If Dinosaurs were living today? ?

Question

Lets say we bring back a dinosaur today. I am sure it wouldn't last very long alive, what would be the main factors of its death?(oxygen, diet, etc.) Would the size of the dinosaur matter? Even with ocean dwelling dinosaurs/fish/reptiles, would it matter? And finally, which do you think would last longer? a dinosaur from the Cretaceous, Jurassic, or Triassic?

Answer 1

If dinosaurs were subjected to the same condition, there is no guarantee they will survive in a new environment, this includes all the factors such as pollution, carbon/oxygen level, temperature, etc.

And besides, we can probably manage them.  We have the brains. lol.

I would say Cretaceous.  I don't know much about era of dinosaur but if cretaceous is the closest to our era, then that perhaps would last longer.

Size don't matter.  We have elephants and whatever animal which are bigger than us.  I think it's more on the number and their survival rate.

Answer 2

wed be ants

Answer 3

> would be the main factors of its death?

Disease.  The dinosaur would have no immunity against the bacteria of today, and even something like salmonellosis or E. coli could kill the poor thing.

You'd have trouble finding the right kind of food for a herbivore dinosaur from the Triassic or Jurassic.

Size wouldn't matter.  Bacterial disease will kill 'em any size.  But if you had a smaller dinosaur, you could keep it alive longer in isolation and with antibiotic treatments.

If you're looking for which period, like I mentioned, you'd have trouble getting food for a Triassic or Jurassic herbivore;  their food plants are extinct.  Carnivores wouldn't matter -- you'd feed them chicken meat, LOL.

About the oxygen level -- we don't know what the oxygen level was during the Mesozoic.  The subject is speculative, and I've seen people defending both "higher than today" and "lower than today."

Answer 4

It will be very difficult for it to adapt to today's environments! A dinosaur from the Cretaceous would adapt quickest!

Answer 5

Well... after a little sniffling around, I find that dinosaurs apparently experienced oxygen percentages between 25 and 35%, both of which are significantly higher than what we have today. So it would probably be a factor - would be like being high in the mountains.

It's also a lot colder than it was back then...

Diet might be a factor, I am not certain...

Huhh. Jurassic Park becomes that much more ridiculous. That T.Rex should have keeled over, panting and wheezing, after two or three steps.

Answer 6

They will not survive for long.

The oxygen consumption is too high.

The herbivores will consume too much plant material which will further reduce our oxygen supply.

Their influence on current food chains and webs will cause mass extinction of many species.

Because of their body size they will struggle to maintain body temperature with our current global warming.

Their influence on man made structures will make them unwanted.
