If Certosaurus were alive in North America today?

So I was just wondering, but let's just say if Ceratosaurus were alive today in North America. How well do you see Ceratosaurus being able to survive.

In my opinion it would survive. It be the top predator in North America. It would probably dominate Wolf Packs and Bears over kills. It would also prey on Deer and other herbivores. That's how I see it happening. Then again maybe Ceratosaurus would only survive in the southern United States and Mexico, where there's no snow in the Winter, but would still be enough animals for it to prey on.

What about you guys? What do yout hink. Would it survive or not and if so or not. How would it or why wouldn't it.

It would easily dominate the warmer areas

I agree with that. The only parts of North America I think it would live in is the southern United States and Mexico just like i said in the first post of this topic.

They wouldn't be able to find food and go extinct very quickly.

There's lot of food that Ceratosaurus could prey on. It could mainly prey on Deer, Elk, and other herbivores. I think that would be enough for it to survive.

lol, they could prey on the local wildlife

How will it catch them?

What makes it so much better than all the modern predators that went extinct in North America?

EDIT:
Certaosaurus is quite outgunned in the evolutionary arm's race by today's standards.

Ceratosaurus for all we know could of used ambush or even worked in pairs. That's how. Plus I wouldn't say it is outgunned in evolutionary arm's race by today's standards. It has size to help it, which would allow it to dominate other predators such as Wolf Packs and Bears.

How is Ceratosaurus "outgunned" by today's standards? Sure it may be less intelligent than wolves/bears, but so are alligators. Ceratosaurus is also quite fast and agile too.

Ceraosaurus for all we know could of used ambush or even worked in pairs. That's how.
Ambush?

Jump to 3:00.
See how a slow moving animal (fast relative to size or not, Ceratosaurus is far larger than the bear, and also needs far more calories to grow and survive), despite launching an ambush from ridiculously close range, still fails to catch an example of today's highly specialised adult cursor?
Do you think Ceratosaurus would do a better job of ambushing than the bear-with its towering bipedal height? I'm not aware of research regarding their crouching ability, but being able to actually accelerate quickly from a crouched position could be another big problem.

Working in pairs?
All research on modern social carnivores (wolves, AWDs, lions) I'm aware of finds that if finding food were their only concern they'd be better off alone. It is extremely unlikely that Ceratosaurus would show more sophisticated behaviour patterns.

Not out-gunned?
Alligators fill an entirely different niche where low metabolism is extremely beneficial, and are very well adapted for it.
Compared to all recently extinct placental carnivores Ceratosaurus is very poorly adapted to the niche of active predator.
Even the basics like binocular vision!
Critically, among modern bird, mammal, reptile, and amphibian species the relative size of the brain is consistently linked to success and failure of becoming an invasive species.

Consider the Great American Interchange where the smaller brained South American wildlife was mostly wiped out by the bigger brained North America.
Or the prevalence of invasive species by region; small brained Australian fauna need human intervention to survive the introduction of larger brained placental mammals.



Consider the red queen hypothesis but related to evolutionary arms races between predators and prey, rather than host and parasite.


I need some substantially stronger evidence than wishful thinking that Ceratosaurus was so cool and badass to fly in the face of all the modern patterns and trends that predict it to be an abysmal failure!

Well T-Rex likely hunted in ambush and it's really big, so I think Ceratosaurus would too. I also got the working in pairs from Jurassic Fight Club from an episode, which featured two Ceratosaurus fighting an Allosaurus.

My points were "it wouldn't do nearly enough to help" and "it wouldn't help at all", not that they didn't do it.

Well in my opinion I still think Ceratosaurus would surive today, but that is just me.

Yes, just you and every other poster who voted.
Me and all the scientific research regarding success and failure of species are alone together.

Well I accept your opinion anyway. :)
