Could Gorgosaurus survive in North America today?; This scenario has no people, so there is ice age megafauna

So, how would a population of gorgosaurus survive in north america today? Discuss. ( In this scenario, there are no humans alive and diseases don't count)

Because gorgosaurus lived in the frigid north during the cretaceous, it'd have no problem surviving with it's feathered coat.

Assuming no humans, for some reason, and assuming it could handle the modern atmosphere and modern mammals provide the right mix of nutrients, than maybe.

It would end up being awfully dependent on bison and moose for food (or if current moose habitat is too cold, just bison).

I suspect that elk would probably a bit too quick and agile to catch regularly, especially in forests, and I doubt deer or pronghorns would be worth it.

Depending on breeding behavior, they'd probably suffer losses from wolves or coyotes to their nests if only one parent guarded the nest, but maybe not if both did.

In modern North America, with the habitat as it is? No way. Not enough food or space.

the scenario is this: no humans have ever evolved, and a population of gorgosaurus suddenly finds themselves in north america. Note that because there is no humans around, the land is much more wild. This might also mean that some ice age animals still survive.

Gorgosaurus would be a top predator, it would prey on even the large sabertoothed cats....

How many sabretoothed cats have you seen in modern north america?

OK. I thought apart from that no humans are there, the fauna is like it is today. If some ice age animals still exist, i think it´s also easier for gorgosaurus to survive, as it has much larger and more prey animals.

They'd probably do well. Gorgosaurus would likely prey on Bison and Moose and would likely dominante Wolves even in packs over kills. It would probably be on par with Smilodons though.

Predators don't prey on other predators. They see each other as competitors. Gorgosuarus would view Smilodons as that.

But it was far larger than smilodon. Don´t predators prey on smaller predators?

Well Lions live in Africa with Hyenas, and they're bigger. Yet they don't prey on them. They just compete.

I don't even like Gorgosaurus...but it's too large to even take wolves seriously...and it's vastly larger than Smilodon...and part of the scenario was to not take immune systems into account...

Prey can't always be herbivores, otherwise all predators would be apex predators, which is obviously not true...Orcas prey on sharks, crocodiles prey on lions and hyenas, and this is worth a read:

Predators do prey on other predators...
