Won’t it starve in a month?
Good question. Many modern day reptiles can go a long time without food. But a t rex is many orders of magnitude bigger than anything we have now. I did do a zoology major at uni, but my physiology knowledge sucks (unsurprising given I barely passed it).
Theropods were warm blooded, like birds. They would not be able to endure without eating for weeks and months at a time like modern cold blooded reptiles.
You’re conflating how warm bloodedness works in mammals with how it would work in theropods. They were warm blooded because they could not shed heat from metabolic processes due to their volume to surface area ratio, not because their bodies needed it. We still do not understand how it actually worked. This is evidenced by us still not knowing the reason why stegosaurus had plates, Spinosaurus had their sail etc.
Also, some birds can go weeks without food during migration or injury. Further to this, theropods are many magnitudes of size larger than birds. They would have far greater fat stores than modern birds.
Disclaimer, this is based on my 16yr old zoology major, and we are in a dinosaur discovery golden age so something may have changed.
I think the interesting question is, how the the lower oxygen concentration on the atmosphere will affect the T-Rex. Is it low enough to kill it? Will it just weaken it enough that the heat produced will do some damage? I have no idea.
I would wait for it to fall asleep and then make a big anti T-rex circle around it so it cant escape.
That’s smart
I don’t think he would last long with our current oxygen levels, there is a reason why such giant creatures don’t exist anymore.
On top of that like comments said if we just waited out he would starve to dead, even if we were not provided food.
*Edit
Well looks like I was wrong, thx for clarifying that out.
Really though the reason for big animals not being as prevelant anymore was really the oxygen levels Idk where I got that from.
But then it is really weird how the evolution meta didn’t evolve back to the huge beasts we see on books, someone said in the comments that it was due to the mammals success, if so it puts things really into perspective.
The largest animal we have known to ever live is alive right now, the blue whale.
The ocean doesn’t count
In this particular case, it does. Whales are air breathing mammals.
Yes, but they spend most of their lives under water, only coming up briefly to breathe. Being under several atmospheres of pressure changes your air requirements.
Whether those requirements go up or down, I’m not sure.
I know it’s green text but come on. Even T-Rex sleep. Wait for that, poke its eyes out, cut its tendons and then just go death by a thousand cuts on that big lizard.
Also, most apex predators are heavy sleepers because they have absolutely nothing to be scared of when they’re asleep. As an example, male lions sleep for 18-20 hours a day.
Well, it sure as fuck will wake up if you stab its eye out. If I had to bet I still would pick the one-eyed angry T-Rex.
We don’t know if they ever slept. We don’t even know if they had fur or not.
I just had to stop me from going down a whole rabbit hole about sleeping sharks. So I’m just going to make this point:
Chickens and crocodiles sleep, and they are basically dinosaurs so: Checkmate.
Seriously though, sharks are pretty interesting creatures! https://animalhype.com/fish/do-sharks-sleep/
