of survival, a weakened American lion would have no choice but to defend relentless against the food robber. A wounded Grizzly had higher chance to survive than a wounded lion, because the lion would be crippled and unable to hunt anymore, while the bear can rely on other food sources.

That's why the Grizzlies can manage to extrude these two megafaunas permanently out of the food chain in the North America. Reply
